manually means what you are taking it from textbox or array, datatable. Can you past your code? It will be easy to understand your requirement.

Go through this logic. If you are adding data then this will help.

DataTable table = new DataTable();
     table.Columns.Add("From", typeof(int));
     table.Columns.Add("To", typeof(int));
     for (int i = 1; i < 10; i++)
     {
         table.Rows.Add(i, i + 1);
         i++;
     }

     GridView1.DataSource = table;

If you are getting data from database then please elaborate some more.
