推荐答案

母版页和内容页不共享相同的ViewState。
如果你正试图从内容页的东西传递给母版页有几个选择：

- 使用this.Context.Items该HTTP请求
- 使母版页上的公共属性，从内容页投this.Master到母版页类，并设置属性

- 使用会话

Master pages and content pages do not share the same ViewState. If you are trying to pass something from the content page to the master page there are a couple of alternatives:
- use this.Context.Items that is common to the entire site during an HTTP request
- make a public property on the master page, cast this.Master from the content page to the master page class and set the property
- use Session
