Hi
Igor is on vacation, so I will answer your question.
If you assign Cols[pos].CellStyle.DropDownControl, all the cells of this column will
use asssigned drop down control.
If you need to have different drop down or other cell settings,
you need to create different CellStyle objects and assign them directly to cells (iGCell.Style property). Also do not
assign column drop down control setting.
iGCellStyle Style1 = new iGCellStyle(); // no drop down
iGCellStyle Style2 = new iGCellStyle(); // with drop down
Style2.DropDownControl = _comboBereiche;
foreach(iGCell cell in iGrid1.Cols[pos].Cells)
if(some_condition) { cell.Style = Style1 } else {cell.Style = Style2}
