DeleteOccurrenceWindowShowingEventHandler Delegate

A method that handles the SchedulerControl.DeleteOccurrenceWindowShowing event.

Namespace:DevExpress.Xpf.Scheduling
Assembly:DevExpress.Xpf.Scheduling.v19.1.dll

Expanded Syntax

Parameters

sender
Type: Object
The event source. This parameter identifies the SchedulerControl control which raised the event.
e
Type: DeleteOccurrenceWindowShowingEventArgs
A DeleteOccurrenceWindowShowingEventArgs object which contains event data.

Expanded Remarks

When creating a DeleteOccurrenceWindowShowingEventHandler delegate, you identify the method that will handle the corresponding event. To associate an event with your event handler, add a delegate instance to this event. The event handler is called whenever the event occurs unless you remove the delegate. For more information about event handler delegates, see Events and Delegates in MSDN.
