OnBeforeSplitterDrag Method

Raises the BeforeSplitterDrag event before a splitter bar is repositioned.

Syntax

Visual Basic

'Declaration
 
Protected Overridable Sub OnBeforeSplitterDrag( _
   ByVal e As CancelablePanesEventArgs _
) 

C#

protected virtual void OnBeforeSplitterDrag( 
   CancelablePanesEventArgs e
)

Parameters

e

A CancelablePanesEventArgs that provides data for the event.

Remarks

Raising an event invokes the event handler through a delegate.

The OnBeforeSplitterDrag 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 OnBeforeSplitterDrag in a derived class, be sure to call the base class's OnBeforeSplitterDrag method so that registered delegates receive the event.
