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.v24.1.dll

NuGet Package: DevExpress.Wpf.Core

Declaration

public string CommandPropertyName { get; set; }

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:

                MessageText="Do you want to navigate back?" CommandPropertyName="NavigateBackCommand">
