我想实现数字分页，但一直只显示 “1”，用按钮“上一页”，“下一页”的话，也不管用，不能点击 <form id="form1" runat="server">
    <div>
        <asp:DataPager ID="DataPager1" runat="server" PagedControlID="lvPaging" PageSize="5">
            <Fields>
                <asp:NextPreviousPagerField ButtonType="Button" ShowFirstPageButton="True" ShowLastPageButton="True"  />
            </Fields>
        </asp:DataPager><br />
        <asp:ListView ID="lvPaging" runat="server" OnItemCreated="lvPaging_ItemCreated" >
        
            <ItemTemplate>
                <asp:Label ID="lbXUHao" runat="server"  ForeColor="Blue"></asp:Label>
                 <%#Eval("id") %>&nbsp;&nbsp;
               <%#Eval("Title") %>&nbsp;&nbsp;
               <%#Eval("Content") %>
            </ItemTemplate>
            <ItemSeparatorTemplate>
                ----------------------------------------<br />
            </ItemSeparatorTemplate>
        </asp:ListView><br />
        <asp:DataPager ID="DPNumber" runat="server" PagedControlID="lvPaging" PageSize="5" OnPreRender="DPNumber_PreRender">
            <Fields>
                <asp:NextPreviousPagerField FirstPageText="&lt;&lt;" LastPageText="" NextPageText="" PreviousPageText="" ShowFirstPageButton="True" ShowNextPageButton="False" ShowPreviousPageButton="False" />
                <asp:NumericPagerField />
                <asp:NextPreviousPagerField FirstPageText="" LastPageText="&gt;&gt;" NextPageText="" PreviousPageText="" ShowLastPageButton="True" ShowNextPageButton="False" ShowPreviousPageButton="False" />
            </Fields>
        </asp:DataPager>
    </div>
    </form>
