CompositeCommandBehavior.CommandPropertyName Property

Gets or sets the name of the associated control‘s ICommand property. This is a dependency property.

Namespace: DevExpress.Mvvm.UI

Assembly: DevExpress.Xpf.Core.v21.2.dll

NuGet Package: DevExpress.Wpf.Core

Declaration

C#

public string CommandPropertyName { get; set; }

VB.NET

Public Property CommandPropertyName As String

Property Value

Type	Default	Description
String	Command	The name of the ICommand property.

Remarks

If the associated control does not have a Command property, assign the CommandPropertyName property to the name of an ICommand property. The behavior binds its CompositeCommand to the specified property.

The following code sample executes a CompositeCommand when a user clicks the ThemedWindow‘s back button:

MainWindow.xaml

<dx:ThemedWindow ...
    xmlns:dx="http://schemas.devexpress.com/winfx/2008/xaml/core"
    xmlns:ViewModels="clr-namespace:CompositeCommandCommandPropertyName.ViewModels"
    xmlns:dxmvvm="http://schemas.devexpress.com/winfx/2008/xaml/mvvm"
    ShowBackButton="True">
    <dx:ThemedWindow.DataContext>
        <ViewModels:MainViewModel/>
    </dx:ThemedWindow.DataContext>
    <dxmvvm:Interaction.Behaviors>
        <dxmvvm:CompositeCommandBehavior CommandPropertyName="NavigateBackCommand">
            <dxmvvm:CommandItem Command="{Binding SaveCommand}"/>
            <dxmvvm:CommandItem Command="{Binding CloseCommand}"/>
        </dxmvvm:CompositeCommandBehavior>
    </dxmvvm:Interaction.Behaviors>
    <!-- ... -->
