关于NetAdvantage中连接数据库的操作总结

1.1  动态将一个新建表绑定到UltraWebGrid
                        data=new DataSet("SampleData");
   data.Tables.Add("Materials");
   data.Tables[0].Columns.Add("Product Name");
   data.Tables[0].Columns.Add("Weight (lbs)");
   data.Tables[0].Columns.Add("Price ($)");
   data.Tables[0].Columns.Add("Truck #");
   data.Tables[0].Rows.Add(new object[] {"Sand",500,50.00,"Truck 505"});
   data.Tables[0].Rows.Add(new object[] {"Cement",250,50.00,"Truck 505"});
   data.Tables[0].Rows.Add(new object[] {"Brick",1000,500.00,"Truck 590"});
   data.Tables[0].Rows.Add(new object[] {"6\" Block",800,200.00,"Truck 590"});
   data.Tables[0].Rows.Add(new object[] {"Clean Fill",750,20.00,"Truck 533"});
   data.Tables[0].Rows.Add(new object[] {"Top Soil",2000,200.00,"Truck 501"});
   UltraWebGrid1.DataSource=data.Tables[0].DefaultView;
   UltraWebGrid1.DataBind();
1.2  动态将一个新建表绑定到UltraWebGrid
                       System.Data.DataTable table = new System.Data.DataTable();
       
              System.Data.DataColumn Col1 = new System.Data.DataColumn("PhoneNumbers", Type.GetType("System.Double"));
  System.Data.DataColumn Col2 = new System.Data.DataColumn("Numbers", Type.GetType("System.Double"));
  System.Data.DataColumn Col3 = new System.Data.DataColumn("Dates", Type.GetType("System.DateTime"));
  System.Data.DataColumn Col4 = new System.Data.DataColumn("Currency", Type.GetType("System.Double"));
  dateFormatUS.ShortDatePattern = "MM/dd/yyyy";
 
        table.Columns.Add(Col1);
        table.Columns.Add(Col2);
        table.Columns.Add(Col3);
        table.Columns.Add(Col4);

        DataRow aRow = table.NewRow();
 
        aRow[0] = 6094482000;
 aRow[1] = 111111111;
        aRow[2] = DateTime.Parse("2 / 22 / 02", dateFormatUS);
        aRow[3] = 12;
        table.Rows.Add(aRow);

        aRow = table.NewRow();
        aRow[0] = 6094482017;
        aRow[1] = 123456789;
        aRow[2] = DateTime.Parse("3 / 8 / 02", dateFormatUS);
        aRow[3] = 5678.22;
        table.Rows.Add(aRow);

        aRow = table.NewRow();
        aRow[0] = 8002318588;
        aRow[1] = 987654321;
        aRow[2] = DateTime.Parse("10 / 19 / 71", dateFormatUS);
        aRow[3] = 100000.99;
        table.Rows.Add(aRow);
        //bind to grid
        UltraWebGrid1.DataSource = table;
        UltraWebGrid1.DataBind();
2  通过一般的方法将一个数据库中的表绑定到UltraWebGrid
                string connectionString = "Server=.; Database=Northwind; Integrated Security=True;";
                string sqlConnection = "select * from Customers";
               
                SqlConnection connection = new SqlConnection(connectionString);
                SqlDataAdapter cmdCustomer = new SqlDataAdapter(sqlConnection,connection);
       
                DataSet ds = new DataSet();
                cmdCustomer.Fill(ds,"Customers");
 
                UltraWebGrid1.DataSource = ds;
                UltraWebGrid1.DataBind();

3 通过DAAB将一个数据库中的表绑定到UltraWebGrid
    string connectionString = "Server=.; Database=StarFGS; Integrated Security = True;";
  string sqlConnection = "select * from spflml";

  SqlConnection connection = new SqlConnection(connectionString);
  connection.Open();

  DataSet ds = SqlHelper.ExecuteDataset(connection,CommandType.Text,sqlConnection);
 
  UltraWebGrid2.DataSource=ds;
  UltraWebGrid2.DataBind();
   
  connection.Close();
