This method is primarily for use by control developers. Call the [M:System.Web.UI.ScriptManager.RegisterExtenderControl``1(``0,System.Web.UI.Control)l] method from a custom ASP.NET AJAX extender control during its onInit event handler to register that control with the page. An ASP.NET AJAX extender control must be registered to participate in partial-page rendering.
The RegisterExtenderControl<TExtenderControl> method adds the specified extender control to an internal list of extender controls and the target script controls they extend. This list is processed during the PreRender event.
