I used to have a project in which my datagridview have a checkboxcolumn, created dynamically. I implemented this code in CellEditEnding event, to prevent more then one checkbox from being checked..

if (e.ColumnIndex == 0) //column index
            bool hasOtherCheckboxChecked = false;
            foreach (DataGridViewRow dgvr in dataGridView1.Rows)
                DataGridViewCheckBoxCell cell = (DataGridViewCheckBoxCell)dgvr.Cells[e.ColumnIndex];
                if (cell.Value == cell.TrueValue && dgvr.Index != e.RowIndex)
                    hasOtherCheckboxChecked = true;
            DataGridViewCheckBoxCell currentCell = (DataGridViewCheckBoxCell)dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];
            if (currentCell.Value == currentCell.TrueValue && hasOtherCheckboxChecked)
                currentCell.Value = currentCell.FalseValue;

Now, i migrated my aplication too a wpf format, and i cant use this anymore.
Can anyone help me. maybe in converting the code, or sugesting another alternative that doesnt required setting autogeneratecolumn to false.

Please help!
Thanks in advance.
