i have one data gridview with commodities names and their id's..when i select a record i need to display selected name in the combobox....if i click on dropdown , the rest of the names to displayed for updating the value...i am using two tables..one for getting edited record from the database and other for the binding remaining names....data coming to the tables...but second table is only binding....selected value is not displaying at the top..

What I have tried:

if (varietyid != 0 && op_mode == "Edit")
                {
                    btnSave.Text = "Modify";
                    op_mode = "Edit";
                    mode = 6;         
                   
                    cmdVrty = objVariety.getCommodityAndVariety(mode,varietyid,cid);

                    int cnt;
                    cnt = cmdVrty.Rows.Count;
                   

                    for (int i = 0; i < cnt - 1; i++)
                    {
                        DataRow row;
                        row = cmdVrty.NewRow();
                        row["commodity"] = cmdVrty.Rows[0]["NAME"].ToString();
                        row["cid"] = Convert.ToInt32(cmdVrty.Rows[0]["COMMODITYID"]);
                      
                        cmdVrty.Rows.InsertAt(row, 0);
                        cmbCommodity.DataSource = cmdVrty;
                        cmbCommodity.DisplayMember = "commodity";
                        cmbCommodity.ValueMember = "cid";
                      
                      

                    bindcmbforedit();
}

  public void bindcmbforedit()
        {
            mode = 6;

            bindTable = objVariety.getVarietybyCommodity();
            cmbCommodity.DataSource = bindTable ;
            cmbCommodity.DisplayMember = "NAME";
            cmbCommodity.ValueMember = "ID";
       }
