Have found the problem (not me personaly),
There appears to be a compatability issue with VS 2005 and Crystal Reports. We created all our reports in Crystal REports XI but the latest version shipped with VS 2005 is version 10.
Solution is to close VS and uninstall Crystal reports and install it again. It appears to work...
I am having the same problem with CR in VS 2005. It appears that all of the css class names have been removed. This makes it just about impossible to customize the parameter's prompts that are automatically generated.
Can you help?
