please use dbnull instead.  The database field that it is boundto is an int.  If I change the display member to be the same as the valuemember (both to be int),

It uses a stored procedure to return a set of data. I am using a Telerik.Reporting.Chart bound to a Telerik,Reporting.DataSource. I am currently temporarily working around this by changing the sproc to using COALESCE to replace the NULLs with 0s.

I would suggest either: 1. Once we review it, we would be able to provide more information. Try doing this: if (!string.IsNullOrWhiteSpace(data[i])) row[i] = data[i]; else row[i] = DBNull.Value; This bypasses the conversion requirements for both sides to be the same. Check This Out Frankly, you shouldn't even have to transfer data from the grid to the DataTable anyway because they should be bound in the first place.
