如何，使用datalist控件，显示数据源里的数据，有示例最佳！

以下是快速入门中的示例程序：
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SqlClient" %><html><script language="C#" runat="server">    SqlConnection myConnection;    void Page_Load(Object sender, EventArgs e) {        myConnection = new SqlConnection("server=(local)\\NetSDK;database=pubs;Integrated Security=SSPI");        if (!Page.IsPostBack) {
            SqlDataAdapter myCommand = new SqlDataAdapter("select * from Titles where type = 'business'", myConnection);            DataSet ds = new DataSet();
            myCommand.Fill(ds, "Titles");            MyDataList.DataSource=ds.Tables["Titles"].DefaultView;
            MyDataList.DataBind();
        }    }    void MyDataList_Select(Object sender, EventArgs e) {        String title = MyDataList.DataKeys[MyDataList.SelectedItem.ItemIndex].ToString();
        SqlDataAdapter myCommand = new SqlDataAdapter("select * from Titles where title_id = '" + title + "'" , myConnection);        DataSet ds = new DataSet();

  1.   

    我将你的代码帖到一个空白地web窗体里,但是还是显示不出datalist啊
    不是我贴地不对啊,以前对asp不怎么了解
    比较弱地问题啊!
    望指点..
    hehe
      

  2.   

    html文件中
    <asp:datalist id="DtLFeedback" runat="server" Width="100%" BorderColor="#999999" BorderStyle="None"
    BackColor="White" CellPadding="3" GridLines="Vertical" BorderWidth="1px" RepeatColumns="1">
    <SelectedItemStyle Font-Bold="True" ForeColor="White" BackColor="#008A8C"></SelectedItemStyle>
    <AlternatingItemStyle BackColor="Gainsboro"></AlternatingItemStyle>
    <ItemStyle ForeColor="Black" CssClass="Grid" BackColor="#EEEEEE"></ItemStyle>
    <ItemTemplate>
    <b>
    <%# DataBinder.Eval(Container, "DataItem.yhmc") %>
    :</b>
    <%# DataBinder.Eval(Container, "DataItem.FeedbackContent") %>
    <%# DataBinder.Eval(Container, "DataItem.FeedBackTime") %>
    </ItemTemplate>
    </asp:datalist>
    cs文件中 DtLFeedback.DataSource = mydv;
    DtLFeedback.DataBind();
