GridView

in namespace DotVVM.BusinessPack.Controls

A multi-purpose grid control with advanced binding and templating options and sorting support.

Usage & Scenarios

This control is different from the built-in GridView and is not derived from it.

The Business Pack GridView control is a advanced grid control with many features.

The version 3.0 supports the following features (except of the features supported in the built-in GridView):

Inline Insert row
Column Hiding
Column Reordering
Column Resizing
Row Reordering
Customizable Filters
Row Detail

The following features are planned to be added in the following releases:

Grouping

Sample 1: Basic Usage

The DataSource property expects BusinessPackDataSet<T> object which contains all necessary information about the data presented by the control.

The Columns collection specifies all columns in the control.

The HeaderText property of the column defines the text displayed in the column header.

Column Types

The <bp:GridViewTextColumn> renders a text, numeric or date values in the cell. The Value expression specifies the property to be rendered. The FormatString property specifies the format of the value (for numeric and date columns).

The <bp:GridViewTemplateColumn> renders a specified template in the grid cell.

<bp:GridView DataSource="{value: Customers}">
    <Columns>
        <bp:GridViewTextColumn Value="{value: Id}" HeaderText="ID" />
        <bp:GridViewTextColumn Value="{value: Name}" HeaderText="Name" />
        <bp:GridViewTextColumn Value="{value: BirthDate}" HeaderText="Birth Date"
                               FormatString="dd.MM.yyyy" />
        <bp:GridViewTemplateColumn>
            <ContentTemplate>
                <b>{{value: Orders}}</b>
            </ContentTemplate>
        </bp:GridViewTemplateColumn>
    </Columns>
</bp:GridView>

using DotVVM.BusinessPack.Controls;
using DotVVM.Framework.Controls;
using DotVVM.Framework.ViewModel;


namespace DotvvmWeb.Views.Docs.Controls.businesspack.GridView.sample1
{
    public class ViewModel : DotvvmViewModelBase
    {
        public BusinessPackDataSet<Customer> Customers { get; set; } = new BusinessPackDataSet<Customer>()
        {
            SortingOptions = { SortExpression = nameof(Customer.Id) }
        };

        public override Task PreRender()
        {
            if(Customers.IsRefreshRequired)
            {
                Customers.LoadFromQueryable(GetQueryable(15));
            }

            return base.PreRender();
        }

        private IQueryable<Customer> GetQueryable(int size)
        {
            var customers = new List<Customer>();
            for (var i = 0; i < size; i++)
            {
                customers.Add(new Customer { Id = i + 1, Name = $"Customer {i + 1}", BirthDate = DateTime.Now.AddYears(-i), Orders = i });
            }
            return customers.AsQueryable();
        }
    }
}

        public DateTime BirthDate { get; set; }
        public int Orders { get; set; }
    }
}

Sample 2: Grid Headers

When the DataSource is empty, the grid will not appear at all by default. The ShowTableWhenNoData property can be used to make the grid header visible even if there are no data.

The HeaderCssClass property of the column sets the CSS class to the column header cell.

To place custom content in the header cell, you can use the HeaderTemplate property.

<bp:GridView DataSource="{value: Customers}"
             ShowTableWhenNoData="true">
    <Columns>
        <bp:GridViewTextColumn Value="{value: Id}"
                               HeaderText="Customer ID" />
        <bp:GridViewTextColumn Value="{value: Name}"
                               HeaderCssClass="gridview-header-highlight">
            <HeaderTemplate>
                <i>Name</i>
            </HeaderTemplate>
        </bp:GridViewTextColumn>
    </Columns>
</bp:GridView>

using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using DotVVM.BusinessPack.Controls;
using DotVVM.Framework.Controls;
using DotVVM.Framework.ViewModel;


namespace DotvvmWeb.Views.Docs.Controls.businesspack.GridView.sample2
{
    public class ViewModel : DotvvmViewModelBase
    {
        public bool ShowHeaderWhenNoData { get; set; } 
        public BusinessPackDataSet<Customer> Customers { get; set; } = new BusinessPackDataSet<Customer>()
        {
            SortingOptions = { SortExpression = nameof(Customer.Id) }
        };

