DialogController.Accepting Event

Occurs when executing the current Dialog Controller’s DialogController.AcceptAction.

Namespace: DevExpress.ExpressApp.SystemModule

Assembly: DevExpress.ExpressApp.v24.2.dll

NuGet Package: DevExpress.ExpressApp

Declaration

C#

public event EventHandler<DialogControllerAcceptingEventArgs> Accepting

VB.NET

Public Event Accepting As EventHandler(Of DialogControllerAcceptingEventArgs)

Event Data

The Accepting event's data class is DialogControllerAcceptingEventArgs. The following properties provide information specific to this event:

Property	Description
AcceptActionArgs	Arguments passed to the DialogController.AcceptAction‘s Execute event.
Cancel	Gets or sets a value indicating whether the event should be canceled. Inherited from CancelEventArgs.
ShowViewParameters	Provides access to the ShowViewParameters object used to specify a View to be displayed after executing the DialogController.Accepting event.

Remarks

Executing the Action specified by the Dialog Controller’s DialogController.AcceptAction property results in the following, by default:

• The current Window contains a Detail View:

  The Save Action of the current Window’s ModificationsController is executed, and the Window is closed.

• The current Window contains a List View:

  The current Window is closed.

Handle the Accepting event to perform custom actions before the default actions defined above are executed. To cancel executing the default actions, set the handler’s DialogControllerAcceptingEventArgs.Cancel parameter to true (by default, it is set to false).

If you need to cancel execution of either the Save Action or closing the current pop-up Window (see above), use the DialogController.SaveOnAccept and DialogController.CanCloseWindow properties.

Note

The Action specified by the DialogController.AcceptAction property is executed both when pressing the pop-up Window’s accept button and when double-clicking an object selected in the Window’s List View.
