Hi there, i am developing an asp.net website and i wanted to use ajax controls with it but when i use the 'ScripManager' get the following error message when i debug my application:

ScriptManager throw new 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.");

But when i use the 'ToolkitScriptManager', i get the following error message:

Server Error in '/AjaxControlToolkitSampleSite' Application. -------------------------------------------------------------------------------- Could not load type 'System.Web.UI.ScriptReferenceBase' from assembly 'System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.

First, are you using the Script Manager from the toolkit, not the one on the Ajax Extensions tab in the toolbox? (It's what the error is telling you).

Second, you've probably downloaded the wrong version of the library. Try this: Ajax Control Toolkit[^] and get: AjaxControlToolkit.Binary.NET4.zip

Hi,

I think 90% of ur problem is with ur AjaxControlToolKit version u r using.

If u r using VS-2010, then use the " AjaxControlToolkit.Binary.NET4" version of toolkit and it doesnt matter ScriptManager from which u r taking either from "AjaxExtensions" or from "AjaxToolkit".

If u r using VS-2008 then u can use "AjaxControlToolkit 3.0" version.

Solution 3

check if you are using the correct version of AjaxControlToolkit dll file. make sure that the ajax assembly file information is correct in web.config file or try manually entering the register ajaxcontroltool kit directive and adding the control to aspx page.
