gridview 分页（自定义)

(1) 在default.aspx 中

<PagerTemplate>
           <table width="100%">
            <tr><td style="text-align:right">            
                <asp:LinkButton ID="lkbFirst" runat="server" CommandArgument="First" CommandName="Page" Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>" OnCommand="PageChange" text="首 页"></asp:LinkButton> &nbsp;
                <asp:LinkButton ID="lkbPre" runat="server" CommandArgument="Pre" CommandName="Page" Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>" OnCommand="PageChange" text="上一页" ></asp:LinkButton> &nbsp;
                <asp:LinkButton ID="lkbNext" runat="server" CommandArgument="Next" CommandName="Page" Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>" OnCommand="PageChange" text="下一页"></asp:LinkButton> &nbsp;
                <asp:LinkButton ID="lkbLast" runat="server" CommandArgument="Last" CommandName="Page" Enabled="<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>" OnCommand="PageChange" text="尾 页"></asp:LinkButton>
            </span>
           <%--
                调转到&nbsp;<asp:TextBox ID="tbxPage" runat="server" Width="20px"></asp:TextBox>&nbsp;页&nbsp;&nbsp;
                <asp:LinkButton ID="lkbGoPage" runat="server" CommandName="GoPage" OnCommand="GoToPage">GO</asp:LinkButton>&nbsp;&nbsp;--%>
           
          
                第&nbsp;<asp:Label ID="lblCurrent" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label>&nbsp;页/
                共&nbsp;<asp:Label ID="lblTotal" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label>&nbsp;页
             </td></tr>
           </table>           
            </PagerTemplate>

 

 

(2) C# 中增加

    public void PageChange(object sender, System.Web.UI.WebControls.CommandEventArgs e)
    {
        int currentIndex = 0;
        if (e.CommandArgument.ToString() == "First")
            currentIndex = 0;
        else if (e.CommandArgument.ToString() == "Pre")
            currentIndex = GridView1.PageIndex > 0 ? GridView1.PageIndex - 1 : 0;
        else if (e.CommandArgument.ToString() == "Next")
            currentIndex = GridView1.PageIndex == GridView1.PageCount - 1 ? GridView1.PageIndex : GridView1.PageIndex + 1;
        else if (e.CommandArgument.ToString() == "Last")
            currentIndex = GridView1.PageCount - 1;
        GridView1.PageIndex = currentIndex;
        bind();
    }

//指到指定的页数

    //public void GoToPage(object sender, System.Web.UI.WebControls.CommandEventArgs e)
    //{
    //    GridViewRow pagerRow = GridView1.BottomPagerRow;    //控件中的底部页导航行
    //    TextBox tbxSearch = (TextBox)pagerRow.Cells[0].FindControl("tbxPage");

    //    int page = Convert.ToInt32(tbxSearch.Text.Trim()) - 1;

    //    if (tbxSearch !=null)
    //    {
    //        if (tbxSearch.Text.Trim() != "")
    //            page = int.Parse(tbxSearch.Text.Trim()) - 1;
    //        if (page < 0) { page = 0; }
    //        if (page > GridView1.PageCount)
    //        {
    //            page = GridView1.PageCount;
    //        }
    //    }
    //    GridView1.PageIndex = page;
    //    bind();
    //}

 

    public void bind()
    {
        GridView1.DataBind(); //Gridview的数据源绑定函数，自己写吧！
    }
