Assembly : DevExpress.Xpf.Core.v25.2.dll

Declaration

C#
VB.NET

csharp

public string CommandPropertyName { get; set; }

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:
