DependencyPropertyBehavior Class

Allows you to bind a ViewModel property to a control’s non-dependency property.

Assembly: DevExpress.Xpf.Core.v21.1.dll

Declaration

C#
VB.NET

public class DependencyPropertyBehavior :
    Behavior<DependencyObject>

Public Class DependencyPropertyBehavior
    Inherits Behavior(Of DependencyObject)

Remarks

To bind a ViewModel property to a control’s non-dependency property, specify the following DependencyPropertyBehavior properties:

Property	Description
Binding	Gets or sets the binding that should be applied to the specified property. This is a dependency property.
EventName	Gets or sets the name of the event the DependencyPropertyBehavior handles to update the binding.
PropertyName	Gets or sets a control’s property name (the binding’s target).

The following code sample binds the ViewModel’s SelectedTextBoxText property to the TextBox.SelectedText non-dependency property:

MainView.xaml

<UserControl x:Class="Example.View.MainView"
<!-- ... -->
    xmlns:dxmvvm="http://schemas.devexpress.com/winfx/2008/xaml/mvvm"
    <!-- ... -->
        <StackPanel Orientation="Horizontal" VerticalAlignment="Top">
            <!--The TextBox.SelectedText property is not a dependency property-->
            <TextBox Width="200" Text="Select some text in this box">
                <dxmvvm:Interaction.Behaviors>
                    <dxmvvm:DependencyPropertyBehavior PropertyName="SelectedText" EventName="SelectionChanged" Binding="{Binding SelectedTextBoxText, Mode=TwoWay}"/>
                </dxmvvm:Interaction.Behaviors>
            </TextBox>
            <TextBox Width="200" Text="{Binding SelectedTextBoxText}" IsReadOnly="True"/>
        </StackPanel>
        <!-- ... -->
</UserControl>
