I"m on Sitefinity 5.0 and Visual Studio 2010. I just installed the RadControls for ASP.NET AJAX for VS and I am trying to create a calendar widget with the RadScheduler control. When I drag the RadScheduler onto my Webcontrol ascx page I get an assembly error (listed below, and attached as a picture of the exact error). If I even try to run Sitefinity from here it completely crashes and I have to use the file recovery to revert back to a previous version to get the site running again.
"C:\Program Files(x86)\Telerik\Service Desk\Custom\Widgets\EventsCalendar.ascx: ASP.NET runtime error: Could not load file or assembly 'Telerik.Web.UI, Version=2012.1.215.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HResult:0x80131040)"
The current version of my Telerik.Web.UI dll file is 2012.3.1016.40, and my runtime version is v4.0.30319.
I've tried rolling back the Telerik.Web.UI to an earlier version, 2012.1.215.35, but still got the same error. I don't have and can't find any other dll for version 2012.3.1016.40.
I've seen some other threads, not on the Sitefinity site, but on the Telerik forums for this error where someone said you could reference a different version in the assembly/web.config file but I was't quite sure how to do that. Also I am wondering if there is a possibility that this version of the RadControls aren't supported with Sitefinity 5.0?
Like many other users I am also a beginner and new to the developing world so any feedback in laymens terms would be appreciated. Thanks
