DetailsView的简单使用

最近做一个东西用到DetailsView,所以看了一下资料,用了一下,以前也没用过这个控件,不过与GridView结合起来使用还不错的,因为GridView自带了增、删、改功能，但没有增加，DetailsView的结合就很好的粥补了这一缺点，也可以使GridView中查看单条数据记录的详细信息变是更加方便。

HTML中的代码：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

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

If you want to get the value in ReadOnly mode, it should be: DetailsView1.Rows[1].Cells[1].Text //"bpac" field data

If it is in edit mode, it should be: ((TextBox)DetailsView1.Rows[1].Cells[1].Controls[0]).Text //value in TextBox for "bpac" field

The Cells[0] is the headertext, Cells[1] is the bound value.
