DataGrid.OnColumnHeaderDragDelta(DragDeltaEventArgs) Method

Definition

Raises the ColumnHeaderDragDelta event.

protected public:
 virtual void OnColumnHeaderDragDelta(System::Windows::Controls::Primitives::DragDeltaEventArgs ^ e);
protected internal virtual void OnColumnHeaderDragDelta (System.Windows.Controls.Primitives.DragDeltaEventArgs e);
abstract member OnColumnHeaderDragDelta : System.Windows.Controls.Primitives.DragDeltaEventArgs -> unit
override this.OnColumnHeaderDragDelta : System.Windows.Controls.Primitives.DragDeltaEventArgs -> unit
Protected Friend Overridable Sub OnColumnHeaderDragDelta (e As DragDeltaEventArgs)

Parameters

e
DragDeltaEventArgs

The data for the event.

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnColumnHeaderDragDelta 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 OnColumnHeaderDragDelta(DragDeltaEventArgs) in a derived class, be sure to call the base class' OnColumnHeaderDragDelta(DragDeltaEventArgs) method so that registered delegates receive the event.
