Just wondering if anyone has ever managed to find a way to have a datagridview image button column in a template field which display different images on different rows depending on some data element in the row. Our application needs to display a series of fees charged against an account column which will be either less then 500, 500 to 1000 or >1000. Some of those fees are charged at a full rate, others at a partial rate, and some are not charged at all. The user would like to see a simple 3-state graphic which would convey the simple info: full-charge, partial-charge, or no-charge. Sounds easy enough but I've not yet managed to find a way to do this. Every time I attempt to modify the individual cell's graphic it seems to want to change the graphic for all the rows.
