Create a static datatable and use it for your gridview. static void Main() { // Get the DataTable. DataTable table = GetTable(); // ... Use the DataTable here with SQL. } /// /// This example method generates a DataTable. /// static DataTable GetTable() { // Here we create a DataTable with four columns. DataTable table = new DataTable(); table.Columns.Add(Dosage typeof(int)); table.Columns.Add(Drug typeof(string)); table.Columns.Add(Patient typeof(string)); table.Columns.Add(Date typeof(DateTime)); // Here we add five DataRows. table.Rows.Add(25 Indocin David DateTime.Now); table.Rows.Add(50 Enebrel Sam DateTime.Now); table.Rows.Add(10 Hydralazine Christoff DateTime.Now); table.Rows.Add(21 Combivent Janet DateTime.Now); table.Rows.Add(100 Dilantin Melanie DateTime.Now); return table; }
