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> 页 <!--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(); }
