AspNetPager控件有一个属性叫CustomInfoHTML，可以把它写在前台页面，如下：
<webdiyer:AspNetPager ID="AspNetPager1" runat="server" PageSize="10" HorizontalAlign="right" Width="100%" Style="font-size: 14px" AlwaysShow="true" FirstPageText="首页" LastPageText="尾页" NextPageText="下一页" PrevPageText="上一页" SubmitButtonText="Go" SubmitButtonClass="submitBtn" CustomInfoStyle="font-size:14px;text-align:left;" InputBoxStyle="width:25px; border:1px solid #999999; text-align:center; " TextBeforeInputBox="转到第" TextAfterInputBox="页 " PageIndexBoxType="TextBox" ShowPageIndexBox="Always" TextAfterPageIndexBox="页" TextBeforePageIndexBox="转到" Font-Size="14px" ShowCustomInfoSection="Left" CustomInfoSectionWidth="19%" PagingButtonSpacing="3px" CustomInfoHTML = "<div style=‘white-space: nowrap‘>共<font color=‘#ff0000‘>%PageCount%</font>页，第<font color=‘#ff0000‘>%CurrentPageIndex%</font>页，共<font color=‘#ff0000‘>%RecordCount%</font>宗</div>" onpagechanged="AspNetPager1_PageChanged"> </webdiyer:AspNetPager>
如果你还想添加一起其他的东西，那么可以在后台单独设置设这个属性，如下：
AspNetPager1.CustomInfoHTML = "<div style=‘white-space: nowrap‘>共<font color=‘#ff0000‘>%PageCount%</font>页，第<font color=‘#ff0000‘>%CurrentPageIndex%</font>页，共<font color=‘#ff0000‘>%RecordCount%</font>宗，" + "总面积为<font color=‘#ff0000‘>" + GetTotalArea() + "</font>平方米</div>";
此处我调用了GetTotalArea()方法。
