ListGroup

in namespace DotVVM.Framework.Controls.Bootstrap4

Renders a Bootstrap list group of items, links or buttons.

Usage & Scenarios

Renders a Bootstrap list group of items, links or buttons.

https://getbootstrap.com/docs/4.3/components/list-group/

Sample 1: Basic ListGroup

Each item inside the ListGroup is represented by the ListGroupItem control.

Place the items inside the ListGroup.

page.dothtml
ViewModel.cs

<bs:ListGroup>
  <bs:ListGroupItem Text="{value: Text}" />
  <bs:ListGroupItem Text="Item 2" />
  <bs:ListGroupItem Text="Item 3" />
  <bs:ListGroupItem>
    <h3>Custom content</h3>
    <p>Custom list item content</p>
  </bs:ListGroupItem>
</bs:ListGroup>

using DotVVM.Framework.ViewModel;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace DotvvmWeb.Views.Docs.Controls.bootstrap.ListGroup.sample1
{
    public class ViewModel : DotvvmViewModelBase
    {
        public string Text { get; set; } = "Data-bound text of the item.";
    }
}

Sample 2: ListGroup - Item types

The ListGroup control has the ItemType property which specified the type of list group items - Default, Link and Button.

page.dothtml
ViewModel.cs

<bs:ListGroup ItemType="Button">
  <bs:ListGroupItem Text="Item 1" />
  <bs:ListGroupItem Text="Item 2" Color="Primary" />
  <bs:ListGroupItem Text="Item 3" Color="Info" />
  <bs:ListGroupItem Text="{value: Text}" Color="Success" />
  <bs:ListGroupItem Text="Item 5" Color="Warning" />
  <bs:ListGroupItem Text="Item 6" Color="Danger" />
</bs:ListGroup>

using DotVVM.Framework.ViewModel;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace DotvvmWeb.Views.Docs.Controls.bootstrap.ListGroup.sample2
{
    public class ViewModel : DotvvmViewModelBase
    {
        public string Text { get; set; } = "This is sample text.";
    }
}

Sample 3: Data-binding

The DataSource property can be used to generate the items from an IEnumerable in the viewmodel.

Then you can use the following properties which tell the control what property of the collection item will be used:

TextBinding specifies the property of the collection elements to be used as list item text.
ColorBinding specifies the property of the collection elements to be used as list item color.
NavigateUrlBinding specifies the property of the collection elements to be used as list item link URL.
IsEnabledBinding specifies the property of the collection elements indicating whether the list item is enabled or not.
IsSelectedBinding specifies the property of the collection elements indicating whether the list item is active or not.
ClickBinding specifies a command in the viewmodel to be called when the list item is clicked.

page.dothtml
ViewModel.cs

<bs:ListGroup ItemType="Link" 
              DataSource="{value: LinksDataSet}" 
              IsEnabledBinding="{value: IsEnabled}" 
              IsSelectedBinding="{value: IsSelected}" 
              TextBinding="{value: Text}" 
              ColorBinding="{value: Color}" 
              NavigateUrlBinding="{value: NavigateUrl}" />

public class ViewModel : DotvvmViewModelBase
{
    public List<LinkItem> LinksDataSet => new List<LinkItem>()
    {
        new LinkItem() { IsEnabled = true, IsSelected = false, NavigateUrl = "https://www.google.com/", Text = "Google", Color = BootstrapColor.Info },
        new LinkItem() { IsEnabled = true, IsSelected = false, NavigateUrl = "http://www.w3schools.com/html/", Text = "W3Schools", Color = BootstrapColor.Success },
        new LinkItem() { IsEnabled = true, IsSelected = true, NavigateUrl = "https://www.microsoft.com/en-us/", Text = "Microsoft", Color = BootstrapColor.Warning },
        new LinkItem() { IsEnabled = false, IsSelected = false, NavigateUrl = "https://github.com/riganti/dotvvm", Text = "DotVVM Github", Color = BootstrapColor.Danger }
    };
    
}

public class LinkItem
{
    public string Text { get; set; }
    public string NavigateUrl { get; set; }
    public bool IsSelected { get; set; }
    public bool IsEnabled { get; set; }
    public BootstrapColor Color { get; set; }

}

Sample 4: Data-binding

The ClickBinding property can be used when the list group contains the buttons.

page.dothtml
ViewModel.cs

<bs:ListGroup ItemType="Button" 
              DataSource="{value: Values}" 
              TextBinding="{value: _this}" 
              ClickBinding="{command: _parent.Select(_this)}" />

Selected item: {{value: SelectedValue}}

using DotVVM.Framework.Controls.Bootstrap4;
using DotVVM.Framework.ViewModel;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace DotvvmWeb.Views.Docs.Controls.bootstrap.ListGroup.sample4
{
    public class ViewModel : DotvvmViewModelBase
    {
        public List<string> Values => new List<string>() { "one", "two", "three" };

        public string SelectedValue { get; set; }
        
        
        public void Select(string value)
        {
            SelectedValue = value;
        }
    }
    
}

Sample 5: Badges

The list items can contain Badge controls. USe the Badge inner element property to specify the badge contents.

page.dothtml
ViewModel.cs

<bs:ListGroup>
  <bs:ListGroupItem Text="{value: Text}">
    <Badge>
      <bs:Badge>10</bs:Badge>
    </Badge>
  </bs:ListGroupItem>
  <bs:ListGroupItem Text="Item 2">
    <Badge>
      <bs:Badge>2</bs:Badge>
    </Badge>
  </bs:ListGroupItem>
</bs:ListGroup>

using DotVVM.Framework.ViewModel;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace DotvvmWeb.Views.Docs.Controls.bootstrap.ListGroup.sample1
{
    public class ViewModel : DotvvmViewModelBase
    {
        public string Text { get; set; } = "Data-bound text of the item.";
    }
}

Sample 6: Flush mode

The IsFlush property can be used to render the list group without borders to render the list group items edge-to-edge in a parent container.

Flush mode cannot be combined with horizontal ListGroup

page.dothtml
ViewModel.cs

<bs:ListGroup IsFlush="true">
  <bs:ListGroupItem Text="{value: Text}" />
  <bs:ListGroupItem Text="Item 2" />
  <bs:ListGroupItem Text="Item 3" />
  <bs:ListGroupItem Text="Item 4" />
</bs:ListGroup>

using DotVVM.Framework.ViewModel;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace DotvvmWeb.Views.Docs.Controls.bootstrap.ListGroup.sample1
{
    public class ViewModel : DotvvmViewModelBase
    {
        public string Text { get; set; } = "Data-bound text of the item.";
    }
}

Sample 7: Type and responsibility

The Type property controls whether the ListGroup would be Horizontal or Vertical.

When using Horizontal ListGroup, than we can also use MaximumScreenSizeBeforeChangeToVertical to set when the ListGroup should change from Horizontal to Vertical.
If set to None than the ListGroup will never change to Vertical.

page.dothtml
ViewModel.cs

<bs:ListGroup Type="Horizontal" MaximumScreenSizeBeforeChangeToVertical="Medium" >
  <bs:ListGroupItem Text="{value: Text}" />
  <bs:ListGroupItem Text="Item 2" />
  <bs:ListGroupItem Text="Item 3" />
  <bs:ListGroupItem Text="Item 4" />
</bs:ListGroup>

using DotVVM.Framework.ViewModel;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace DotvvmWeb.Views.Docs.Controls.bootstrap.ListGroup.sample1
{
    public class ViewModel : DotvvmViewModelBase
    {
        public string Text { get; set; } = "Data-bound text of the item.";
    }
}
