datalist中获取值的方法

Question

aspx文件：
<asp:DataList ID="dlTopSpeak" runat="server" OnItemCommand="dlTopSpeak_ItemCommand">
    <ItemTemplate>
        <table border="0" cellpadding="0" cellspacing="0" width="190px">
            <tr>
                <td>
                    <asp:LinkButton ID="lbtntitle" runat="server" CommandName="title" CommandArgument='<%#Eval("SSpeakID") %>'><%#Eval("speaktitle") %></asp:LinkButton>
                    <asp:Label ID="labUserID" runat="server" Visible="false"><%#Eval("SUserID") %></asp:Label>
                </td>
                <td>
                    <asp:LinkButton ID="lbtnUsername" runat="server" CommandName="name" CommandArgument='<%#Eval("SUserID") %>'><%#Eval("username") %></asp:LinkButton>
                </td>
            </tr>
        </table>
    </ItemTemplate>
</asp:DataList>cs文件：
    protected void dlTopSpeak_ItemCommand(object source, DataListCommandEventArgs e)
    {
        if (e.CommandName == "title")
        {
            //string ID = ((Label)e.Item.FindControl("labUserID")).Text;
            Response.Redirect("speak.aspx?speakID=" + e.CommandArgument.ToString() + "&userID=" + ID);
        }
        else if (e.CommandName == "name")
        {
            Response.Redirect("BlogList.aspx?ID=" + e.CommandArgument.ToString());
        }
    }我想在点击lbtntitle的时候链接"&userID=" + ID中的ID值是从labUserID得到的，或者是从lbtnUsername的e.CommandArgument.ToString()中得到，请问有什么方法能够实现？谢谢！

Answer 1

DataKeyField设置为你需要的字段
然后取值:
DataList1.DataKeys[e.Item.ItemIndex].ToString();

Answer 2

if (e.CommandName == "title")
        {
            Label labUserId = e.Item.FindControl("labUserID") as Label;
            if(labUserId!=null)
           {
              string ID=labUserId.Text;
            Response.Redirect("speak.aspx?speakID=" + e.CommandArgument.ToString() + "&userID=" + ID);
            }
}
