我的项目中有一个Resources.xaml文件,其中包含一个资源字典,如下所示:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style x:Key="GPHeaderFontSize" TargetType="TextBlock">
<Setter Property="FontWeight" Value="Bold" />
<Setter Property="FontSize" Value="24" />
<Setter Property="Text" Value="BLAHHHHH"/>
</Style>
</ResourceDictionary>
我在App.xaml中包含了这个字典,如下所示:
<Application x:Class="GoldenPlains.App"
xmlns="schemas.microsoft.com/winfx/2006/xaml/presentation";
xmlns:x="schemas.microsoft.com/winfx/2006/xaml";
xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone">
<Application.Resources>
<local:LocalizedStrings xmlns:local="clr-namespace:GoldenPlains" x:Key="LocalizedStrings"/>
<ResourceDictionary x:Key="GPResources">
<ResourceDictionary.MergedDictionaries>
<!-- Sometimes VS2012 complaining about path with blue line, please ignore it as path is correct -->
<ResourceDictionary Source="Styles/GPResources.xaml"/>
</ResourceDictionary.MergedDictionaries>
<Style x:Key="GPRootOverlayBarStyle" TargetType="Image">
<Setter Property="Source" Value="Assets/Images/root_brown_horizontal_bar.png"/>
<Setter Property="Width" Value="729"/>
<Setter Property="HorizontalAlignment" Value="Left"/>
<Setter Property="Stretch" Value="Uniform"/>
</style>
</Application.Resources>
...
...
</Application>
但是,当我尝试从另一个Page.xaml文件引用资源字典中的元素时,它似乎无法解析资源….
例如:
我试过使用像这样的绑定:
<TextBlock Style="{Binding Path=LocalizedResources.MyTextBlockStyle, Source= {StaticResource GPResources}}"/>
它并不表示出现问题,但UI上没有显示任何内容.
正确方向上的一点很棒,欢呼声.
最佳答案 App.xaml中的资源字典定义应该类似于以下示例:
<Application.Resources>
<ResourceDictionary>
<local:LocalizedStrings xmlns:local="clr-namespace:GoldenPlains" x:Key="LocalizedStrings"/>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Styles/GPResources.xaml"/>
</ResourceDictionary.MergedDictionaries>
<!-- Other resources if you have -->
</ResourceDictionary>
</Application.Resources>
然后,当您需要将Resources.xaml中定义的样式应用于UI控件时,只需引用样式的键/名称:
<TextBlock Style="{StaticResource GPHeaderFontSize}" />
注意:所有资源都需要在ResourceDictionary标记内,包括LocalizedStrings.
