解决方案
尝试使用ToolkitScriptManager而不是ScriptManager。如果仍然无法解决问题，请检查您的Ajax版本或再次将Ajaxtoolkit重新加载到您的工具箱。
它的工作正常。
如果未解决，请指定确切的错误。

解决方案
Try usingToolkitScriptManagerinstead ofScriptManager. If still it does not solve the issue then check with your Ajax version or reload Ajaxtoolkit again to your toolbox.
Its working fine on my side.
Specify exact error in case it is not resolved.
