DependencyPropertyBehavior Class

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

Namespace: DevExpress.Mvvm.UI

Assembly: DevExpress.Xpf.Core.v22.2.dll

NuGet Package: DevExpress.Wpf.Core

Declaration

public class DependencyPropertyBehavior :
    Behavior<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:

<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>
using DevExpress.Mvvm;

namespace Example.ViewModel {
    public class MainViewModel : ViewModelBase {
        public virtual string SelectedTextBoxText { get; set; }
    }
}
