DragStartedEventHandler Delegate

DragStartedEventHandler Delegate

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Represents the method that will handle the DragStarted event of a Thumb.

Namespace:  System.Windows.Controls.Primitives
Assembly:  System.Windows (in System.Windows.dll)

public delegate void DragStartedEventHandler(
	Object sender,
	DragStartedEventArgs e


Type: System.Object
The object where the event handler is attached.
Type: System.Windows.Controls.Primitives.DragStartedEventArgs
The event data.

When you create a DragStartedEventHandler 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 DragStartedEventHandler delegate combined with the DragStartedEventArgs class to provide drag started event data for custom controls that have drag events.
