Hi Andreas,
You could find additional information in our "Breaking changes in
RadGridView" document that
GridCellElement.Value is removed. You could use
GridDataCellElement.Value instead.
If you still experience a design-time exception in your form, you could try to perform a clean install of the RadControls suite:
- Uninstall all versions of Telerik controls
- Clean your GAC, and your ...\Program files\Telerik directory from all Telerik assemblies
- Install latest version Q1 2008 Service Pack 1
- Clean and rebuild your solution
- Restart Visual Studio
Please let me know if this does not solve your issue.
If you have other questions, do not hesitate to contact me again.
Best wishes,
Martin Vasilev
the Telerik team
