I created a web application using 2.0 and AJAX 1.0 a couple months ago. All was running fine and a published copy is being reviewed by users on a testserver. However, I just opened the project in VS 2005 and the AJAX tools were no longer in the toolbox. I reinstalled however I do not see all of the controls in the Toolbox. When I build the application I get two errors for each control. One indicates that the control is "not an known element. This can occur if there is a compilation error in the Web site." The second is a compiler error: "Request for the permission of type 'System.WEb.AspNetHostingPermission, System, Version=126.96.36.199, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I get this pair of errors for each AJAX contol on the form.
I can see the PublicKeyToken in the config file:
<add assembly="System.Windows.Forms, Version=188.8.131.52, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
I think I am missing something in the reinstallation of AJAX Toolkit
Anyone have an idea where to go from here?
I found that a .dll was missing and that cleared the first error but still get the permissions error referenced above. The .dll was the following:
C:\Program Files\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\AjaxControlsToolkit\Binaries\AjaxControlToolkit.dll
