Displaying image in row header of DataBoundGrid

How do I display an icon in the row header of databoundgrid? I am faking MS DataGrid style ErrorProvider using PrepareViewStyleInfo to display an error icon and tooltip text when I have have error in my data. e.Style.ImageList = this.errorImageList; e.Style.ImageList = this.errorImageList; e.Style.CellTipText = err; works for the content cells but for the row header tooltip appears, but error icon is not set.
