2012年11月-.Net学习笔记-GridView-ASP.Net-(停止更新)

2012年11月-.Net学习笔记-GridView-ASP.Net-（更新）

1.快速写封装字段（set&get)：Ctrl+R，E +Enter+Enter

2.设置主键：DataKeyName = 要设为主键的字段

3.GridView绑定数据：

     GridView.DataSource = 数据源;

     GridView.DataBind();

  设置GridView分页：

      AllowPaging = "true";

      PageSize = 每一页显示的行数

      还要设置下面的：

           protected void GridView1_PageIndexChanging(object sender,GridViewPageEvenArgs e)

   　　{

　　　　　　this.GridView1.PageIndex = e.NewPageIndex;

　　　　　　this.BindData();//重新绑定 自己写的方法

   　　} 

  还有删除和编辑的按钮的实现：

2.GridView无刷新分页的实现（UpdatePanel，ScriptManager）；

修改的前台代码 
 1 <body>
 2     <form id="form1" runat="server">
 3     <div>
 4         <asp:ScriptManager ID="scriptmanager1" runat="server"></asp:ScriptManager>
 5         <asp:UpdatePanel ID="updatepanel1" runat="server">
 6         <Triggers>
 7             <asp:AsyncPostBackTrigger ControlID="GridView1" EventName="PageIndexChanging" /><!--绑定分页事件-->
