Question

我正在尝试访问嵌套在DataList ItemTemplate中的控件。对于我的生活，我无法理解我做错了什么。一个例子：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

    <!DOCTYPE html>

    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
        <title></title>
    </head>
    <body>
        <form id="form1" runat="server">
            <div>
            </div>
            <asp:DataList ID="DataList1" runat="server">
                <ItemTemplate>
                    <asp:Label ID="lblSavings" runat="server" Text="Label"></asp:Label>
                </ItemTemplate>
            </asp:DataList>
        </form>
    </body>
    </html>

在后面的代码中我试图访问“lblSavings”标签控件：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        lblSavings.Text = "String";
    }
}

这就像后面的代码看不到那种控制或什么的。我在某个地方错过了一步，还是我只是疯了？

全部谢谢！

Hope this will help you.
Feel free to ask if got any query.

protected void Page_Load(object sender, EventArgs e)
{
          Label lbl   = Datalist1.Item.FindControl("lblSavings") as Label;
} 

or at time of item bound

protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs 
e) 
{
Label Label1 = e.Item.FindControl("lblSavings") as Label;
}