        public override Task PreRender()
        {
            if(Customers.IsRefreshRequired)
            {
                Customers.LoadFromQueryable(GetQueryable(15));
            }

            return base.PreRender();
        }

        private IQueryable<Customer> GetQueryable(int size)
        {
            var customers = new List<Customer>();
            for (var i = 0; i < size; i++)
            {
                customers.Add(new Customer { Id = i + 1, Name = $"Customer {i + 1}" });
            }
            return customers.AsQueryable();
        }
    }
}

using System;
using System.Linq;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.GridView.sample2
{
    public class Customer
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string LastName => !string.IsNullOrWhiteSpace(Name) ? Name.Split(' ').LastOrDefault() : "";
        public DateTime BirthDate { get; set; }
        public int Orders { get; set; }
    }
}

Sample 3: Grid Footer

By default, the grid doesn't render any footer.

If any of the columns specifies its FooterTemplate property, the footer row will appear.

The FooterTemplate property of the control can be used to render an additional footer row for the entire table.

<bp:GridView DataSource="{value: Customers}">
    <Columns>
        <bp:GridViewTextColumn Value="{value: Id}" HeaderText="ID" />
        <bp:GridViewTextColumn Value="{value: Name}" HeaderText="Name" />
        <bp:GridViewTextColumn Value="{value: Orders}" HeaderText="Orders" 
                               FooterCssClass="gridview-footer">
            <FooterTemplate>
                <p>Total orders: {{value: TotalOrders}}</p>
            </FooterTemplate>
        </bp:GridViewTextColumn>
    </Columns>
</bp:GridView>

using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using DotVVM.BusinessPack.Controls;
using DotVVM.Framework.Controls;
using DotVVM.Framework.ViewModel;


namespace DotvvmWeb.Views.Docs.Controls.businesspack.GridView.sample3
{
    public class ViewModel : DotvvmViewModelBase
    {
        public int TotalOrders => Customers.Items.Sum(c => c.Orders);

        public BusinessPackDataSet<Customer> Customers { get; set; } = new BusinessPackDataSet<Customer>()
        {
            SortingOptions = { SortExpression = nameof(Customer.Id) }
        };
        
        public override Task PreRender()
        {
            if(Customers.IsRefreshRequired)
            {
                Customers.LoadFromQueryable(GetQueryable(15));
            }

            return base.PreRender();
        }

        private IQueryable<Customer> GetQueryable(int size)
        {
            var customers = new List<Customer>();
            for (var i = 0; i < size; i++)
            {
                customers.Add(new Customer { Id = i + 1, Name = $"Customer {i + 1}", Orders = i });
            }
            return customers.AsQueryable();
        }
    }
}

using System;
using System.Linq;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.GridView.sample3
{
    public class Customer
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string LastName => !string.IsNullOrWhiteSpace(Name) ? Name.Split(' ').LastOrDefault() : "";
        public DateTime BirthDate { get; set; }
        public int Orders { get; set; }
    }
}

Sample 4: Sorting

By default, the sorting is not enabled on any column. You can use the AllowSorting property to enable it.

The columns which have the Value, will sort using the specified expression by default. If the column doesn't have this property (e. g. GridViewTemplateColumn), or if you need to use another property to define the order of the rows, you can use the SortExpression property. This property takes precedence over the Value.

To customize the icons for sorting, you can use the SortAscendingHeaderCssClass and SortDescendingHeaderCssClass properties which specify the CSS class to be added to the header of the column which is used for the searching.

You can also set these properties on the GridView control instead of declaring them for each column separately, using GridViewColumn.SortAscendingHeaderCssClass="value".

