如何在代碼隱藏中創建SqlDataSource時將SqlDataSource引用到GridView控件？

Question

在aspx頁面我有：

<asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource1"> 
</asp:GridView> 

在代碼隱藏頁：

protected void Page_Load(object sender, EventArgs e) 
{ 
    SqlDataSource1.ConnectionString = System.Configuration.ConfigurationManager 
    .AppSettings["MyConnectionString"]; 
    SqlDataSource1.SelectCommand = "SELECT * FROM my_table_name"; 
    this.Controls.Add(SqlDataSource1); 
} 

會拋出服務器錯誤：

The DataSourceID of ' GridView1 ' must be the ID of a control of type IDataSource. A control with ID ' SqlDataSource1 ' could not be found.

Answer 1

刪除數據源ID從ASPX

<asp:GridView ID="GridView1" runat="server"> 
</asp:GridView> 

做到這一點從代碼

protected void Page_Load(object sender, EventArgs e) 
{ 
    SqlDataSource1.ConnectionString = System.Configuration.ConfigurationManager 
    .AppSettings["MyConnectionString"]; 
    SqlDataSource1.ID = "SqlDataSource1"; 
    this.Page.Controls.Add(SqlDataSource1); 
    SqlDataSource1.SelectCommand = "SELECT * FROM my_table_name"; 
    GridView1.DataSource = SqlDataSource1; 
    GridView1.DataBind(); 
} 

Answer 2

我想命名的SqlDataSource等於設置其ID，它不是。我必須明確設置SqlDataSource.ID = "SqlDataSource";
