a brilliant question!. The following code should be of help. public class RatingEditor : UITypeEditorEx { public overridebool GetPaintCellSupported() { //The cellshould be repainted in the editor return true; } public overridevoid PaintCell(PaintCellEventArgs e) { //Do basicpainting without text e.Text =string.Empty; e.PaintAll(); e.Handled =true; //Draw thestars over the cell Rectanglebounds = e.Cell.VirtualBounds; bounds.Width =Resources.star_grey.Width; for (int i = 0;i { //Selectimage if (e.Cell.Value!= null && e.Cell.Value is int) { intcurRating = (int) e.Cell.Value; Imageimage = i >= curRating ? Resources.star_grey : Resources.star_yellow; e.Graphics.DrawImage(image bounds); bounds.X += bounds.Width; } } } public overrideStopEditReason EditCell(IGridEditorService service Cell cell StartEditReasonreason) { //Edit the cellif the user has clicked on the cell with the left button if (cell.Row !=null && Equals(StartEditReason.LButtonClick reason)) { Point pt =cell.Row.Grid.PointToClient(Cursor.Position); Rectanglebounds = cell.VirtualBounds; intimageWidth = Resources.star_grey.Width; if(bounds.Contains(pt) && imageWidth > 0) { //Set anew rating to the data object cell.Value = ((pt.X - bounds.X)/imageWidth) + 1; cell.Invalidate(); } } returnStopEditReason.UserStop; } }
