ScriptManager Classes

Listing 1. The ScriptManager control manages scripts that are used in an ASP.NET AJAX-enabled Web page. It relies on several other classes that work behind the scenes, such as ScriptResourceHandler, to access scripts. (Portions of the script URLs shown here have been removed for brevity.)

   Sys.WebForms.PageRequestManager._initialize('ScriptManager1',    
      document.getElementById('form1'));
   Sys.WebForms.PageRequestManager.getInstance()._updateControls([], 
      [], [], 90);
