Raises events for the System.Web.UI.WebControls.ImageButton control when it posts back to the server.
The ImageButton.RaisePostBackEvent(string) member is used primarily by control developers when deriving a custom class from the System.Web.UI.WebControls.ImageButton control.
This method is used internally by the System.Web.UI.WebControls.ImageButton control, when it is clicked, to raise a ImageButton.Click event and, if defined, a ImageButton.Command event.
