AjaxControlToolkit requires ASP.NET Ajax 4.0 scrip

问题:

Recently I started working on VS2010 and I am referencing AjaxControlToolkit 4.1.51116.0. I am getting below runtime 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.

I have seen many question floating for same error but the solution suggested is to use 'ToolkitScriptManager' instead of 'ScriptManager' is not working for me. Any help in this context would be greatly appreciated.

回答1:

Make sure you replace the <asp:ScriptManager /> tag with the namespace of your AjaxControlToolkit assembly (e.g. atk): <atk:ToolkitScriptManager />. That worked for me.
