UserControl..::.OnLoad Method

Raises the Load event.

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

Syntax

Visual Basic (Declaration)

Protected Overridable Sub OnLoad ( _
    e As EventArgs _
)

Visual Basic (Usage)

Dim e As EventArgs

Me.OnLoad(e)

protected virtual void OnLoad(
    EventArgs e
)

Visual C++

protected:
virtual void OnLoad(
    EventArgs^ e
)

JScript

protected function OnLoad(
    e : EventArgs
)

Parameters

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

Remarks

The Load event occurs after the control is created, but before the control becomes visible for the first time.

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.
