The AsyncFileUpload control did not work in the IE 9.
Comments: The application that was developed in VS 3.5 and Ajax Tool Kit 3.5. AsyncFileUpload control didn't work in the IE 9. Even I tried to have browser compatible. I doesn't work. But I get the browser error specifying "Line: 22 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."
