This method is primarily for use by control developers. Call the RegisterScriptControl<TScriptControl> method from a custom ASP.NET Ajax script control during its onInit event handler to register that control with the page. An ASP.NET Ajax script control must be registered to participate in partial-page rendering.
The RegisterScriptControl<TScriptControl> method adds the specified extender control to an internal list of script controls that is processed during the PreRender event.
