    ConfirmationBehavior.Command Property

    Gets or sets the command that runs if the user accepts the confirmation message. This is a dependency property.

    Namespace: DevExpress.Mvvm.UI

    Assembly: DevExpress.Xpf.Core.v25.1.dll

    NuGet Package: DevExpress.Wpf.Core

    #Declaration

    public ICommand Command { get; set; }

    #Property Value

    Type Default Description
    ICommand null

    The associated control’s Command property.

    #Remarks

    The following code sample attaches a command to a Button and enables a confirmation message for this command:

    <Button Content="Close">
        <dxmvvm:Interaction.Behaviors>
            <dxmvvm:ConfirmationBehavior EnableConfirmationMessage="{Binding IsSaved, Converter={StaticResource BooleanNegationConverter}}" 
                                         Command="{Binding CloseCommand}" MessageText="The document has unsaved changes. Do you want to close the document?"/>
        </dxmvvm:Interaction.Behaviors>
    </Button>
    
    using DevExpress.Mvvm;
    using DevExpress.Mvvm.DataAnnotations;
    // ...
        public class MainViewModel : ViewModelBase {
        // ...
            [Command]
            public void Close() {
            // ...
            }
        }
    

    If a control does not have a Command property, you can use the CommandPropertyName property to attach the behavior to the command.
