將數據網格綁定到數據集

Question

我試圖將數據集作爲網格來源。所以，這是我所做的：

 SqlCommand cmd = new SqlCommand("TEST", 
               conn); 
     cmd.CommandType = CommandType.StoredProcedure; 
     SqlDataAdapter da = new SqlDataAdapter(cmd); 
     DataSet d = new DataSet(); 
     da.Fill(d); 
     grid2.DataSource = d; 
     grid2.DataBind(); 

但是，我無法得到結果。網格在頁面上不可見。可以讓我知道如何做到這一點？

Answer 1

您的代碼不完整;然而，這是如何做的：

//notice how the connection is enclosed in a using block 
using (SqlConnection conn = new SqlConnection("ConnectionString")) 
{ 
     conn.Open();//don't forget to open the connection 
     SqlCommand cmd = new SqlCommand("TEST",conn); 
     cmd.CommandType = CommandType.StoredProcedure; 
     SqlDataAdapter da = new SqlDataAdapter(cmd); 
     DataSet d = new DataSet(); 
     da.Fill(d); 
     grid2.DataSource = d; 
     grid2.DataBind(); 
} 

順便說一句，你不需要DataAdapter。你可以簡單地做到這一點：

//notice how the connection is enclosed in a using block 
using (SqlConnection conn = new SqlConnection("ConnectionString")) 
{ 
     conn.Open();//don't forget to open the connection 
     SqlCommand cmd = new SqlCommand("TEST",conn); 
     cmd.CommandType = CommandType.StoredProcedure; 

     DataTable d = new DataTable(); 
     d.Load(cmd.ExecuteReader()); 
     grid2.DataSource = d; 
     grid2.DataBind(); 
}
