Here is one way you can do this.

It changes the row header cell style to "Header" to avoid seeing the default pencil and triangle, and then uses PrepareViewStyleInfo to show an icon using style.ImageList to provide a BackgroundImage for the header cells. The sample gets the image index from a column in the datatable being displayed.
Another way you can do this is to handle the CellDrawn event and draw the bitmap over the cell at that point when e.ColIndex == 0 and e.RowIndex > 0.
