TextBoxFormGroup
in namespace DotVVM.Framework.Controls.Bootstrap4
Renders a FormGroup control with a TextBox
Usage & Scenarios
Represents a TextBox in FormGroup.
Sample 1: Basic Text Box Form Group
The TextBoxFormGroup 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:TextBoxFormGroup LabelText="Static label" Text="Static value" />
<bs:TextBoxFormGroup LabelText="{value: LabelText}" Text="{value: ValueText}" />
</bs:Form>using DotVVM.Framework.ViewModel;
namespace DotvvmWeb.Views.Docs.Controls.bootstrap4.TextBoxFormGroup.sample1
{
public class ViewModel : DotvvmViewModelBase
{
public string LabelText { get; set; } = "Bound label";
public string ValueText { get; set; } = "Bound value";
}
}Sample 2: Text Box Form Group - Enabled and Visible
The Enabled property is used to enable / disable the TextBoxFormGroup control.
It is also possible to show / hide the TextBoxFormGroup control with the Visible property.
<bs:Form>
<bs:TextBoxFormGroup LabelText="Label" Text="Enabled textbox" Enabled="true" />
<bs:TextBoxFormGroup LabelText="Label" Text="Disabled textbox" Enabled="false" />
<bs:TextBoxFormGroup LabelText="Label" Text="Visible textbox" Visible="{value: TrueValue}" />
<bs:TextBoxFormGroup LabelText="Label" Text="Invisible textbox" Visible="{value: FalseValue}" />
</bs:Form>using DotVVM.Framework.ViewModel;
namespace DotvvmWeb.Views.Docs.Controls.bootstrap4.TextBoxFormGroup.sample2
{
public class ViewModel : DotvvmViewModelBase
{
public bool TrueValue { get; set; } = true;
public bool FalseValue { get; set; } = false;
}
}Sample 3: Text Box Form Group - Format String
The content of TextBox can be formatted with the FormatString property if needed.
<bs:Form>
<bs:TextBoxFormGroup LabelText="Formatting string" Text="{value: NumberValue}" FormatString="#0.00" />
</bs:Form>using DotVVM.Framework.ViewModel;
namespace DotvvmWeb.Views.Docs.Controls.bootstrap4.TextBoxFormGroup.sample3
{
public class ViewModel : DotvvmViewModelBase
{
public double NumberValue { get; set; } = 123.456789;
}
}Sample 4: Text Box Form Group - Type and ValueType
The TextBoxType property is used to change the mode of the text field. Possible values are:
NormalPasswordMultiLineTelephoneUrlEmailDateTimeColorSearchNumber
<bs:Form>
<bs:TextBoxFormGroup LabelText="Password box" Text="password" TextBoxType="Password" />
</bs:Form> Sample 5: Text Box Form 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:TextBoxFormGroup LabelText="Update test" Text="{value: UpdateTestText}" UpdateTextAfterKeydown="true" />
<span>{{value: UpdateTestText}}</span>
<bs:TextBoxFormGroup LabelText="OnChanged test" Text="{value: ChangedTestText}" Changed="{command: Changed()}" />
<span>{{value: ChangedValue}}</span>
</bs:Form>using DotVVM.Framework.ViewModel;
namespace DotvvmWeb.Views.Docs.Controls.bootstrap4.TextBoxFormGroup.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;
}
}
