c#怎么实现下一页

Answer 1

1. 参考下列C# 代码： 

2. <PagerTemplate>      <table>        <tr>          <td style="text-align: right"> 第<asp:Label ID="lblPageIndex" runat="server" Text="<%#((GridView)Container.Parent.Parent).PageIndex + 1 %>"></asp:Label>页           共<asp:Label ID="lblPageCount" runat="server" Text="<%# ((GridView)Container.Parent.Parent).PageCount %>"></asp:Label>页           <asp:LinkButton ID="btnFirst" runat="server" CausesValidation="False" CommandArgument="First" CommandName="Page" Text="首页"></asp:LinkButton>          <asp:LinkButton ID="btnPrev" runat="server" CausesValidation="False" CommandArgument="Prev"          CommandName="Page" Text="上一页"></asp:LinkButton>           <asp:LinkButton ID="btnNext" runat="server" CausesValidation="False" CommandArgument="Next"            CommandName="Page" Text="下一页"></asp:LinkButton>             <asp:LinkButton ID="btnLast" runat="server" CausesValidation="False" CommandArgument="Last"            CommandName="Page" Text="尾页"></asp:LinkButton>          <asp:TextBox ID="txtNewPageIndex" runat="server" Text="<%# ((GridView)Container.Parent.Parent).PageIndex + 1%>" Width="20px"></asp:TextBox>          <asp:LinkButton ID="btnGo" runat="server" CausesValidation="False" CommandArgument="-1" CommandName="Page" Text="GO"></asp:LinkButton>         </td>      </tr>    </table></PagerTemplate>

3.  protected void PageIndexChanging(object sender, GridViewPageEventArgs e)    {        GridView gvw = (GridView)sender;        if (e.NewPageIndex < 0)        {            TextBox pageNum = (TextBox)gvw.BottomPagerRow.FindControl("txtNewPageIndex");            int Pa = int.Parse(pageNum.Text);            if (Pa <= 0)            {                gvw.PageIndex = 0;            }            else            {                gvw.PageIndex = Pa - 1;            }        }        else        {            gvw.PageIndex = e.NewPageIndex;        }        GetBind();//你绑定数据的方法    }

    

Answer 2

既然很急就用最简单的

一个Gridview控件,AllowPage 属性设为ture

pagechangeing 事件代码(大概)
this.gridview.pageindex=e.newpageindex
page.databind()

一个sqldatasource控件,按照步骤得到相关数据

设置Gridview的数据源为刚建好的SqlDataSource

有Button 的话就用Gridview.Pageindex的这个属性
