Type: SystemEventArgs

The EventArgs object that contains the event data.


ASP.NET calls this method to raise the Load event. If you are developing a custom control, you can override this method in order to provide additional processing. If you override this method, call the base control's OnLoad method to notify subscribers to the event.

Protected Overrides Sub OnLoad(ByVal e As EventArgs)
    If _text Is Nothing Then
        _text = "Here is some default text." 
    End If 
End Sub
// Override the OnLoad method to set _text to 
// a default value if it is null. 
protected override void OnLoad(EventArgs e)
    if (_text == null)
        _text = "Here is some default text.";
