The code below works for clicking on a cell and showing the text in the proper textbox. I am monitoring cell 0 and 2-5.

I am currently working with a datatable and I want to be able to show richtext in a column of the table. First question can this be done? I can force the column to be Type Of richtext box. However, when I try to view/display the table, I get something like..."System.Windows.Forms.RichTextbox, Text: Text That I have added" in the column.
Is there a way that I can get it to show the rich text in a cell of a datacolumn of a datatable?

View 6 RepliesThe problem is that if you never enter anything into a cell for a new row then that cell is never validated. This is a problem because I have columns that should not be null. I am doing the check in the row level validation and storing the information about which cells are empty that should not be empty. The row level validation works fine and the row level validation error indicator goes on,(red exclamation mark at the beginning of the row) but I also need a visual indicator on the individual cells that are in error.
I am thinking that setting the HasError property for the cells that are in error should cause them to display n error style (the default red border). Is there a way to this this either from XAML (perferably) or from code?Alternatively I could cause those cells to re-validate when the row editing is finished. Does anyone know how to do this?
I'm using something call ultragrid in my program.The program works as a mini-record keeping area (Like any datagrid, really).

This, thus far, works perfectly What I want to do is this: I want to select a record (A cell) in the column 'Dog and have the text of that cell appear in a textbox. This is what I've tried with no success.
