DetailsViewMode

使用 ChangeMode 方法以编程方式在编辑、插入和只读模式间切换 DetailsView 控件。此方法还将 CurrentMode [ http://msdn2.microsoft.com/zh-cn/library/system.web.ui.webcontrols.detailsview.currentmode.aspx ] 属性更新为指定模式。下表列出了不同的模式值。

 

模式

说明

DetailsViewMode.Edit

DetailsView 控件处于编辑模式，这样用户就可以更新记录的值。

DetailsViewMode.Insert

DetailsView 控件处于插入模式，这样用户就可以向数据源中添加新记录。

DetailsView.ReadOnly


DetailsView 控件处于只读模式，这是通常的显示模式。

下面的代码示例演示如何使用 ChangeMode 方法在每次用户导航到另一条记录时将 DetailsView 控件返回到只读模式。

C#
复制代码
<%@ Page language="C#" %>

<script runat="server">

  void CustomerDetailView_PageIndexChanged(Object sender, EventArgs e)
  {
    // By default, if the DetailsView control is in edit mode and
    // user navigates to another page, the DetailsView control
    // remains in edit mode. In this example, the ChangeMode 
    // method is used to put the DetailsView control in read-only  
    // mode whenever the user navigates to another record.
      CustomerDetailView.ChangeMode(DetailsViewMode.ReadOnly);
  }

</script>

  <body>
    <form id="Form1" runat="server">
