VS 2012中的访问修饰符& Windows 8 App？ [英] Access modifiers in VS 2012 & Windows 8 App?
问题描述
嗨伙计们，
我有一个完成这个月底的项目。
多数民众赞成关于Windows 8 Metro中的新闻应用程序。
我使用标准网格应用程序进行项目。
在SampleDataSource.cs文件中，我编写了下面编写的代码。但是，我无法使用下面给出的代码访问GridView控件。
myGrid.Items.Add（Convert.ToString （reader.ReadElementContentAsString（）））; // myGrid = GridView。
我怎么能压倒这个问题？正如你们许多人所知，Windows Form Application具有Access Modifiers的功能，可以通过设置公共来实现任何控制。
感谢您的支持回答我问的问题。
此致，
H.BERAT YILDIRIM
hi guys,
I ve one project to finish end of this montth.
Thats about "news application" in Windows 8 Metro.
Im using standart Grid App for porject.
In SampleDataSource.cs file , I've written the code written below. However , I can't access the GridView Control by using the code given below.
myGrid.Items.Add(Convert.ToString(reader.ReadElementContentAsString())); // myGrid = GridView.
How can i overwhelm ths problem ? As many of you know , Windows Form Application has the propery of Access Modifiers to reach any control by setting public.
Thanks for your answer for the question I asked.
Sincerely,
H.BERAT YILDIRIM
推荐答案
仅仅因为你 可以 做某事，并不代表你 做点什么。
将控件设置为public是一个非常糟糕的主意 - 它违反了原则OOP并且使您的代码难以修改，因为任何外部类都可以使用内部控件。
相反，使用属性和事件来获取/设置数据并发出信号表明它是可用。
我无法从你的问题中确切地知道你需要走哪条路，但是应该在这里介绍：
< a href =http://www.codeproject.com/Tips/548052/Transferring-information-between-two-forms-Part-1>转换器两种表格之间的信息，第1部分：父母与子女 [ ^ ]
在两个表格之间传递信息，第2部分：孩子到父母 [ ^ ]
在两种形式之间传递信息，第3部分：儿童到儿童 [ ^ ]
它们针对表单，但同样的原则也适用于UserControls：包含Us的表单（或另一个UserControl） erControl是父级，UserControl是子级。
Just because you can do something, doesn't mean you should do something.
Setting controls aspublicis a very poor idea - it violates the principles of OOP and makes your code difficult to modify as any outside class could have used internal controls.
Instead, use properties and events to get / set data and signal that it is available.
I can't tell from your question exactly which way you need to go, but it should be covered here:
Transferring information between two forms, Part 1: Parent to Child[^]
Transferring information between two forms, Part 2: Child to Parent[^]
Transferring information between two forms, Part 3: Child to Child[^]
They are aimed at forms, but the same principle applies to UserControls as well: a form (or another UserControl) containing a UserControl is the parent, the UserControl is the child.
