要在GridView中加入
//实现分页
AllowPaging=“true”
//一页数据10行
PageSize=“10”
在服务器事件里
protected void gvwDesignationName_PageIndexChanging(object sender, GridViewPageEventArgs e) {
gvwDesignationName.PageIndex=e.newIndex; bingDesignatioonName(); }
显示分页的通用模板
<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="-2" CommandName="Page" Text="GO" /> </PagerTemplate>
对应事件中的代码:
protected void gvwDesignationName_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 bingDesignatioonName(); }
