Assembly: System.Windows (in System.Windows.dll)
- Type: System.Object
The object where the event handler is attached.
- Type: System.Windows.Controls.Primitives.DragDeltaEventArgs
The event data.
When you create a delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate.
You can also use the combined with the DragDeltaEventArgs class to provide drag delta event data for custom controls that have drag events.
