Hi Alves,

Thank you for your interest in Syncfusion product.

If you want to click the check only one time, then please try using Record.Id and conditional statements in TableControlCheckBoxClick event to achieve this

behavior. The Record is maintain the unique Id in GridGroupingControl. The TableControlCheckBoxClick event is fired, when the check box has been clicked in

GridGroupingControl. The Cancel property is used in TableControlCheckBoxClick event to cancel the check box click after the first click.

Refer the code below:

List lis = new List();
void gridGroupingControl1_TableControlCheckBoxClick(object sender, GridTableControlCellClickEventArgs e)
{
e.TableControl.CurrentCell.MoveTo(e.Inner.RowIndex, e.Inner.ColIndex);
GridTableCellStyleInfo sty = e.TableControl.GetTableViewStyleInfo(e.Inner.RowIndex, e.Inner.ColIndex);
if (sty.TableCellIdentity.DisplayElement.Kind == DisplayElementKind.Record)
{
if (lis.Contains(sty.TableCellIdentity.DisplayElement.GetRecord().Id))
{
e.Inner.Cancel = true;
}
else
{
lis.Add(sty.TableCellIdentity.DisplayElement.GetRecord().Id);
this.gridGroupingControl1.Refresh();
}
}
}

Refer the sample in below link:
