This control renders bool values as checkboxes.

It would get too easy here:

Conisder your checkbox column is the 2nd column in your datagridview.

private void YourDatagridview_CellValueChanged(object sender, DataGridViewCellEventArgs e)
    {
         if (IsHandleCreated)
        {
            if (YourDatagridview.CurrentCell == YourDatagridview.Rows[e.RowIndex].Cells[1])
            {
                if (Convert.ToBoolean(YourDatagridview.CurrentCell.Value) == true)
                {
                    for (int i = 0; i < YourDatagridview.RowCount; i++)
                    {
                        if (YourDatagridview.Rows[i].Cells[1] != YourDatagridview.CurrentCell)
                        {
                            YourDatagridview.Rows[i].Cells[1].Value = false;
                        }
                    }
                }
            }
        }
    }

And call this too:

private void YourDatagridview_CurrentCellDirtyStateChanged(object sender, EventArgs e)
    {
        if (this.YourDatagridview.IsCurrentCellDirty)
        {
            YourDatagridview.CommitEdit(DataGridViewDataErrorContexts.Commit);
        }
    }

and Voila!!
