Form.OnLoad Method

Updated: July 2009

Raises the Load event.

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

protected virtual void OnLoad(
	EventArgs e
)

Parameters

e
Type: System.EventArgs

An EventArgs that contains the event data.

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

The OnLoad 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 OnLoad in a derived class, be sure to call the base class's OnLoad method so that registered delegates receive the event. Failure to call the base class's OnLoad method may result in certain features of the form, such as auto-scaling, to not function properly.
