What is the correct way of datagridviewcomboboxcolumn bind with sql database and re- arrange with other column. Suppose if I have columns like below.

1. Srno

2. Particulars // this columns is for datagridviewcomboBoxColumn

3. Amount.

I wants the datagridview’s columns correct order as above and the same is for the purpose

of data entry.

Suppose开发者_JS百科 if I have Following Dummy Table like

dummy

1. Srno

2. Particulars

3. Amount.

MySqlConnection Code is as below.

string cons = "server=.;initial catalog=maa;uid=mah;pwd=mah";
SqlConnection con = new SqlConnection(cons);
con.Open();
string sql = "select particulars from dummy";
SqlDataAdapter dap = new SqlDataAdapter(sql, con);
DataSet ds = new DataSet();
dap.Fill(ds);
DataGridViewComboBoxColumn cmb = new DataGridViewComboBoxColumn();
cmb.DataSource = ds.Tables[0];
cmb.DisplayMember = "name";
cmb.ValueMember = "name";
dataGridView1.Columns.Add(cmb);

The above datagridviewcomboboxcolumn is set to dgv.columns[0] where as I wants the dgv

columns orders as below.

1. Datagridview.columns[0] is for srno
