ConfirmationBehavior.CommandPropertyName Property

Gets or sets a name of an associated control’s command property. This is a dependency property.

Namespace: DevExpress.Mvvm.UI

Assembly: DevExpress.Xpf.Core.v23.2.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 property that should invoke the confirmation message box.

Remarks

Note that many controls have a Command property. If the command should trigger ConfirmationBehavior, then you do not need to specify CommandPropertyName.

When a user triggers a command you specified in CommandPropertyName, the control first displays a confirmation message. If a user confirms the operation, the ConfirmationBehavior executes the command specified by the Command property.

The following code sample specifies the CommandPropertyName property and enables a confirmation message when a user clicks the ThemedWindow‘s back button. If a user confirms the operation, the ConfirmationBehavior executes the Close command:

        <dxmvvm:ConfirmationBehavior Command="{Binding CloseCommand}"
                MessageText="Do you want to navigate back?" CommandPropertyName="NavigateBackCommand">
