Examples

下面的示例演示如何创建一个 NavigationWindowThe following example shows how to create a NavigationWindow.

<NavigationWindow

Remarks

NavigationWindow 派生自 Window,并将其扩展为导航到并显示内容的功能。NavigationWindow derives from Window and extends it with the ability to navigate to and display content.

内容可以是任何 .NET Framework 对象或 HTML 文件。Content can be any .NET Framework object or HTML file. 但一般情况下,Page 对象是打包内容以便导航的首选方式。In general, however, a Page object is the preferred way to package content for navigation.

通过使用所需内容的 URI 设置 Source 属性,可以导航到内容。Content can be navigated to by setting the Source property with the URI for the desired content. 此外,还可以使用 Navigate 方法的以下重载之一导航到内容:Additionally, content can be navigated to by using one of the following overloads of the Navigate method:

按 URI 导航到内容后,NavigationWindow 将返回包含内容的对象。When content is navigated to by URI, NavigationWindow will return an object that contains the content.

Note

导航依据 URI 还支持导航到内容片段。Navigation by URI also supports navigation to a content fragment. 请参阅 FragmentNavigationSee FragmentNavigation.

此外,还可以通过使用接受对象的 Navigate 方法重载之一来导航内容:Alternatively, content can be navigated to by using one of the Navigate method overloads that accepts an object:

导航的生存期可通过以下事件进行跟踪:The lifetime of a navigation can be tracked through the following events:

并非每次发生导航时都会引发所有事件;引发的事件集由发生的导航类型(内容或内容片段)以及导航完成方式(取消、停止或失败)决定。Not all events are raised each time that a navigation occurs; the set of events that are raised is determined by the type of navigation that occurs (content or content fragment) and how the navigation completes (canceled, stopped, or failed).

下图说明了这些事件将激发的顺序:The following figure illustrates the sequence in which these events will fire:

页面导航流程图Page navigation flow chart

导航期间或之后 NavigationWindow 提供有关要导航到的内容的信息,包括要导航到的内容的 URI (Source)、当前内容的 URI (CurrentSource)以及包含导航到的内容的对象(Content)。During or after a navigation, NavigationWindow provides information about the content that is being navigated to, including the URI of the content being navigated to (Source), the URI of the current content (CurrentSource), and an object that contains the content that was navigated to (Content).

导航至内容时,NavigationWindow 会将导航记录为导航历史记录中的条目。When content is navigated to, NavigationWindow records the navigation as an entry in navigation history. 当出现新的导航时,通过调用 Navigate 方法,或者通过调用 GoForward导航到前进导航历史记录中的条目,可以将条目添加到后退导航历史记录中。An entry is added to back navigation history when either a new navigation occurs, by calling the Navigate method, or by navigating to an entry in forward navigation history, by calling GoForward. 通过导航到后退导航历史记录中的条目(通过调用 GoBack),将条目添加到前进导航历史记录中。An entry is added to forward navigation history by navigating to an entry in back navigation history, by calling GoBack. CanGoBackCanGoForward 报告是否分别包含向后导航历史记录和前进导航历史记录中的条目。CanGoBack and CanGoForward report whether there are entries in backward and forward navigation history, respectively.

第一次从另一段内容导航到一个内容时,NavigationWindow 会自动显示允许用户在导航历史记录中来回导航的导航用户界面。The first time that one piece of content is navigated to from another piece of content, NavigationWindow automatically displays a navigation UI that allows users to navigate back and forwards through navigation history. 可以通过设置 "ShowsNavigationUI" 属性来配置显示导航 UI 的时间。You can configure when the navigation UI is shown by setting the ShowsNavigationUI property.

可以通过调用 RemoveBackEntry来移除后退导航历史记录中的最新条目。The most recent entry in back navigation history can be removed by calling RemoveBackEntry.

