Hi, Why you are using two dataset, use one data set and get values with the join of your tables in query. if you have any relation with those tables.

Check this

C#

DataTable dt1 = new DataTable();
           dt1.Columns.Add("Name");
           dt1.Columns.Add("city");
           dt1.Rows.Add("Raja", "Newyork");
           dt1.Rows.Add("Guna", "claifornia");


           DataTable dt2 = new DataTable();
           dt2.Columns.Add("DoorNo");
           dt2.Rows.Add(25);
           dt2.Rows.Add(36);


           DataTable dt3 = new DataTable();
           dt3.Columns.Add("Name");
           dt3.Columns.Add("city");
           dt3.Columns.Add("DoorNo");

           if (dt1.Rows.Count == dt2.Rows.Count)
               for (int i = 0; i < dt1.Rows.Count; i++)
                   dt3.Rows.Add(dt1.Rows[i]["Name"], dt1.Rows[i]["city"], dt2.Rows[i]["DoorNo"]);
