我做的翻页为什么在ie7或ie8上点下一页，再点上一页就无效了。高手指点

Answer 1

http://dys198102.w43.cndns.com/news.html大家可以用360或ie7,ie8试一下，点下一页后，再点上一页就没用了

Answer 2

我来鄙视一下IE7、IE8，尤其是IE8

Answer 3

搞Web开发的最怕碰上一些不成熟的，或者说是变态的浏览器，样式上把人搞的烦死了

Answer 4

是的，老是出现一些莫名其妙的bug，还找不到原因

Answer 5

在网上看到一点资料。
<script language="javascript">...
             <!--
             function __doPostBack(eventTarget, eventArgument)
             ...{
                var theForm = document.Form1;       //指runat=server的form
                theForm.__EVENTTARGET.value = eventTarget;
                theFrom.__EVENTARGUMENT.value = eventArgument;
                theForm.submit();
             }
             -->
             </script>
             <input id="Button1" type="button" name="Button1" value="按钮" onclick="javascript:__doPostBack('Button1','')">        
ASPX页面有包含asp:LinkButton或者带有AutoPostBack属性且其值为true的服务器控件时，ASP.NET会自动为页面生成下面的脚本：
<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" /> 
<input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" /> 
这两个参数分别由隐藏的两个表单域__ EVENTTARGET和__ EVENTARGUMENT保存。
这两个隐藏的表单可以查找引起页面回送的控件ID和回送时的参数：
string target = Request.Params["__EVENTTARGET"];
string args = Request.Params["__EVENTARGUMENT"];
asp:Button和asp:ImageButton不是使用__doPostBack回送页面，所以使用这两个控件回送页面时，上面的代码是无效的。 
这个会不会和LinkButton有关系。高手指点了，急

我下载了个AspNetPager.dll,但是点一下，就是没反应，有时候下边数字显示已翻页，但数据还是原来样子。
前台：
                <asp:DataList ID="DataList1" runat="server" width="100%">
                <ItemTemplate>
                    <table width="100%" border="0" cellspacing="0" cellpadding="0">
                      <tr>
                        <td width="2%" height="30"><div align="center"><img src="images/png1.png" width="6" height="14"></div></td>
                        <td width="15%" class="neirong">【<%# Eval("Pro_Sclass") %>】</td>
                        <td width="69%"><a href="newsshow_<%# Eval("id") %>.html#TID=1" target="_blank" class="neirongl"><%# FormatStr(Eval("pro_id").ToString().Trim(), 46)%></a></td>
                        <td width="14%" class="neirong"><%# DateTime.Parse(Eval("pro_time").ToString()).ToString("yyyy-MM-dd")%></td>
                      </tr>
                    </table>
