Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)

Protected Overridable Sub OnDeselecting ( _
	e As TabControlCancelEventArgs _
)

protected virtual void OnDeselecting(
	TabControlCancelEventArgs e
)

protected:
virtual void OnDeselecting(
	TabControlCancelEventArgs^ e
)

abstract OnDeselecting : 
        e:TabControlCancelEventArgs -> unit 
override OnDeselecting : 
        e:TabControlCancelEventArgs -> unit

Parameters

e: Type: System.Windows.Forms..::.TabControlCancelEventArgs
A TabControlCancelEventArgs that contains the event data.

Remarks

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

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