要在ASP.NET中访问DataGrid中所有控件的值，可以遍历DataGrid中每个控件：下面就是实现这一功能的aspx代码和脚本代码【VB.NET】：
<![CDATA[<%@ Page Language="vb" AutoEventWireup="false" Codebehind="DataGridAccessValues.aspx.vb" Inherits="aspxWeb.DataGridAccessValues"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"><HTML><HEAD></HEAD><body><form runat="server" ID="Form1"><ItemStyle verticalalign="Top"></ItemStyle><Columns></asp:BoundColumn> <ItemTemplate> ' runat="server"></asp:TextBox> </ItemTemplate></asp:TemplateColumn> <ItemTemplate> ' runat="server"></asp:CheckBox> </ItemTemplate></asp:TemplateColumn> <ItemTemplate> C#</asp:ListItem> C++</asp:ListItem> VB</asp:ListItem> SQL Server</asp:ListItem> </asp:CheckBoxList> </ItemTemplate></asp:TemplateColumn> <ItemTemplate> 1 Year</asp:ListItem> 3 Year</asp:ListItem> 5 Year</asp:ListItem> 10 Year</asp:ListItem> </asp:RadioButtonList> </ItemTemplate></asp:TemplateColumn> <ItemTemplate> HighSchool</asp:ListItem> Graduate</asp:ListItem> Masters</asp:ListItem> PHD</asp:ListItem> </asp:DropDownList> </ItemTemplate></asp:TemplateColumn></Columns></asp:DataGrid><br></asp:Button><br></asp:Label></form></body></HTML>]]>后端代码：
