使用PagerTemplate实现GridView分页

分页效果图:

 

 

 

 1. 添加GridView属性

  //实现分页

    AllowPaging="true"

    //一页数据10行

     PageSize="10"

  //分页时触发的事件

    OnPageIndexChanging="GridView1_PageIndexChanging"

 

2、在前面页面GridView中,添加PagerTemplate标签

<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="3"
                    CommandName="Page" Text="GO" />
            </PagerTemplate>

 

3、页面后台添加事件

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
        {
            
            // 得到该控件
            GridView theGrid = sender as GridView;
            int newPageIndex = 0;
            if (e.NewPageIndex == -3)
            {
                //点击了Go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;

            //重新绑定数据
            getInfo();
        }
