I am running IE10 on Windows 8. If I run in Compatibility Mode, I do not get errors. Is IG compatible with IE10? It has something to do with the AJAX and your webdatagrid or other controls that require AJAX. Firefox works fine. My concern here is I can't tell the world to turn on compatibility mode. You may need to escalate this.

One last piece to my error above is that it only happens when running the app view VS2010 but not when I am running outside of VS2010.

here is more on the error I get:

VersionUtility Tools

I am really having this issue big time with WebDataGrid. I get this error whenever I display the grid. Seems like it is AJAX related. I also get the error when I run the Version Utility to upgrade the solution to 12.1. You recommend in 2. above to Update to AJAX controls. How or where is this done?
