OnTabSelecting Method

Raises the TabSelecting event.

Syntax

Visual Basic

'Declaration
 
Protected Overridable Sub OnTabSelecting( _
   ByVal e As CancelableMdiTabEventArgs _
) 

C#

protected virtual void OnTabSelecting( 
   CancelableMdiTabEventArgs e
)

Parameters

e

A CancelableMdiTabEventArgs that provides data for the event.

Remarks

Raising an event invokes the event handler through a delegate.

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