Ajax Control Toolkit - Toolscriptmanager not available

I've been trying to get this asp.net 2.0 application up and running with little success. I removed all references and added the ajax control toolkit again and I'm still getting "ToolScriptManager:ID property not specified".

Any help? Screenshot included.

Thanks!

From stackoverflow

• Check the AjaxControlToolkit reference in your project. If the AjaxControlToolkit is not in the Global Assembly Cache (C:\Windows\assembly), you have to set the "Copy local" property. Then the dll will be copied to the binary folder where it is needed during the execution of your web site/web app.

• Hmm, so even though the dll shows in the bin folder as you can see in the screen shot it may not be available to the website?

  Thanks
