《Windows.8中XAML初级读本（入门）》是由Jesse Liberty所著的一本专为Windows 8平台开发者设计的教材。本书在2012年首次出版，版权受到严格的保护，所有内容，包括文字、插图、翻译权、再版、重用、朗诵、广播、微缩复制、电子适应、计算机软件使用以及任何尚未知晓或未来开发的类似技术方法，均受法律限制。根据版权法，仅限于对作品进行简短摘录，用于评论或学术分析，且仅限于供购买者个人计算机系统使用。未经Springer出版社许可的复制行为是违法的。书中深入浅出地介绍了XAML（Extensible Application Markup Language）在Windows 8中的应用。作为Windows 8应用程序开发的基础，XAML是一种基于XML的语言，它使得开发者能够创建具有丰富的用户界面和交互体验的应用程序，尤其是在 Metro风格的应用中，这种语言尤为重要。XAML允许开发者定义界面元素的布局、样式、数据绑定和事件处理，从而实现了高效、灵活的设计。本书的内容可能涵盖以下知识点： 1. XAML基础：章节会从基本概念入手，解释什么是XAML，它与HTML、CSS等前端语言的区别，以及为何在Windows 8中选择XAML作为主要界面描述语言。 2. 控件与布局：介绍Windows 8中常见的控件类型，如Button、Grid、StackPanel等，并讲解如何使用它们构建直观的用户界面。还会讨论布局策略，如何控制元素在屏幕上的位置和大小。 3. 数据绑定：演示如何通过XAML将用户界面元素与背后的业务逻辑连接起来，实现数据的双向同步，提升用户体验。 4. 样式与主题：讲解如何使用XAML样式和主题来统一应用程序的外观和感觉，增强品牌识别度。 5. 事件处理与交互：介绍如何通过XAML处理用户交互，如按钮点击、滑动、触摸输入等，以及响应式设计的重要性。 6. 混合式应用开发：如果适用于Windows 8.1 Universal Apps，可能会探讨如何在XAML中集成原生代码，实现更复杂的功能。 7. 最佳实践与性能优化：提供开发者实用的技巧，帮助他们编写高效的XAML代码，提高应用程序的性能和响应速度。 8. 项目示例与实战演练：书中会包含多个实际项目的示例，让读者通过动手实践来巩固理论知识。《Windows.8中XAML初级读本》是一本实用且深入的教程，对于想要进入Windows 8开发领域，尤其是对XAML感兴趣的新手来说，是不可或缺的学习资源。通过阅读这本书，读者将掌握Windows 8平台下XAML的精髓，为自己的开发工作打下坚实的基础。

</Page>

The first element is of type Page and it represents the page itself. On line 2,

the class for this page (MainPage) is identified, complete with its full namespace (see

the “XML Namespaces” sidebar). Because the Page is a control, its default setting for

IsTabStop is true. Since you don’t want the page itself to be in the list of tab stops in

the page, you set IsTabStop to false.

This is followed by the identification of a number of useful namespaces. Note that

most have the syntax xamlns:namespaceName such as xmlns:local or xmlns:x but the

first (http://schemas.microsoft.com/winfx/2006/xaml/presentation) does not have the

colon and namespace prefix and thus is the default namespace for controls on this page.

XML NAMESPACES

Generally, namespaces are a way to divide up and segregate the identifiers used in a pro-

gram. In XAML, XML namespaces are often used to differentiate controls from different

vendors. For example, when you declare an instance of a TextBlock, you are really de-

fining an instance of the TextBlock control provided by Microsoft, as identified in the

default namespace. It is possible and legal (if confusing) to declare a TextBlock in your

own library, and the two will be distinguished by the XML namespace prefix.

If you purchase third party controls (such as those sold by Telerik and other vendors),

the controls will be referenced through the vendor’s namespace, such as <tel-

erik:RadSlider> and this namespace will be identified at the top of the page with a

statement like

xmlns:telerik="using:Telerik.UI.Xaml.Controls"

This declares the namespace telerik for use in the remainder of the page.

Below the namespace definitions is the declaration of a Grid. A Grid is one of

numerous types of panels (see Chapter 3) that you can use in XAML to organize the

layout of the controls on your page. A Grid typically has rows and columns defined.

In this case, however, no rows or columns have been defined yet so the default Grid

consists of a single giant cell.

The background color for the Grid is set to a StaticResource named Ap-

plicationPageBackgroundThemeBrush. Static resources will be described in

detail later (see Chapter 5), but they are a common way to reuse resources such as

This is a considerably more complex set of code. You are not using the rows and

columns of the grid, but rather you’ve placed a StackPanel directly into the grid. A

StackPanel, as its name implies, stacks one object atop or next to another. The de-

fault orientation for a StackPanel is vertical (one on top of another) but you can set

it to horizontal.

Inside your StackPanel you placed two more StackPanel (with horizontal

orientations) and a Button. The effect, as shown in Figure 1-3, is to have an outer

stacked panel with two inner stacked panels, and then a button below.

The inner StackPanels are marked with orientation set to horizontal, and in-

side each is a TextBlock and a TextBox, aligning these two next to one another. The

StackPanels have their vertical and horizontal alignments set. The possible values

for horizontal and vertical alignment are from enumerated constants (e.g., Left, Center,

Right, Stretch) and thus are shown by IntelliSense (Microsoft’s implementation of auto-

completion), making coding with these values easier. You’ll find that IntelliSense is per-

vasive in Visual Studio programming of XAML.

Notice that the TextBoxes have Name attributes; this allows you to refer to

them in the code. Any XAML object that is given a name can be referred to in the code.

However, you do not have to declare controls in the code; the XAML declaration is

enough to establish the name of the object. You’ll see this in just a moment when you ex-

amine the event handler for the button click event. Each TextBox also has its Width

and Height set as the TextBox does not (yet) have text, and thus cannot size itself

automatically.

At the bottom of the outer-most StackPanel you’ve added a Button. It too

has a name, as you’ll refer to it in code, and a Width, FontSize, etc. The Button

has a Content attribute, which can be any form of content, though the most common

is to use a string with the text you want to appear in the Button.

Event Handling

Entering text, however, won’t do much good unless you can do something with the text

that is entered. This is where event handling comes in.

The Button also has an event, Click, and when you add the Click event, Visual

Studio also adds an event handler. If you allow Visual Studio to do so, it will name the

event handler for you and create a stub of the event handler in the codebehind file. The

codebehind file has the same name as the XAML file but with the extension .cs for C#

or .vb for Visual Basic.
