Two things to check. Before you try to open anything thing in the designer, rebuild your project first. Check the references for the Grid and Shared DLLs. If you have them set to Copy Local true, then make sure the versions of these DLL''s in your GAC are the same as the copy local versions. The designer will try to load the versions in the GAC, but the exe will try to use the local copies. If these are different versions, then you can have problems like this.

We have our refernces set to Copy Local true. All of the versions match - the versions in our references in the app are 3.0.1.0 and the versions in our gac (C:\WINDOWS\assembly) are 3.0.1.0. Is there anything else for us to check? >Two things to check. > >Before you try to open anything thing in the designer, rebuild your project first. > >Check the references for the Grid and Shared DLLs.

You can try removing the Essential Grid controls from your toolbox and then re-add them from the GAC. If you set Copy Local = false and remove the local copies so only the GAC is accessed, then I think the problem may go away.
