    I have a page with a telerik:RadScriptManager.  According to a profiler I'm using, in a single page load Telerik.Web.UI.RadScriptManager.OnResolveScriptReference() is called 16,949 times and accounts for a half second of my page load times.  I added my own handler for ResolveScriptReference and it does seem to be called quite a lot.  The Scripts collection has 7 scripts.  In my own handler, I can see that it's resolving the same scripts over and over: Telerik.Web.UI.Common.Core.js, Telerik.Web.UI.Common.jQuery.js, etc.

    This project using Telerik.Web.UI.DLL 2011.1.519.40.  I know that's an older version, I'm not sure i can get authorized to upgrade it (due to a fear of breaking something else).  I'm hoping there is some problem in the way this control is being used that I can alter in order to fix the problem, but I don't even know where to start.

    Hi Matthew,

    In general the OnResolveScriptReference method is called by the OnPreRender event handler for each script reference in the Scripts collection of the ScriptManger, which make it quite unusuall to be executed 16,949 times as it's in your case. In order to resolve this issue, please try to provide a sample page which I could test with the latest version of our controls.
