关于DataList分页的问题，拜托帮我看看！！

Question

页面代码：
<asp:DataList ID="DataList1" runat="server" Width="668px" CellSpacing="3" DataSourceID="SqlDataSource1" pagesize="3">
        <ItemTemplate>
            <div class="mainBox" style="width:660px; height:100px; border:solid 2px; border-color:Blue;">
                <div class="leftBox" style="width:20%; height:100px; border-right:solid 2px; border-right-color:Blue; float:left; text-align:center;">
                    <asp:Image ID="Image1" runat="server" Width="78px" Height="80px" Text='<%# Eval("facing","~/images/.jpg") %>' /><br />
                    <asp:Label ID="nameLabel" runat="server" Text='<%# Eval("name") %>'></asp:Label>
                </div>
                <div class="rightBox" style=" height:100px; float:left;">
                标题：
                    <asp:Label ID="titleLabel" runat="server" Text='<%# Eval("title") %>'></asp:Label><br />
                    <asp:Label ID="wdateLabel" runat="server" Text='<%# Eval("wdate") %>'></asp:Label><br />
                    <asp:Label ID="messageLabel" runat="server" Text='<%# Eval("message") %>'></asp:Label><br />
                回复：
                    <asp:Label ID="re_messageLabel" runat="server" Text='<%# Eval("re_message") %>'></asp:Label><br />
                </div>
            </div>
        </ItemTemplate>
        <FooterTemplate>
            <table width="660px">
                <tr>
                    <td style="width:120px;" align="center">
                        <asp:Label ID="lblCurPage" runat="server" Text="Label"></asp:Label>
                    </td>
                    <td style="width:540px;">
                        <asp:HyperLink ID="lnkFirst" runat="server">第一页</asp:HyperLink>
                        <asp:HyperLink ID="lnkPrev" runat="server">上一页</asp:HyperLink>
                        <asp:HyperLink ID="lnkNext" runat="server">下一页</asp:HyperLink>
                        <asp:HyperLink ID="lnkLast" runat="server">最后一页</asp:HyperLink>
                     </td>
                </tr>
            </table>
        </FooterTemplate>
    </asp:DataList>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:MyDataBaseConnectionString %>" SelectCommand="SELECT [name], [title], [message], [wdate], [re_message] FROM [Message] ORDER BY [wdate] DESC"></asp:SqlDataSource> 后台代码：

        }
        if (!objPage.IsLastPage)

            lnkLast.Visible = false;
        }
        DataList1.DataSource = objPage;
        DataList1.DataBind();
        conn.Close();
    }
}
运行以后提示<FooterTemplate></FooterTemplate>部分的lblCurPage,lnkPre,lnkFirst,lnkLast,lnkNext名称在上下文不存在，我明明已经把Label和HyperLink的ID都改成以上名称，怎么会不存在呢！！！帮一下忙呢！！

Answer 1

因为你吧Label和HyperLink都写到Template里了,想要找到他就必须在相应的Template里用 .FindControl(ID)来获取

Answer 2

这个问题可以再DataBound事件中绑定，判断当前Row是否为Footer，如果是的话，可以FindControl（“id”）来找到控件，然后再进行赋值或者其他操作

你吧分页的写出来就可以了

谢谢你喔 这个问题解决了 可是运行的时候又出现这样的错误
ConnectionString 属性尚未初始化。说明: 执行当前 Web 请求期间，出现未处理的异常。请检查堆栈跟踪信息，以了解有关该错误以及代码中导致错误的出处的详细信息。 异常详细信息: System.InvalidOperationException: ConnectionString 属性尚未初始化。源错误: 
行 26:         SqlDataSource sql = new SqlDataSource();
行 27:         sql.SelectCommand = "SELECT [name], [title], [message], [wdate], [facing], [re_message] FROM [Message] ORDER BY [wdate]";
行 28:         DataView dv = (DataView)sql.Select(DataSourceSelectArguments.Empty);
行 29:         PagedDataSource objPage = new PagedDataSource();
行 30:         objPage.DataSource = dv;
请问这是怎么回事呢
