When you register a script file with this method, the script is rendered every time that an asynchronous postback occurs. To register a script file for a control that is inside an UpdatePanel control so that script is registered only when the UpdatePanel control is updated, use the RegisterClientScriptInclude(Control^, Type^, String^, String^) overload of this method.
If you want to register a script block that does not pertain to partial-page updates, and if you want to register the script block only one time during initial page rendering, use the RegisterClientScriptBlock method of the ClientScriptManager class. You can get a reference to the ClientScriptManager object from the ClientScript property of the page.
