ASP.NET (C#) 

<%@ Page language="C#" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<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);
  }

注解

ChangeMode使用此方法以编程方式在编辑、插入和只读模式之间切换DetailsView控件。 此方法还会使用指定的模式更新 CurrentMode 属性。 下表列出了不同的模式值。

“模式” 说明
DetailsViewMode.Edit 控件 DetailsView 处于编辑模式，允许用户更新记录的值。
DetailsViewMode.Insert 控件 DetailsView 处于插入模式，允许用户向数据源添加新记录。
DetailsView.ReadOnly 控件 DetailsView 处于只读模式，这是正常的显示模式。