NavigationWindow 不会在导航历史记录中存储内容对象的实例。NavigationWindow does not store an instance of a content object in navigation history. 相反,每次使用导航历史记录导航到内容对象时,NavigationWindow 都将创建该对象的新实例。Instead, NavigationWindow creates a new instance of the content object each time it is navigated to by using navigation history. 此行为旨在避免在将大量内容导航到时消耗过多的内存。This behavior is designed to avoid excessive memory consumption when large numbers and large pieces of content are being navigated to. 因此,不会从一个导航到下一个导航来记住内容的状态。Consequently, the state of the content is not remembered from one navigation to the next. 不过,WPF 提供了多种方法,通过这些方法,你可以在导航历史记录中存储一段内容的状态。However, WPF provides several techniques by which you can store a piece of state for a piece of content in navigation history.

使用 AddBackEntry,还可以记住单个页面实例的多个状态集。Using AddBackEntry, you can also remember multiple sets of state for a single page instance.

NavigationWindow 是 WPF 中的两个导航器之一,另一个则是 FrameNavigationWindow is one of two navigators in WPF, the other being Frame. 从本质上讲,导航器是一个支持导航和导航历史记录的类。Essentially, navigator is a class supports navigation and navigation history. 直观地 XBAPXBAPs 使用 Internet Explorer 7Internet Explorer 7 导航器来提供集成的用户体验。Visually, XBAPXBAPs use Internet Explorer 7Internet Explorer 7 as a navigator, to provide an integrated user experience. XBAPXBAPs 实际上使用 NavigationWindow 作为导航器;在 Internet Explorer 7Internet Explorer 7 中运行的 XBAPXBAPMainWindow 属性将返回对 NavigationWindow的引用,并且由 NavigationWindow 管理的导航历史记录与 Internet Explorer 7Internet Explorer 7管理的导航历史记录集成。However, XBAPXBAPs actually use NavigationWindow as the navigator; the MainWindow property of an XBAPXBAP running in Internet Explorer 7Internet Explorer 7 will return a reference to the NavigationWindow, and the navigation history that is managed by the NavigationWindow is integrated with the navigation history that is managed by Internet Explorer 7Internet Explorer 7.

内容模型:NavigationWindowContentControl,这意味着 NavigationWindow 可以包含文本、图像或面板等内容。Content Model: NavigationWindow is a ContentControl, which means that NavigationWindow can contain content such as text, images, or panels. 此外,NavigationWindow 是根元素,因此,不能是另一个元素的内容的一部分。Also, NavigationWindow is a root element and, consequently, cannot be part of another element's content. 有关 Button的内容模型的详细信息,请参阅WPF 内容模型For more information about the content model for Button, see WPF Content Model.

自定义 System.windows.navigation.navigationwindow> 控件Customizing the NavigationWindow Control

若要对多个 NavigationWindow 控件应用相同的属性设置,请使用 Style 属性。To apply the same property settings to multiple NavigationWindow controls, use the Style property. 您可以修改默认 ControlTemplate 以使控件具有独特的外观。You can modify the default ControlTemplate to give the control a unique appearance. 有关创建 ControlTemplate的详细信息,请参阅通过创建 System.windows.controls.controltemplate> 自定义现有控件的外观For more information about creating a ControlTemplate, see Customizing the Appearance of an Existing Control by Creating a ControlTemplate. 若要查看特定于 NavigationWindow的部分和状态,请参阅System.windows.navigation.navigationwindow> 样式和模板To see the parts and states that are specific to the NavigationWindow, see NavigationWindow Styles and Templates.

此控件的依赖属性可能由控件的默认样式设置。Dependency properties for this control might be set by the control's default style. 如果按默认样式设置属性,则当控件出现在应用程序中时,属性可能会更改为默认值。If a property is set by a default style, the property might change from its default value when the control appears in the application. 默认样式取决于应用程序运行时使用的桌面主题。The default style is determined by which desktop theme is used when the application is running. 有关详细信息,请参阅默认的 WPF 主题For more information, see Default WPF Themes.

Note

只有视觉对象属性已存在于控件的默认模板中并且已使用 TemplateBinding 设置时,设置该属性才有效。Setting a visual property only has an effect if that property is both present in the control's default template and is set by using a TemplateBinding. 通过创建 ControlTemplate 自定义现有控件的外观一文的更改控件的视觉结构部分可以找到视觉属性列表。You can find a list of visual properties in the Changing the Visual Structure of a Control section in the Customizing the Appearance of an Existing Control by Creating a ControlTemplate article.
