You need to derive a custom column style, override its Paint method and draw the image. In the attached samples, (VB and C#), there are two custom column styles. One style is a stand-alone unbound column that just displays an image. The second custom column style adds the image to the left side of a bound column. In both cases, the actual image that is displayed is from an imagelist passed into the column in its constructor. The index of the image to be drawn on a particular row is determined by a delegate passed into the column style through its constructor.
