Create a datatable with two columns use a first column as autoincrement as true and AutoIncrementStep=1 like

DataTable _test = new DataTable();
DataColumn c = new DataColumn("sno", typeof(int));
c.AutoIncrement = true;
c.AutoIncrementSeed = 1;
c.AutoIncrementStep = 1;
_test.Columns.Add(c);
_test.Columns.Add("description");
gvlisting.DataSource = _test;