<bp:GridView DataSource="{value: Customers}">
    <Columns>
        <bp:GridViewTextColumn Value="{value: Id}"
                               HeaderText="Id"
                               AllowSorting="true"
                               SortAscendingHeaderCssClass="sort-asc-custom"
                               SortDescendingHeaderCssClass="sort-desc-custom" />
        <bp:GridViewTextColumn Value="{value: Name}"
                               HeaderText="Name"
                               AllowSorting="true"
                               SortExpression="LastName" />
        <bp:GridViewTextColumn Value="{value: Orders}"
                               HeaderText="Orders"
                               AllowSorting="true" />
    </Columns>
</bp:GridView>

using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using DotVVM.BusinessPack.Controls;
using DotVVM.Framework.Controls;
using DotVVM.Framework.ViewModel;


namespace DotvvmWeb.Views.Docs.Controls.businesspack.GridView.sample4
{
    public class ViewModel : DotvvmViewModelBase
    {
        public BusinessPackDataSet<Customer> Customers { get; set; } = new BusinessPackDataSet<Customer>()
        {
            SortingOptions = { SortExpression = nameof(Customer.Id) }
        };

        public override Task PreRender()
        {
            if(Customers.IsRefreshRequired)
            {
                Customers.LoadFromQueryable(GetQueryable(15));
            }

            return base.PreRender();
        }

        private IQueryable<Customer> GetQueryable(int size)
        {
            var customers = new List<Customer>();
            for (var i = 0; i < size; i++)
            {
                customers.Add(new Customer { Id = i + 1, Name = $"Customer {i + 1}", Orders = i });
            }
            return customers.AsQueryable();
        }
    }
}

using System;
using System.Linq;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.GridView.sample4
{
    public class Customer
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string LastName => !string.IsNullOrWhiteSpace(Name) ? Name.Split(' ').LastOrDefault() : "";
        public DateTime BirthDate { get; set; }
        public int Orders { get; set; }
    }
}

Sample 5: Paging

The paging relies on the DataPager control and the use of the BusinessPackDataSet<T> object.

<bp:GridView DataSource="{value: Customers}">
    <Columns>
        <bp:GridViewTextColumn Value="{value: Id}" HeaderText="ID" />
        <bp:GridViewTextColumn Value="{value: Name}" HeaderText="Name" />
        <bp:GridViewTextColumn Value="{value: BirthDate}" HeaderText="Birth Date" 
                               FormatString="dd.MM.yyyy" />
        <bp:GridViewTextColumn Value="{value: Orders}" HeaderText="Orders" />
    </Columns>
</bp:GridView>

<bp:DataPager DataSet="{value: Customers}" />

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using DotVVM.BusinessPack.Controls;
using DotVVM.Framework.Controls;
using DotVVM.Framework.ViewModel;


namespace DotvvmWeb.Views.Docs.Controls.businesspack.GridView.sample5
{
    public class ViewModel : DotvvmViewModelBase
    {
        private const int defaultPageSize = 5;

        public BusinessPackDataSet<Customer> Customers { get; set; } = new BusinessPackDataSet<Customer>()
        {
            PagingOptions = { PageSize = defaultPageSize },
            SortingOptions =  {SortExpression = nameof(Customer.Id) }
        };

        public override Task PreRender()
        {
            if(Customers.IsRefreshRequired)
            {
                Customers.LoadFromQueryable(GetQueryable(15));
            }
            return base.PreRender();
        }

        private IQueryable<Customer> GetQueryable(int size)
        {
            var customers = new List<Customer>();
            for (var i = 0; i < size; i++)
            {
                customers.Add(new Customer { Id = i + 1, Name = $"Customer {i + 1}", BirthDate = DateTime.Now.AddYears(-i), Orders = i });
            }
            return customers.AsQueryable();
        }
    }
}

using System;
using System.Linq;

namespace DotvvmWeb.Views.Docs.Controls.businesspack.GridView.sample5
{
    public class Customer
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string LastName => !string.IsNullOrWhiteSpace(Name) ? Name.Split(' ').LastOrDefault() : "";
        public DateTime BirthDate { get; set; }
        public int Orders { get; set; }
    }
}

Sample 6: Inline Editing

Enum InlineEditMode specifies whether the user will be able to edit rows directly in the grid. To enable editing set the value to SingleRow.

Every column has the AllowEditing property which specifies whether the particular column can be edited or not.

The columns also have the EditTemplate property which can be used to define a custom edit template for the cell.

The object that is currently being edited, is found by the Customers.RowEditOptions.EditRowId property which contains its primary key. The name of the property that is the primary key is set in Customers.RowEditOptions.PrimaryKeyPropertyName.

