C# datagrid specific cell editable

Question

I want to enable a specific cell for editing.

My datagridview is readonly false.

and on cell click i get my columnindex and try to do :

     if (e.ColumnIndex == 7)
                {
                if (String.IsNullOrEmpty(Convert.ToString(dgv.Rows[e.RowIndex].Cells["id"].Value)))
                    {
                        dgv.Columns[e.ColumnIndex].ReadOnly = true;
                    }
                    else
                    {
                        dgv.Columns[e.ColumnIndex].ReadOnly = false;
                        dgv.BeginEdit(true);
                        dgv.Rows[rowindex].Cells[columnindex].Selected = true;
                    }


                }

I solved my problem with this code :

private void dgvLocataire_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e)
       {
           dgvLocataire.BeginEdit(false);

           var ec = dgvLocataire.EditingControl as DataGridViewComboBoxEditingControl;
           if (ec != null && ec.Width - e.X < SystemInformation.VerticalScrollBarWidth)
               ec.DroppedDown = true;

           if ((e.ColumnIndex != 5) && (e.ColumnIndex != 6) && (e.ColumnIndex != 7))
           {
               dgvLocataire.Columns[e.ColumnIndex].ReadOnly = true;
           }

       }

Thanks for your help
