我编写了一个简单的 Silverlight 应用程序。我的样式在设计时正确显示,但是当我尝试运行应用程序时,资源字典文件中合并到 app.xaml 文件中的任何样式在运行时都不会应用于任何控件。
实际上,UserControl
似乎只有样式不适用。但其余的都在工作(如Button
页面上的)。什么可能导致此问题,我该如何解决?
我的代码是这样的:
样式.xaml:
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style TargetType="UserControl">
<Setter Property="FlowDirection" Value="RightToLeft" />
<Setter Property="FontFamily" Value="Tahoma" />
<Setter Property="Background" Value="Aqua" />
</Style>
<Style TargetType="Button" >
<Setter Property="Background" Value="Aqua" />
</Style>
</ResourceDictionary>
应用程序.xaml:
<Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="Silverlight.Test._01.App"
>
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Styles.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
MainPage.xaml:
<UserControl x:Class="Silverlight.Test._01.MainPage"
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"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="400" xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk">
<Grid x:Name="LayoutRoot" Background="White">
<Button Content="This is a test" Height="23" HorizontalAlignment="Left" Margin="12,12,0,0" Name="button1" VerticalAlignment="Top" Width="220" />
<sdk:Label Height="28" HorizontalAlignment="Left" Margin="12,6,0,0" Name="label1" VerticalAlignment="Top" Width="351" Content="Test label" />
</Grid>
</UserControl>