<bp:GridView DataSource="{value: Customers}"
             InlineEditMode="SingleRow">
    <Columns>
        <bp:GridViewTextColumn Value="{value: Id}"
                               HeaderText="ID"
                               AllowEditing="false" />
        <bp:GridViewTextColumn Value="{value: Name}"
                               HeaderText="Name" />
        <bp:GridViewTemplateColumn HeaderText="Birthdate">
            <ContentTemplate>
                <dot:Literal Text="{value: BirthDate}"
                             FormatString="dd.MM.yyyy" />
            </ContentTemplate>
            <EditTemplate>
                <bp:DateTimePicker SelectedDateTime="{value: BirthDate}"
                                   FormatString="dd.MM.yyyy"
                                   Mode="Date" />
            </EditTemplate>
        </bp:GridViewTemplateColumn>
        <bp:GridViewTextColumn HeaderText="Orders" Value="{value: Orders}" />
        <bp:GridViewTemplateColumn>
            <ContentTemplate>
                <dot:Button Text="Edit" Click="{command: _parent.EditCustomer(_this)}"/>
            </ContentTemplate>
            <EditTemplate>
                <dot:Button Text="Save" Click="{command: _parent.UpdateCustomer(_this)}"/>
                <dot:Button Text="Cancel" Click="{command: _parent.CancelEditCustomer()}"/>
            </EditTemplate>
        </bp:GridViewTemplateColumn>
    </Columns>

        public DateTime BirthDate { get; set; }
        public int Orders { get; set; }
    }
}

Sample 7: Inline Inserting

The InlineInsertMode property can be used to enable the inline insert feature on the grid. This feature adds an additional editable row to the table that can be used to add new items.

The InlineInsertRowPlacement property specifies whether the row is placed on the Top or the Bottom of the table.

In the column, you can then specify the InsertTemplate to provide a custom template for a cell in the insert row.

If you need to combine the inline insert with inline edit, you can provide both templates, or set only the EditTemplate. If the InsertTemplate is not set, the EditTemplate will be used.

<bp:GridView DataSource="{value: Customers}"
             AllowInlineInsert="true"
             InsertRowPlacement="Bottom">
    <Columns>
        <bp:GridViewTextColumn Value="{value: Id}"
                               HeaderText="ID"
                               AllowEditing="false" />

        <bp:GridViewTextColumn Value="{value: Name}"
                               HeaderText="Name" />

        <bp:GridViewDateTimeColumn Value="{value: BirthDate}"
                                   HeaderText="Birthdate"
                                   FormatString="dd.MM.yyyy"/>

        <bp:GridViewTemplateColumn HeaderText="Orders">
            <ContentTemplate>
                <dot:Literal Text="{value: Orders}" />
            </ContentTemplate>
        </bp:GridViewTemplateColumn>

    </Columns>
</bp:GridView>

<br />
<bp:Button Text="Add row"
           Click="{command: InsertNewCustomer()}"

Sample 8: Advanced Column Types

There are several columns which use various Business Pack controls in the insert and edit mode:

the GridViewComboBoxColumn renders a ComboBox control.
The GridViewCheckBoxColumn renders a CheckBox control.

The properties of the column have the same names and meaning like the properties of the control inside the cell.

<bp:GridView DataSource="{value: Orders}"
             InlineEditing="true">
    <Columns>
        <bp:GridViewTextColumn Value="{value: Id}"
                               HeaderText="Order ID" />

        <bp:GridViewComboBoxColumn Value="{value: DeliveryType}"
                                   DataSource="{value: DeliveryTypes}"
                                   HeaderText="Delivery type" />

        <bp:GridViewTemplateColumn HeaderText="Date">
            <ContentTemplate>
                <dot:Literal Text="{value: CreatedDate}"
                             FormatString="dd.MM.yyyy hh:mm" />
            </ContentTemplate>
            <EditTemplate>
                <bp:DateTimePicker SelectedDateTime="{value: CreatedDate}"
                                   FormatString="dd.MM.yyyy hh:mm"
                                   Mode="DateTime" />
            </EditTemplate>
        </bp:GridViewTemplateColumn>

        <bp:GridViewTemplateColumn>
            <ContentTemplate>
                <bp:Button Text="Edit"
                           Click="{command: _parent.Orders.RowEditOptions.EditRowId = Id}" />
            </ContentTemplate>

Sample 9: Row Decorators

The RowDecorators property can specify decorators that are applied to individual grid rows. The decorator can add properties or event handlers to the <tr> element rendered by the grid.

