If you need to populate all the data..then do the following

C#

 DataTable dtb = new DataTable();
foreach (DataRow row in ds1.Rows)
 {
DataSet ds = new DataSet();
 string CountryId = row["Member_Name"].ToString();
 //string CountryId = ds1.Rows[0][column].ToString();
 SqlCommand cmd = new SqlCommand("select Member_Name,Id,Gender,Member_DOB,[Placement_Side],[City],[Join_Date],IntroducerID,SponsorID,Introducer_Name from Member_registration where Introducer_Name='" + CountryId + "' ", con);
 SqlDataAdapter da = new SqlDataAdapter(cmd);
 //LData.MyDataContext db = new LData.MyDataContext();
 // var result = new DataTable();
 // var row = result.NewRow();

 da.Fill(ds);
 
 foreach (DataRow dr in ds.Rows)
 {
   dtb.ImportRows(dr);

 }
  
 con.Close();
 }
 gv.DataSource = dtb;
 gv.DataBind();
