  • ASP.NET GridView利用PagerTemplate自定义分页

    前端:

    <asp:GridView ID="GridView1" runat="server" AllowPaging="True">
    <PagerTemplate>
    当前第:
    <%--//((GridView)Container.NamingContainer)就是为了得到当前的控件--%>
    <asp:Label ID="LabelCurrentPage" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label>
    页/共:
    <%--//得到分页页面的总数--%>
    <asp:Label ID="LabelPageCount" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label>

    <%--//如果该分页是首分页,那么该连接就不会显示了.同时对应了自带识别的命令参数CommandArgument--%>
    <asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page"
    Visible='<%#((GridView)Container.NamingContainer).PageIndex != 0 %>'>首页</asp:LinkButton>
    <asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev"
    CommandName="Page" Visible='<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>'>上一页</asp:LinkButton>
    <%--//如果该分页是尾页,那么该连接就不会显示了--%>
    <asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page"
    Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>下一页</asp:LinkButton>
    <asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page"
    Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>尾页</asp:LinkButton>
    转到第
    <asp:TextBox ID="txtNewPageIndex" runat="server" Width="20px" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>' />页
    <%--//这里将CommandArgument即使点击该按钮e.newIndex 值为3 --%>
    <asp:LinkButton ID="btnGo" runat="server" CausesValidation="False" CommandArgument="-2"
    CommandName="Page" Text="GO" />
    </PagerTemplate>
    </asp:GridView>

    C#后台

    // EmployeeGrid.PageIndex = e.NewPageIndex;
    // InitialGridView_EmployeeDirectory();
    // 得到该控件
    GridView theGrid = sender as GridView;
    int newPageIndex = 0;
    if (e.NewPageIndex == -3)
    {
    //点击跳转按钮
    TextBox txtNewPageIndex = null;

    //GridView较DataGrid提供了更多的API,获取分页块可以使用BottomPagerRow 或者TopPagerRow,当然还增加了HeaderRow和FooterRow
    GridViewRow pagerRow = theGrid.BottomPagerRow;

    if (pagerRow != null)
    {
    //得到text控件
    txtNewPageIndex = pagerRow.FindControl("txtNewPageIndex") as TextBox;
    }
    if (txtNewPageIndex != null)
    {
    //得到索引
    newPageIndex = int.Parse(txtNewPageIndex.Text) - 1;
    }
    }
    else
    {
    //点击了其他的按钮
    newPageIndex = e.NewPageIndex;
    }
    //防止新索引溢出
    newPageIndex = newPageIndex < 0 ? 0 : newPageIndex;
    newPageIndex = newPageIndex >= theGrid.PageCount ? theGrid.PageCount - 1 : newPageIndex;
    //得到新的值
    theGrid.PageIndex = newPageIndex;
    //重新绑定

    GridView绑定程序;
