DataGrid.OnColumnHeaderDragStarted Method (DragStartedEventArgs)

.NET Framework 4.6 and 4.5

Raises the ColumnHeaderDragStarted event.

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

protected internal virtual void OnColumnHeaderDragStarted(
	DragStartedEventArgs e


Type: System.Windows.Controls.Primitives.DragStartedEventArgs

The data for the event.

Raising an event invokes the event handler through a delegate. For more information, see NIB: Raising an Event.

The OnColumnHeaderDragStarted method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors:

When overriding OnColumnHeaderDragStarted in a derived class, be sure to call the base class’s OnColumnHeaderDragStarted method so that registered delegates receive the event.
