Ajax Toolkit with Visual Web Dev 2008 Express not working


I followed the instructions to install the Ajax tool kit as described here:


I can see all the controls in the Toolkit tab on the left - so it *looks* like a successful install.

I can run the Accordian sample from the Samples Web site with no problem. But when I try and create and use an accordian on my own web site I get this error:

     "Could not load file or assembly 'AjaxControlToolkit' or one of its dependencies. The system cannot find the file specified."

 Is is because I am using VWD 2008 Express edition? Anyone else had this problem?

Are you importing the ajaxcontroltoolkit binaries and namespace?

 The best way to ensure that you're doing this is to drag and drop the controls from the toolbox.  It should add AjaxControlToolkit.dll and AjaxControlToolkit.pdb to your bin directory (and possibly some language resources).  Then all you need to do is make sure you have a reference to the assembly at the top of your page, like so:

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="act" %>

Try adding a reference to AjaxControlToolkit.dll in your application. (it should be here, AjaxControlToolkit-Framework3.5\SampleWebSite\Bin)

I suggest add AjaxControlToolkit.dll as reference again. In VS2008 and FrameWork 3.5, please use AjaxControlToolkit 3.5.

If you used Framework2.0, please use AjaxControlToolkit 1.0. If you used Framework3.5, please use AjaxControlToolkit 3.0.

Note for AjaxControlToolkit:

Version 3.0.20229
2008-02-29 release of the AJAX Control Toolkit targets the official release of .NET Framework 3.5 and Visual Studio 2008.

Version 1.0.20229
You can also download the Toolkit for .NET Framework 2.0, ASP.NET AJAX 1.0 and Visual Studio 2005.
Version 3.0.20820
2008-08-20 release of the AJAX Control Toolkit targets the official release of .NET Framework 3.5 SP1 and Visual Studio 2008 SP1.

Ajax Control Toolkit available for Visual Web Developer Express 2008
Is the Ajax Control Toolkit available for Visual Web Developer Express 2008, or is it meant only for the visual studio products only?    Thanks, Ben The toolkit is available for all editions, express or full. You just have to add the reference to the .dll file in your application and all add items to your toolbox. Download the appropriate version and you can view this video for more clues on what to do after that. The main things you need to do are: 1. Download the ajax control toolkit (if you are using 2008, I would say version 3.5 should be good). (http://www.codeplex.com/...

How Do I Use AJAX and AJAX Control Toolkit In Visual Studio 2008 When Targetting .NET 2.0 Framework?

Troubleshoot Web Service; Ajax AutoComplete events do not appear to not fire; Ajax web service appears to not work. .NET
Folks, I had the situation that Ajax AutoComplete events in the web service did not fire after I copied a project out of a folder, renamed it and moved it to a server. The fix was hard to find but easy to solve. I had some web service modules in an ASMX file that provided AutoComplete entries -- i.e., after the user keys in 2 or 3 characters, the list of possible entries with those leading characters is displayed for the user to select. To solve the problem, look at the web service's directive, not the code-behind or the ASMX designer.  Do a right-mouse-click...
