I have recently been having some trouble with the the radControls for ASP.NET.
They were working fine and everything was ok until I randomly started getting this error on every page in my webapp.
The base class includes the field 'RadScriptManager1', but its type (Telerik.Web.UI.RadScriptManager) is not compatible with the type of control (Telerik.Web.UI.RadScriptManager).
i've gone as far as removing rad controls from the GAC, uninstalling and reinstalling them to no avail.
In the code view, there is no error for the scriptmanager, however the RadDatePicker shows an error that is the following
"Warning 1 C:\Projects\ProjectName\Secure\OrderHistory.aspx: ASP.NET runtime error: The base class includes the field 'BeginDate', but its type (Telerik.Web.UI.RadDatePicker) is not compatible with the type of control (Telerik.Web.UI.RadDatePicker). C:\Projects\ProjectNameSecure\OrderHistory.aspx 35 1 ProjectName
Whats even more interesting is the fact that the production test of this website (which is online on our server) works with no problems.
I haven't changed anything with the references or done anything to the controls on the page. This project is under source control and even after I had gotten the restore for it, the problem persists.
Any insight would be greatly appreciated, thanks!
