Code-Behind 和 XAML 语言 XAML 语言包括语言级别功能,使得可以从标记文件端将代码文件与标记文件相关联。 具体而言,XAML 语言定义x:Class 指令、x:Subclass 指令以及x:ClassModifier 指令的语言功能。 确切地说,应如何生成代码,以及如何集成标记和代码,不是 XAML 语言所指定的内容的一部分。 由 WPF 等框架决定如何...
最明顯的加強功能就是能夠同時使用「標記」(Markup) 和「程式碼後置」(Code-Behind) 來開發應用程式,ASP.NET 開發人員應該很熟悉這種開發方式。 一般來說,Extensible Application Markup Language (XAML) 標記是用來實作應用程式的外觀,而 Managed 程式語言 (程式碼後置) 則是用來實作其行為。 將外觀和行為分開來有...
WPF lets you develop an application using both markup and code-behind, an experience with whichASP.NETdevelopers should be familiar. You generally use XAML markup to implement the appearance of an application while using managed programming languages (code-behind) to implement its behavior. This sep...
In WPF, this behavior is implemented in code that is associated with markup. This type of code is known as code-behind. The following example shows the updated markup from the previous example and the code-behind: XAML Copy <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/...

public bool IsLoading { get { return _isLoading; } set { if ( value != _isLoading ) { _isLoading = value; FirePropertyChanged("IsLoading"); } } } Demo Project In order to demonstrate this solution, I have created a simple demo project (included in the attached source code projec...
In code-behind, theWindowclass must implement a constructor that calls theInitializeComponentmethod.InitializeComponentis implemented by the markup file's generatedpartialclass to register events and set properties that are defined in markup. Note
下面,我们不使用XAML和x:Name,使用Code-Behind和SomeWpfType.Name来测试一下。 namespaceCnblog {//使用Button的Name属性publicclassSetNameByCodeBehind : Window {publicSetNameByCodeBehind() {//Buttonsvarbutton1 =newButton { Name ="Button1"}; ...
If you are new to MVVM or need a refresher, take a moment to readan introduction to the MVVM pattern. In this post, I will assume you have a basic understanding of how MVVM works. If you don't need MVVM and just want to visualize your data in a code-behind, don’t worry—you ...
