从模块访问母版页属性 [英] Accessing a Master Page Property from a Module
问题描述
我一直在阅读斯科特艾伦关于母版页的文章（http：//
odetocode.com/Articles/450.aspx）但我遇到了问题
理解一个概念。具体来说，我在我的母版页上创建了一个属性
（称为CurFlag），可以从内容访问
页面，但不能从单独的代码模块访问。
我在VB代码模块中尝试过这样的事情：
将myMaster视为MasterPage = CType（ProjectMgmt.Master，
MasterPage）
myMaster.CurFlag =" value"
....但这只是给我一个参考非共享成员要求
一个对象引用第一行出错。请原谅我的无知，
但是我的语法是正确的，还是我需要在母版页上添加额外的东西，以便我的模块看到这个母版页？
我会很感激任何建议。
谢谢。
I have been reading Scott Allen''s article on Master Pages (http://
odetocode.com/Articles/450.aspx) but I am having problems
understanding a concept. Specifically, I have created a property
(called "CurFlag") on my master page that can be accessed from content
pages, but not from separate code modules.
I tried doing something like this in my VB code module:
Dim myMaster As MasterPage = CType(ProjectMgmt.Master,
MasterPage)
myMaster.CurFlag = "value"
....but this just gets me an "Reference to a non-shared member requires
an object reference" error on the first line. Forgive my ignorance,
but is my syntax correct, or do I need to add something additional to
the master page so that my module "sees" this master page?
I would appreciate any suggestions.
Thank you.

首先必须将实例声明为对象变量，然后由变量名引用
。
Dim myMaster As MasterPage = new ProjectMgmt.Master
The instance must first be declared as an object variable and then
referenced by the variable name.
Dim myMaster As MasterPage = new ProjectMgmt.Master

首先必须将实例声明为对象变量，然后用变量名引用
。
Dim myMaster As MasterPage = new ProjectMgmt.Master-隐藏引用文字 -
- 显示引用文字 -
The instance must first be declared as an object variable and then
referenced by the variable name.
Dim myMaster As MasterPage = new ProjectMgmt.Master- Hide quoted text -
- Show quoted text -
等等......必须有一个班级名称
我认为，ProjectMgmt.Master是你母版页面的名称
Wait... there must be a name of the class
I think, ProjectMgmt.Master is the name of your Master page
Kirk，
不确定你想要实现什么 - 为什么你需要访问
主页（一般来说）页面特定 - 因为不同的页面可能有一个模块的不同主页页面？您只需要访问
特定页面的主页面实例 - 在这种情况下，您需要一个
引用页面实例（或任何控件）页面）或主人
本身。
如果您需要更改所有页面的主人 - 在主人内部进行，
你会得到它的参考。
如果你提供更多关于你想要达到的目标，它将更容易
更容易建议一个更好的方法来完成任务。
" Kirk"写道：
Kirk,
Not sure what are you trying to achieve - why would you need to access
master page (which is generally page specific - as different pages may have
different master pages) from a module? You will only want to access a
particular page''s master page instance - in this case you will need a
reference to the page instance (or any control on the page) or to the master
itself.
If you need to change your master for all page - do it inside your Master,
and you will have the reference to it.
If you provide a bit more on what you are trying to achieve, it will be
easier to suggest a better way to accomplish the task.
