[C# Win App] สอบถามการใช้ Checkbox ใน DataGridView เพื่อบันทึกข้อมูลลง Database ครับ

            DataGridViewTextBoxColumn column;
            DataGridViewCheckBoxColumn columnchk;

            column = new DataGridViewTextBoxColumn();
            column.DataPropertyName = "menuname";
            column.HeaderText = nMenuname;
            column.Width = 95;
            this.dataGridView1.Columns.Add(column);

            columnchk = new DataGridViewCheckBoxColumn();
            columnchk.DataPropertyName = "viewdata";
            columnchk.HeaderText = nView;
            columnchk.Width = 85;
            this.dataGridView1.Columns.Add(columnchk);

            columnchk = new DataGridViewCheckBoxColumn();
            columnchk.DataPropertyName = "writedata";
            columnchk.HeaderText = nWrite;
            columnchk.Width = 85;
            this.dataGridView1.Columns.Add(columnchk);

            columnchk.Width = 85;
            this.dataGridView1.Columns.Add(columnchk);

            columnchk = new DataGridViewCheckBoxColumn();
