public event EventHandler<DialogControllerAcceptingEventArgs> Accepting
Public Event Accepting As EventHandler(Of DialogControllerAcceptingEventArgs)
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. |
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 current Window contains a List View:
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.
The following code snippets (auto-collected from DevExpress Examples) contain references to the Accepting event.
