希望将导航框架放置在整个应用程序中可用的位置

xaml silverlight

Cyberherbalist · 技术社区 · 14 年前

我的Silverlight应用程序中有相当于菜单页的内容。它在StackPanel中有一些超链接按钮。使用带有UriMapper的导航框架将超链接映射到应用程序中的其他页面uri。所有这些都显示在菜单页的LayoutRoot网格中。我希望整个应用程序都可以使用UriMapping,这意味着它应该在App.xaml中,但是我不知道如何将它放在那里,所以它可以工作。有什么想法吗?下面是一些与我得到的代码类似的代码:

<Grid x:Name="LayoutRoot">
    <Border x:Name="ContentBorder" Style="{StaticResource ContentBorderStyle}">
        <navigation:Frame x:Name="ContentFrame" Style="{StaticResource ContentFrameStyle}" Source="" Navigated="ContentFrame_Navigated" NavigationFailed="ContentFrame_NavigationFailed">
             <navigation:Frame.UriMapper>
                 <uriMapper:UriMapper>
                     <uriMapper:UriMapping Uri="/AgencyTechnical" MappedUri="/Views/AgencyTechnical.xaml"/>
                     <uriMapper:UriMapping Uri="/AgencyBusiness" MappedUri="/Views/AgencyBusiness.xaml"/>
            ...
                 </uriMapper:UriMapper>
             </navigation:Frame.UriMapper>
         </navigation:Frame>
     </Border>

     <ScrollViewer x:Name="PageScrollViewer" Style="{StaticResource PageScrollViewerStyle}" Margin="10,10,0,0" Width="640">
         <StackPanel Name="stackPanel1" Width="490" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="10,10,0,0" Height="326">
             <TextBlock Text="Agency Screens" Name="AgencyScreenLabel" Style="{StaticResource MenuLabelStyle}" />
                <HyperlinkButton Name="AgencyTechInfoLink" Style="{StaticResource LinksMenuStyle}"
                    Content="Agency Technical Information" ... />
                <HyperlinkButton Name="AgencyTechInfoLink" Style="{StaticResource LinksMenuStyle}"
                    Content="Agency Technical Information" ... />

我接受了加布里埃尔·麦克亚当斯的回答,但我得稍微修改一下。我正在使用Silverlight导航页的模板,App.xaml中有一个资源字典,如果直接将映射添加到Application.Resource s节点中,就会干扰它。我发现我可以将映射添加到Styles.xaml中,它工作得很好。我得到一个“类型'ResourceDictionary'在ResourceDictionary中,没有密钥。”如果执行以下操作,则会出错:

<Application.Resources>

   <... Uri mapping here />

   <ResourceDictionary>
      <ResourceDictionary.MergedDictionaries>
         <ResourceDictionary Source="Assets/Styles.xaml"/>
      </ResourceDictionary.MergedDictionaries>
   </ResourceDictionary>

</Application.Resources>

但是将它添加到Assets/Styles.xaml中效果很好。

您可以将其放入应用程序资源中,如下所示:

<Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    x:Class="YourSilverlightApplication.App"
    xmlns:nav="clr-namespace:System.Windows.Navigation;assembly=System.Windows.Controls.Navigation"
>
    <Application.Resources>
        <nav:UriMapper x:Key="uriMapper">
            <nav:UriMapping Uri="/AgencyTechnical" MappedUri="/Views/AgencyTechnical.xaml"/>
            <nav:UriMapping Uri="/AgencyBusiness" MappedUri="/Views/AgencyBusiness.xaml"/>
        </nav:UriMapper>
    </Application.Resources>
</Application>

这是您的页面(已修改):

<Grid x:Name="LayoutRoot">
    <Border x:Name="ContentBorder" Style="{StaticResource ContentBorderStyle}">
        <navigation:Frame x:Name="ContentFrame" Style="{StaticResource ContentFrameStyle}" Source="" Navigated="ContentFrame_Navigated" NavigationFailed="ContentFrame_NavigationFailed" navigation:Frame.UriMapper="{StaticResource uriMapper}">
        </navigation:Frame>
     </Border>

     <ScrollViewer x:Name="PageScrollViewer" Style="{StaticResource PageScrollViewerStyle}" Margin="10,10,0,0" Width="640">
         <StackPanel Name="stackPanel1" Width="490" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="10,10,0,0" Height="326">
             <TextBlock Text="Agency Screens" Name="AgencyScreenLabel" Style="{StaticResource MenuLabelStyle}" />
                <HyperlinkButton Name="AgencyTechInfoLink" Style="{StaticResource LinksMenuStyle}"
                    Content="Agency Technical Information" ... />
                <HyperlinkButton Name="AgencyTechInfoLink" Style="{StaticResource LinksMenuStyle}"
                    Content="Agency Technical Information" ... />
