ComboBox

Trying to load a combobox dynamically with the following piece of code.
count gives exact number of rows !!, but the combobox does not show anything..!!.
Any help is greatly appreciated.

Code:

---

public void loadComboBox(OdbcConnection con)
    {
        con = getConnection();
        con.Open();
       
        string str = "select distinct mgrCode from MgrDetail";
           
        OdbcCommand nonqueryCommand = con.CreateCommand();
        nonqueryCommand.CommandText = str;
        nonqueryCommand.CommandType = CommandType.Text;
        OdbcDataReader thisReader = nonqueryCommand.ExecuteReader();

        DataSet ds = new DataSet();
        DataTable dTable = new DataTable("TableA");
        dTable.Load(thisReader);
        ds.Tables.Add(dTable);
        this.ComboBox1.DataSource = ds.Tables[0];
        int count = this.ComboBox1.Items.Count; //count gives exact number of rows !!
       
        con.Close();

    }

You need to set DisplayMember and ValueMember for ComboBox. Like:

Code:

---

ComboBox1.DisplayMember = FieldNameinDataTable;

That worked..
Thanks a lot.
