I have datagridview which is populated with 8 columns also it is databound.Now my requirement is I need last column say ABC As comboboxcolumn.But if in database,this ABC column has some value for a particular row,then that value should be displayed in that row's cell as selected value.Please help me to solve this.Its urgent.

Could you please give your code?

Dim cmbcaste As New DataGridViewComboBoxColumn()
        cmbcaste.Name = "Caste"
        cmbcaste.HeaderText = "Caste"
        sql = "Select Description from Category where Catgry = 1"
        If rs.State = 1 Then rs.Close()
        rs.Open(sql, MainCon, 1, 3)
        Do While Not rs.EOF

I have written above code but this is adding new column and also only filling combobox.

I am using combobox in datagridview.the combobox have both selected text and selected value.After selecting some rows i need to loop through the gridview and get selected text and selected value of each row.When I use dgSales["item",row].value i am getting only the selected value.I need the selected text also. Please give me a solution ..

private void button4_Click(object sender, EventArgs e)
      List<string> dgwList = new List<string>();
      int numberRows = dataGridView1.Rows.Count;
      int row = -1;
      int column = -1;
        for (int i = 0; i < numberRows; i++)
          column = -1;
          int numberColumns = dataGridView1.Columns.Count;
          for (int j = 0; j < numberColumns; i++)
            if (dataGridView1[row, column].Selected == true)
              string strCellValue = dataGridView1[row, column].Value.ToString();
