The view provides two services to the user: presenting data and interacting with data. The former involves reading data and displaying it in a certain format, whereas the latter implies editing existing or adding new data. This chapter will focus on the methods available to developers for displaying data in WPF or Silverlight controls. We will attempt to remain entirely declarative, binding the controls to data via XAML.

Interestingly enough, WPF provides two classes that let you browse through the logical and visual trees. These classes are System.Windows.LogicalTreeHelper and System.Windows.Media.VisualTreeHelper. You ve already seen the LogicalTreeHelper in 2, where it allowed you to hook up event handlers in a WPF application with a dynamically loaded XAML document. The LogicalTreeHelper provides the relatively sparse set of methods listed in Table 17-1. Although these methods are occasionally useful, in most cases you ll use the methods of a specific FrameworkElement instead.

FindLogicalNode()

Finds a specific element by name, starting at the element you specify and searching down the logical tree. Scrolls an element into view (if it s in a scrollable container and isn t currently visible). The FrameworkElement.BringIntoView() method performs the same trick. Gets the parent element of a specific element. Gets the child element of a specific element. As you learned in 2, different elements support different content models. For example, panels support multiple children, while content controls support only a single child. However, the GetChildren() method abstracts away this difference and works with any type of element.

Figure 13-1. Sequence for logging into a website with an information card Each of the steps in Figure 13-1 is described in the following list: 1. The user goes to the login page for a website. 2. An HTTP GET is sent to the relying party for the login page. 3. An HTML login page with the OBJECT tag is returned to the browser.

GetParent() GetChildren()

The VisualTreeHelper provides a few similar methods GetChildrenCount(), GetChild(), and GetParent() along with a small set of methods that are designed for performing lower-level drawing. (For example, you ll find methods for hit testing and bounds checking, which you considered in 14.) The VisualTreeHelper also doubles as an interesting way to study the visual tree in your application. Using the GetChild() method, you can drill down through the visual tree of any window and display it for your consideration. This is a great learning tool, and it requires nothing more than a dash of recursive code.

In order to facilitate this new paradigm in databinding, the very lowest-level objects have to be enhanced. The functionality of System.Object subclasses, and the vanilla property system afforded to them, was not enough to support the databinding that WPF s developers had in mind. This resulted in the addition of System.Windows.DependencyObject and System.Windows.DependencyProperty, to handle to extra functionality required of objects and properties, respectively, that participated in the new databinding system.

Figure 17-4 shows one possible implementation. Here, a separate window displays an entire visual tree, starting at any supplied object. In this example, another window (named SimpleWindow), uses the VisualTreeDisplay window to show its visual tree.

Here, a window named Window1 contains a Border, which in turn holds an AdornerDecorator. (The AdornerDecorator class adds support for drawing content in the adorner layer, which is a special invisible region that overlays your element content. WPF uses the adorner layer to draw details such as focus cues and drag-and-drop indicators.) Inside the AdornerDecorator is a ContentPresenter, which hosts the content of the window. That content includes StackPanel with two Button controls, each of which comprises a ButtonChrome (which draws the standard visual appearance of the button) and a ContentPresenter (which holds the button content). Finally, inside the ContentPresenter of each button is a TextBlock that wraps the text you see in the window.

Note In this example, the code builds a visual tree in another window. If you place the TreeView in the same window

as the one you re examining, you d inadvertently change the visual tree as you fill the TreeView with items.
