棱镜4 / Silverlight 4 / MEF - 未找到区域

标签: silverlight prism

我只是在学习PRISM所以可能这是一个非常简单的错误:我试图在'Style'中定义Region并且找不到它们:( :(

在主'Shell'窗口中,我有'ContentControl',其中包含'Frame'对象。 'ContentControl'在附加的ResourceDictionary中设置样式,并在那里定义了所有区域(带有其他颜色,画笔,按钮,网格等等)但是无论何时程序运行(所有正确显示在屏幕上),IRegionManager.Regions都是空集合......

我可以做些什么来使用'Style'中的区域???

这是代码:

Shell.xaml

<UserControl x:Class="CardManagment.Shell"
             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:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk"
             d:DesignHeight="300"
             d:DesignWidth="400"
             mc:Ignorable="d">
    <ContentControl HorizontalAlignment="Stretch"
                    VerticalAlignment="Stretch"
                    Style="{StaticResource MainWindowStyle}">
        <sdk:Frame x:Name="MainFrame"
                   HorizontalAlignment="Stretch"
                   VerticalAlignment="Stretch"
                   BorderBrush="#FFFB0000"
                   Style="{StaticResource GlobalNavigationFrameStyle}"
                   UriMapper="{StaticResource GlobalUriMapper}" />
    </ContentControl>
</UserControl>

和ResourceDictionary:

     <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        xmlns:prism="clr-namespace:Microsoft.Practices.Prism.Regions;assembly=Microsoft.Practices.Prism" 
        xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk" xmlns:toolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit">
            <Style x:Key="MainWindowStyle" TargetType="ContentControl">
                <Setter Property="Foreground" Value="#FF000000"/>
                <Setter Property="HorizontalContentAlignment" Value="Left"/>
                <Setter Property="VerticalContentAlignment" Value="Top"/>
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="ContentControl">
    ...
    ...
    ...
    <Border Grid.Row="1" BorderThickness="2" CornerRadius="2" BorderBrush="#FFDC1EBA">
        <ContentControl x:Name="GlobalLogoRegion" prism:RegionManager.RegionName="GlobalLogoRegion" />
    </Border>
...
...

好的 - 现在我在此页面找到了答案:Regions inside DataTemplates in Prism v4 using a region behavior

实际上,根据这篇文章,它是PRISM中的一个已知错误。