For the rows in the edit mode, the EditRowDecorators are used instead of the default decorator collection.

Similarly, for the rows in the insert mode, the InsertRowDecorators are used.

<bp:GridView DataSource="{value: Customers}"
             InlineEditing="true">
    <RowDecorators>
        <%-- Set different css class for even and odd rows --%>
        <dot:Decorator class="{value: Id % 2 == 0 ? 'even-row' : 'odd-row'}" />
        <%-- Set background color warning for customer without any orders --%>
        <dot:Decorator style="{value: Orders == 0 ? 'background-color: palevioletred !important;' : ''}" />
    </RowDecorators>
    <EditRowDecorators>
        <%-- Set css class for edit row scenario --%>
        <dot:Decorator class="edit-row" />
    </EditRowDecorators>
    <Columns>
        <bp:GridViewTextColumn Value="{value: Id}" 
                               HeaderText="Customer ID" />
        <bp:GridViewTextColumn Value="{value: Name}"
                               HeaderText="Name" />
        <bp:GridViewTextColumn Value="{value: Orders}" 
                               HeaderText="# of orders" />

                           Click="{command: _parent.Customers.RowEditOptions.EditRowId = Id}" />
            </ContentTemplate>
            <EditTemplate></EditTemplate>
        </bp:GridViewTemplateColumn>
    </Columns>
</bp:GridView>

Sample 10: User Settings

The UserSettings property allows to persist the customizations that the user has made to the grid control. This property expects an object of type GridViewUserSettings which stores the widths and visibility of the individual columns.

This object can be JSON-serialized easily and stored in the database, file system or any other data store. When the user customizes anything in the grid, the changes are stored in this object.

Identification of Grid Columns

Since the developer may change the order of the grid columns, add new columns or remove the existing ones, the GridViewUserSettings object doesn't work with column indexes, but uses column names. You can mark each column in the markup with an unique name that will be used in the user settings object. If you rename the property in the viewmodel, or move the column to another place in the grid, the user settings object won't break and will be able to identify the column.

You can provide the name using the ColumnName property. If the name is not specified, the GridView will try to determine the column name from the Value property. In case of the GridViewTemplateColumn which does not have the property, the column index will be used instead.

If you use the UserSettings property, make sure that at least all template columns have the ColumnName property set. Otherwise the user settings may break in the future when the columns are changed by the application developer.

<bp:GridView DataSource="{value: Customers}"
             UserSettings="{value: UserSettings}">
    <Columns>
        <bp:GridViewTextColumn ColumnName="CustomerName"
                               Value="{value: Name}"
                               HeaderText="Name" />

    }

Sample 11: Server Rendering

The control supports also the server-side rendering. In this mode, many functions cannot work since the control is rendered directly in the HTML output.

The server rendering can be turned on using the RenderSettings.Mode property.

This helps especially the search engines to index the contents of the page. Additionally, the server rendering might make the grid load faster in the browser if there are hundreds of rows or more.

You can read more in the Server-Side HTML Generation and SEO chapter.

Sample 12: Filtering

By default, filtering is not enabled on any column.

The filtering option can be turned on using the AllowFiltering property.

To customize where the filters appear, you can use the FilterPlacement property with values Popup, HeaderRow, SeparateHeaderRow and SeparateFooterRow. The default value is Popup.

If you want to define your custom template for filtering, you can specify the FilterTemplate inner element to provide a custom filter UI on every column. Even if the FilterTemplate is provided, it's still necessary set AllowFiltering to true.

In the viewmodel class, you can access filters by FilteringOptions property on your BusinessPackDataSet object. This property stores all currently used filters on GridView.

The LoadFromQueryable method will apply the filters on the IQueryable automatically. If you load the dataset with your own logic, you'll need to inspect the FilteringOptions and build the query appropriately.

