Form..::.OnDeactivate Method

Raises the Deactivate event.

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

Syntax

Visual Basic

Protected Overridable Sub OnDeactivate ( _
    e As EventArgs _
)

protected virtual void OnDeactivate(
    EventArgs e
)

Visual C++

protected:
virtual void OnDeactivate(
    EventArgs^ e
)

abstract OnDeactivate : 
        e:EventArgs -> unit 
override OnDeactivate : 
        e:EventArgs -> unit

Parameters

e: Type: System..::.EventArgs
The EventArgs that contains the event data.

Remarks

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

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