Control.OnLoad Method

Updated: April 2009

Raises the Load event.

Namespace:  System.Web.UI
Assembly:  System.Web (in System.Web.dll)
protected internal virtual void OnLoad(
	EventArgs e
)

Parameters

e
Type: System.EventArgs

The EventArgs object that contains the event data.

ASP.NET calls this method in order 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, you typically call the base control's OnLoad method. If the base control's OnLoad method is not called, subscribers to the event will not be notified.

// Override the OnLoad method to set _text to 
// a default value if it is null. 
protected override void OnLoad(EventArgs e)
{
    base.OnLoad(e);
    if (_text == null)
        _text = "Here is some default text.";
}