<bp:GridView DataSource="{value: Customers}"
             FilterPlacement="SeparateHeaderRow">
    <Columns>
        <bp:GridViewTextColumn Value="{value: Name}"
                               HeaderText="Name"
                               AllowFiltering />

Sample 13: Filtering - Operators

You can specify what filtering operators should be supported for specific types.

These operators can be limited for the whole GridView or for a specific column. Both GridView and all column types have properties BooleanOperators, NumberOperators, StringOperators, EnumOperators and CollectionOperators, each of these will change filtering operators based on the type of the property.

Business Pack comes with a predefined set of operators for each of the operator types. They can be specified in markup with the op prefix. You can also specify DisplayName for each operator in order provide better description from the business perspective.

Possible operators for each type are: - StringOperators - EqualOperator, NotEqualOperator, StartsWithOperator, EndsWithOperator, ContainsOperator - NumberOperators - EqualOperator, NotEqualOperator, GreaterThanOperator, GreaterThanOrEqualOperator, LessThanOperator, LessThanOrEqualOperator - BooleanOperators - TrueOperator, FalseOperator - EnumOperators - EqualOperator, NotEqualOperator - CollectionOperators- ContainsOperator

If your type supports null values you can also use NullOperator and NotNullOperator.

<bp:GridView DataSource="{value: Customers}"
             FilterPlacement="SeparateHeaderRow">
    <!-- This will only allow Starts with and Ends with operators on all columns with string values in them. -->
    <StringOperators>
        <op:StartsWithOperator DisplayName="Starts with" />
        <op:EndsWithOperator DisplayName="Ends with" />
    </StringOperators>
    <!-- This will only allow filtering by true value on all columns with boolean values. -->
    <BooleanOperators>
        <op:TrueOperator DisplayName="Is true" />
    </BooleanOperators>
    <Columns>
        <!-- This column will use filtering operators specified in the GridView StringOperators collection -->
        <bp:GridViewTextColumn Value="{value: Name}"
                               HeaderText="Name"

        <bp:GridViewTextColumn Value="{value: Name}"
                               HeaderText="Name with only Contains operator"
                               AllowFiltering>
            <StringOperators>
                <op:ContainsOperator DisplayName="Contains" />
            </StringOperators>
        </bp:GridViewTextColumn>

        <!-- This columns will use default filtering operators from the NumberOperators collection  -->
        <bp:GridViewTextColumn Value="{value: Orders}"

                                   HeaderText="Has premium support"

Sample 14: Row Selection

GridView supports row selection via adding a special column GridViewRowSelectColumn. This column will render checkbox in each row, which will allow your users to select rows via ticking this checkbox.

The SelectedRows property is bound to the property which contains list of selected rows from the DataSource collection.

To make SelectedRows contains only value of a specific property from DataSource object (like the Id property of the selected objects), you may use the ItemValueBinding property.

<bp:GridView DataSource="{value: Customers}">
    <Columns>
            <bp:GridViewRowSelectColumn SelectedRows="{value: SelectedCustomerIds}" 
                                        ItemValueBinding="{value: Id}" />
            <bp:GridViewTextColumn Value="{value: Id}" 
                                   HeaderText="ID" />
            <bp:GridViewTextColumn Value="{value: Name}" 
                                   HeaderText="Name" />
            <bp:GridViewTextColumn Value="{value: BirthDate}" 
                                   HeaderText="BirthDate" />
    </Columns>
</bp:GridView>

using DotVVM.BusinessPack.Controls;
using DotVVM.Framework.ViewModel;

public class ViewModel : DotvvmViewModelBase
{
    public BusinessPackDataSet<Customer> Customers { get; set; } = new BusinessPackDataSet<Customer>
        {
            PagingOptions = { PageSize = 10 }
        };

    public List<int> SelectedCustomerIds { get; set; } = new List<int>();

    public override Task PreRender()
    {
        if (Customers.IsRefreshRequired)
        {
            Customers.LoadFromQueryable(GetQueryable(15));
        }

        return base.PreRender();
    }

    private IQueryable<Customer> GetQueryable(int size)
    {
        var numbers = new List<Customer>();
        for (var i = 0; i < size; i++)
        {
