TextBoxGroup
in namespace DotVVM.Framework.Controls.Bootstrap
Represents a group of Label and TextBox in the Form control.
Usage & Scenarios
Represents a group of Label and TextBox in the Form control.
Sample 1: Basic Text Box Group
The TextBoxGroup control has the LabelText property for the label and the Text property for text inside the text field.
Both these properties can also be bound to properties in viewmodel.
<bs:Form>
<bs:TextBoxGroup LabelText="Static label" Text="Static value" />
<bs:TextBoxGroup LabelText="{value: LabelText}" Text="{value: ValueText}" />
<bs:TextBoxGroup LabelText="No value" />
</bs:Form>using DotVVM.Framework.ViewModel;
namespace DotvvmWeb.Views.Docs.Controls.bootstrap.TextBoxGroup.sample1
{
public class ViewModel : DotvvmViewModelBase
{
public string LabelText { get; set; } = "Data-bound label";
public string ValueText { get; set; } = "Data-bound value";
}
}Sample 2: Text Box Group - Enabled and Visible
The Enabled property is used to enable / disable the TextBoxGroup control.
It is also possible to show / hide the TextBoxGroup control with the Visible property.
<bs:Form>
<bs:TextBoxGroup LabelText="Label" Text="Enabled textbox" Enabled="true" />
<bs:TextBoxGroup LabelText="Label" Text="Disabled textbox" Enabled="false" />
<bs:TextBoxGroup LabelText="Label" Text="Visible textbox" Visible="{value: TrueValue}" />
<bs:TextBoxGroup LabelText="Label" Text="Invisible textbox" Visible="{value: FalseValue}" />
</bs:Form>using DotVVM.Framework.ViewModel;
namespace DotvvmWeb.Views.Docs.Controls.bootstrap.TextBoxGroup.sample2
{
public class ViewModel : DotvvmViewModelBase
{
public bool TrueValue { get; set; } = true;
public bool FalseValue { get; set; } = false;
}
}Sample 3: Text Box Group - Format String
The content of TextBox can be formatted with the FormatString property if needed.
<bs:Form>
<bs:TextBoxGroup LabelText="Formatting string" Text="{value: NumberValue}" FormatString="#0.00" />
</bs:Form>using DotVVM.Framework.ViewModel;
namespace DotvvmWeb.Views.Docs.Controls.bootstrap.TextBoxGroup.sample3
{
public class ViewModel : DotvvmViewModelBase
{
public double NumberValue { get; set; } = 123.456789;
}
}Sample 4: Text Box Group - Type and ValueType
The Type property is used to change the mode of the text field. Possible values are:
NormalPasswordMultiLineTelephoneUrlEmailDateTimeColorSearchNumber
The ValueType property is used for changing the type of value being formatted. Possible values are:
TextDateTimeNumber
<bs:Form>
<bs:TextBoxGroup LabelText="Password box" Text="password" Type="Password" />
<bs:TextBoxGroup LabelText="Numeric value" Text="0" ValueType="Number" />
</bs:Form>Sample 5: Text Box Group - UpdateTextAfterKeydown and Changed
If you need property bound to Text property to update after every pressed key just set the UpdateTextAfterKeydown property to true.
With the Changed property it is possible to bind to onchange event and perform specific actions when the value of text field changes.
<bs:Form>
<bs:TextBoxGroup LabelText="Update test" Text="{value: UpdateTestText}" UpdateTextAfterKeydown="true" />
<bs:TextBoxGroup LabelText="OnChanged test" Text="{value: ChangedTestText}" Changed="{command: Changed()}" />
</bs:Form>
<span>{{value: UpdateTestText}}</span>
<br />
<span>{{value: ChangedValue}}</span>using DotVVM.Framework.ViewModel;
namespace DotvvmWeb.Views.Docs.Controls.bootstrap.TextBoxGroup.sample5
{
public class ViewModel : DotvvmViewModelBase
{
public string UpdateTestText { get; set; } = "Change this";
public string ChangedValue { get; set; } = "Not changed";
public string ChangedTestText { get; set; } = "text";
public void Changed()
{
ChangedValue = "Changed to " + ChangedTestText;
}
}
