Not totally sure what you're trying, but...

I think the issue is that you are binding to an Integer column, and so you can't change the value to " ". What you can do is in your SELECT statement, have the statement do the conversion for you, then check for IsBlank() instead of 0 when doing the color.

Would that work in your case?

>In the ItemCreated event I am changing the color of the cell based off the value, it will either return a zero (empty) or a number greater than zero (caseID). If it is zero, I change the cell backcolor to green otherwise I change it to red and populate the tooltip with what procedure is being done. On the ones where the value is zero, it displays the zero, I want to change that to be blank. It is just a standard datagrid with no properties set in the designer. Below is the code I have (don't change the text, but doesn't throw an error either).
