private void ShowDBGrid()

{

CONN = new Conn();

SQL = "SELECT * FROM evidence";

try

{

CONN.OpenConn();

MYCMD = new MySqlCommand(SQL);

MYDA = new MySqlDataAdapter(SQL, CONN.MYCONN);

DataSet DS = new DataSet();

MYDA.Fill(DS);

dgvDiagnose.DataSource = DS.Tables[0].DefaultView;

DataGridViewCheckBoxColumn checkBoxColumn = new DataGridViewCheckBoxColumn();

checkBoxColumn.HeaderText = "";

//checkBoxColumn.Width = 10;

checkBoxColumn.Name = "checkBoxColumn";

dgvDiagnose.Columns.Insert(0, checkBoxColumn);

dgvDiagnose.Columns[1].HeaderText = "";

DataGridViewComboBoxColumn comboBoxColumn = new DataGridViewComboBoxColumn();

comboBoxColumn.HeaderText = "";

//comboBoxColumn.Width = 30;

comboBoxColumn.Name = "comboBoxColumn";
