可以从内容页面访问母版页的元素吗?

Can the elements of the Master Page be accessed from the Content Page?

假设我有从MasterPage1继承的MasterPage1和ContentPage1，并且MasterPage1有一个按钮:Button1.

Lets say I have MasterPage1 and ContentPage1 that inherits from the MasterPage1, and the MasterPage1 has a button: Button1.

我可以从内容页面更改该按钮的属性，例如使Button1不可见，不活动等吗?我该怎么做?

Can I change the property of that button from the content page, for example to make Button1 invisible, inactive etc? How can I accomplish this?

推荐答案

您必须在页面/用户控件标记中放置对MasterPage的引用.

You have to put a reference to the MasterPage in your page/user control markup.

<%@ Reference VirtualPath="..." %>

然后，在后面的代码中，只需将Page.MasterPage转换为MasterPage并访问其属性.

Then in the code-behind, you just cast the Page.MasterPage to your MasterPage and access its properties.

MyMasterPage myMasterPage = (MyMasterPage)Page.Master;
