Please help me my whole graduate project has stopped becuase of this error..
One would think you'd have done some research before you started. All .NET controls that show text, show plain text, only a rich text control will show text using formatting like bold, italics, etc. Even then, I'm not sure how you're getting data from Excel ( which is NOT a database, BTW ), if the text is compatible with RTF or not. I'd think that if it was, the extra formatting information you're recieving would be screwing up your data grid in ways that you would have mentioned, if it were so.
your first step is to get the data including the formatting information. Your second is to make sure that data is compatible with the rich text control. Your third is to use rich text controls to show your data. There are alternatives, but none of them are pretty IMO.
