Hi Mike,
After installing the latest service release, all of my grids have become grayed-out and icons for them have appeared in the component tray. The ultrawindropdowns have vanished from the form area completely and icons for them have appeared in the component tray. This is the case for all forms in my project.
I get lots of messages saying "Unable to cast object of type 'Infragistics.Win.UltraWinGrid.UltraDropDown' to type 'Infragistics.Win.UltraWinGrid.UltraGrid'"
I have tried the utility for creating the IG toolbox and unregistering/reregistering all IG components, but it didn't help. Can you please suggest how to recover my project.
Thanks,
Richard
Hello Richard,
Please make sure that the 'licenses.licx' file situated in the 'Properties' folder does not contain any information(please delete the contents, not the file itself).
You could also check if the Design.dll's version in the service release installed is the same as in the Global Assembly Cache. The following articles might help you for this: http://help.infragistics.com/Help/NetAdvantage/WinForms/2011.1/CLR2.0/HTML/Win_Using_Global_Assembly_Cache_GAC_Deployment.html
