Control..::.OnLayout Method

Raises the Layout event.

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

Syntax

Visual Basic

Protected Overridable Sub OnLayout ( _
    levent As LayoutEventArgs _
)

protected virtual void OnLayout(
    LayoutEventArgs levent
)

Visual C++

protected:
virtual void OnLayout(
    LayoutEventArgs^ levent
)

abstract OnLayout : 
        levent:LayoutEventArgs -> unit 
override OnLayout : 
        levent:LayoutEventArgs -> unit

Parameters

levent: Type: System.Windows.Forms..::.LayoutEventArgs
A LayoutEventArgs that contains the event data.

Remarks

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

The OnLayout 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 OnLayout in a derived class, be sure to call the base class's OnLayout method so that registered delegates receive the event and for typical docking and anchoring functions to work. Derived classes should override this method to do any custom layout logic.
