I had installed ajax tool kit with Vs 4.0 version. then i added script manager and update panel in my master page. but when i add new ajax control which shows following error...
Microsoft JScript runtime error: AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the ToolkitScriptManager in AjaxControlToolkit.dll.
