this.gridControl1.ExcelLikeCurrentCell = true;
this.gridControl1.ExcelLikeSelectionFrame = true;
But you may or may not like the look of this as it draws a fatter selection frame that the default.
If you do not want to use the excel properties, then I think you can handle a couple of events, and manually add/remove the currentcell from teh grid.Selections collection.
private void gridControl1_CurrentCellMoving(object sender, GridCurrentCellMovingEventArgs e) { GridCurrentCell cc = this.gridControl1.CurrentCell; this.gridControl1.Selections.Remove(cc.RangeInfo); this.gridControl1.Selections.Add(GridRangeInfo.Cell(cc.MoveToRowIndex, cc.MoveToColIndex)); } private void gridControl1_CellClick(object sender, GridCellClickEventArgs e) { this.gridControl1.Selections.Add(GridRangeInfo.Cell(e.RowIndex, e.ColIndex)); }
