您需要@MasterPage指令..



像这样：

You need the @MasterPage Directive..

Like this:

<%@ MasterType virtualPath="~/MasterPage.master"%>

看看这个：以编程方式使用ASP.NET母版页 [ ^ ]

在您的内容页面中添加MasterPageFile =〜/ Masterpage.Master

by adding MasterPageFile="~/Masterpage.Master" in your content page

假设您要访问TextBox Maste r页面上的内容页面..可以像这样访问

Suppose you want to access the TextBox of Master page on the Content page..it can be access like this

TextBox txtBox = this.Master.Master.FindControl("txtMasterPageMaster") as TextBox;
