OnUnload Method

Control.OnUnload Method (EventArgs)


Raises the Unload event.

Namespace:   System.Web.UI
Assembly:  System.Web (in System.Web.dll)

protected internal virtual void OnUnload(
	EventArgs e


Type: System.EventArgs

An EventArgs object that contains event data.

ASP.NET calls this method to raise the Unload 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 OnUnload method to notify subscribers to the event.

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