理解Navigation导航框架Page类

最后更新于:2022-04-01 14:21:15

![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-03-18_56eb67c868925.jpg) 在“[Silverlight实例教程 - 理解Navigation导航框架Frame类](http://blog.csdn.net/jv9/article/details/6576016)” 介绍了Silverlight Navigation框架主要对象之一,Frame类,该类可以被简单的理解为Silverlight Navigation页面承载框架,框架中提供丰富的属性,方法和事件,从而实现Navigation框架功能。本篇将继续介绍Silverlight Navigation框架另外一个重要对象,Page类。 Page类,在Silverlight导航框架中主要功能是作为导航内容页载入到导航框架Frame类,从功能上来讲Page类是一个Silverlight UserControl, 而不同的是,Page类具备特定的导航属性和方法。 同样,从Asp.Net应用开发角度理解,Page类可以被看作为Master Page承载具体功能的子页面。  从Silverlight SDK中可以看出,Page类继承System.Windows.Controls.UserControl,也就是说Page类是一个用户控件类,可被任何ContentControl内容控件类(Frame类)承载显示。 ~~~ System.Object    System.Windows.DependencyObject      System.Windows.UIElement        System.Windows.FrameworkElement          System.Windows.Controls.Control             System.Windows.Controls.UserControl                 System.Windows.Controls.Page ~~~ 虽然Page类页面派生自UserControl,但是作为独立页面类,其具有特殊的页面命名空间,其页面初始化XAML代码如下: ~~~ <navigation:Page x:Class="SilverlightNavigationDemo.Home"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"     xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation"     mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480"     Title="首页"     Style="{StaticResource PageStyle}"> ~~~ 与UserControl页面不同的是<navigation:Page ..> </navigation:Page> . 值得注意的是,Silverlight导航框架Page类派生自UserControl,没有提供特定的事件,而该类继承了UserControl类事件。 从前文可知,在Silverlight导航框架中,Frame类功能是承载Page类,在整个导航过程中,两个类相互依存,而完整的导航进程事件运行顺序如下图:  ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-03-18_56eb67d018ce6.gif) 虽然Silverlight导航框架Page类没有定义专属事件,但是该类提供了专属的属性和方法,以供开发人员在导航过程中,对Page页面进行控制。 Silverlight导航框架常用**Page类属性**: <table style="BORDER-BOTTOM: medium none;

但是,两者也有不同之处,例如Frame类提供部分依赖属性,可供控件进行直接绑定和调用,例如IsEnabled, 通过该属性可以实现当前Frame是否可用。而NavigationService不能实现该绑定效果。 对于NavigationService类而言,其页面导航方法如上代码,值得注意的是该类包含两个特殊的方法,分别是Refresh()和StopLoading(), 这两个方法主要针对当前页面进行操作,其简单描述如下: **Refresh方法**,功能类似浏览器的刷新按钮,该方法将重载当前Page类页面,实现页面刷新效果,如果页面允许支持缓存,将从缓存中读取当前页面。 **StopLoading方法**,功能类似浏览器的停止按钮,该方法将停止正在运行的页面载入进程或者其他异步进程,在实际项目中,该方法并不常用。 **Page类的NavigationContext属性** Page 类提供的另外一个重要属性是NavigationContext属性,该属性提供一个NavigationContext对象,而该对象中包含两个常用属性分别是Uri和QueryString。在实际项目中,经常会使用NavigationContext.Uri获取当前URI路径字符串,使用 NavigationContext.QueryString获取导航页面传值。 例如: string uriText = String.Format(“/User.xaml?userID={0}&role={1}”, userID, userRole); mainFrame.Navigate(new Uri(uriText), UriKind.Relative); 执行以上代码,当前导航框架将访问如下地址: /User.xaml?userID=6&role=1 在User.xaml页面将使用NavigationContext.QueryString获取userID和userRole参数值,以获取详细用户信息。 ~~~ int userID, userRole; if (this.NavigationContext.QueryString.ContainsKey(“userID”))       userID = Int32.Parse(this.NavigationContext.QueryString[“userID”]); if (this.NavigationContext.QueryString.ContainsKey(“userRole”))       userRole = Int32.Parse(this.NavigationContext.QueryString[“userRole”]); ~~~ **Page类的NavigationCacheMode属性** Page 类的NavigationCacheMode属性是Silverlight导航框架重要属性之一,其功能可以保存导航页面状态。 NavigationCacheMode属性中包含有三个枚举成员,分别是Disabled,Required和Enabled,其含义分别是: NavigationCacheMode.Disabled: 不支持缓存页面,每次导航应用访问时创建 一个新的页面实例; NavigationCacheMode.Required: 支持缓存页面,并且每次导航应用访问时都重复利用该缓存实例,而且忽略Frame类中CacheSize属性设置大小; NavigationCacheMode.Enabled: 支持缓存页面,如果超过Frame类中CacheSize属性设置尺寸,则放弃保存缓存实例; 默认情况下,NavigationCacheMode为Disabled状态,也就是说,在Silverlight导航框架应用时,不记录任何信息到缓存。当NavigationCacheMode状态设置为Required后,每当用户结束一次导航操作,Frame类将保存页面对象到内存,当用户点击返回或者前进时,将重新载入保存的缓存状态到当前Page类页面,而当前Page类页面的构造函数不再执行,但是其Loaded事件将被激活。当 NavigationCacheMode为Enabled状态时,则会参考Frame类中CacheSize属性设置尺寸设置。例如:如果设置Frame 类CacheSize属性值为6,当第七个Page类页面载入时,第一个载入到缓存的Page类 页面将会从缓存中删除,而最新的Page类页面将会替代。 需要注意的是,当允许导航页面缓存时,位于内存中的导航页面具有完整的页面处理流程,也就是说,当前台页面重新刷新载入时,缓存中所有的页面Loaded事件都会同时执行,从而达到保存页面状态的目的,当用户需要访问上一级或下一级页面时,则会节省页面初始化事件,相对提高应用效率。 Silverlight导航框架Page类属于导航基础类之一,在随后的实例演示中,会经常用到其属性和方法,对于该类推荐认真学习。 今天暂时介绍到这里。下一篇将介绍Silverlight导航框架常用应用话题。 [Silverlight实例教程系列 - Silverlight Validation验证实例](http://silverlightchina.net/html/zhuantixilie/getstart/2010/0924/2035.html) [Silverlight实例教程系列 - Silverlight Out-of-Browser实例](http://silverlightchina.net/html/zhuantixilie/getstart/2010/0809/1709.html) [Silverlight实例教程系列 - Expression Blend实例中文教程](http://silverlightchina.net/html/zhuantixilie/getstart/2010/0409/978.html) 欢迎大家加入“专注Silverlight”QQ技术群,欢迎大家加入一起学习讨论Silverlight&WPF&Widnows Phone开发技术。  22308706(一群) 超级群500人  37891947(二群) 超级群500人  100844510(三群) 高级群200人  32679922(四群) 超级群500人  23413513(五群) 高级群200人  32679955(六群) 超级群500人  61267622(七群) 超级群500人  88585140(八群) 超级群500人  128043302(九群 企业应用开发推荐群) 高级群200人  101364438(十群) 超级群500人  68435160(十一群 企业应用开发推荐群)超级群500人
