100分马上结！分页的问题，如何增加一个输入页码，点击GO进入指定页数？

              <PagerTemplate>
                             <asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page" Enabled=" <%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">首页</asp:LinkButton>
                           <asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev" CommandName="Page" Enabled=" <%# ((GridView)Container.NamingContainer).PageIndex != 0 %>">上一页</asp:LinkButton>
                           <asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page" Enabled=" <%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">下一页</asp:LinkButton>
                           <asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page" Enabled=" <%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>">尾页</asp:LinkButton>
                           (第 <asp:Label ID="LabelCurrentPage" runat="server" Text=" <%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"> </asp:Label> 页，共 <asp:Label ID="LabelPageCount" runat="server" Text=" <%# ((GridView)Container.NamingContainer).PageCount %>"> </asp:Label> 页 <asp:Label ID="LabelTotalCount" runat="server" Text=' <%# (((GridView)Container.NamingContainer).DataSource is System.Collections.ICollection) ? string.Format("，{0} 条记录", ((System.Collections.ICollection)((GridView)Container.NamingContainer).DataSource).Count) : "" %>'> </asp:Label>)
              </PagerTemplate>

增加一个TextBox和一个Button，TextBox里面输入数字，然后点击Button，可以直接在上面的代加里加吗？应该怎么加？谢谢各位了 --------------------编程问答-------------------- 是实现分页么？比较建议使用AspNetPager来实现吧。都写好了！ --------------------编程问答-------------------- 自己写的吗

响应button事件，在后台写代码就可以了啊

--------------------编程问答-------------------- 我感觉主要就是SQL语句，比如说：每页5条，查询第5页数据

select top 5 * from users

where id not IN (select top (5*(5-1)) * from users)

（大概意思在那，语句可能有错

）

就是查询5条数据，不在前20条的5条数据 5*（5-1）；

当文本框输入几的时候X-1的“X”传进去计算第几页的数字，查出结果进行显示，不就OK？ --------------------编程问答-------------------- 技术不到家！我只会用分页控件弄
