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？

Question

              <PagerTemplate> 
                           &nbsp;&nbsp;<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

Answer 1

是实现分页么？比较建议使用AspNetPager来实现吧。都写好了！

Answer 8

我都是用URL分布，传一个参数给URL就行了。

Answer 9

这个简单...
响应button事件，在后台写代码就可以了啊GridView1.PageIndex = Convert.toInt32(TextBox1.Text);
Bind();大致思路就是这样子的啊

Answer 11

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？

Answer 12

很简单，加入按钮和文本控件后  在按钮点击事件中加入如下代码 可实现跳转到某页。
        protected void btnLoginPage_Click(object sender, EventArgs e)
        {
            if (txtPage.Text == "" || txtPage.Text == null)
            { }
            else
            {
                int page = Convert.ToInt32(txtPage.Text.Trim());
                if (page < 0 || page > gridView.PageCount)
                {
                    //超出总页面
                    gridView.PageIndex = page;
                }
                else
                {
                    gridView.PageIndex = page - 1;
                    bind();
                }
            }
        }

http://www.webdiyer.com/Controls/AspNetPager AspNetPager分页控件能满足你的要求，看看吧，很好的分页控件，还可以随意改变样式。
