Hello You can use TColumnEh.OnGetCallParams event to set CheckboxState before cell is drawn like this: Code: procedure TForm1.DBGridEh1Columns7GetCellParams(Sender: TObject;
EditMode: Boolean; Params: TColCellParamsEh); begin if (Params.CheckboxState = TCheckBoxState.cbGrayed) then Params.CheckboxState := TCheckBoxState.cbUnchecked; end; |
