全球风格不起作用

我在MainWindow.Resources中定义了以下样式:

<Style TargetType="{x:Type ComboBox}">
    <Setter Property="Height" Value="26"/>
    <Setter Property="ItemTemplate">
        <Setter.Value>
            <DataTemplate>
                <TextBlock Text="{Binding}"/>
            </DataTemplate>
        </Setter.Value>
    </Setter>
    <Setter Property="VerticalContentAlignment" Value="Center"/>
    <Setter Property="Width" Value="358"/>
</Style>
<Style TargetType="{x:Type TextBlock}">
    <Setter Property="MaxWidth" Value="350"/>
    <Setter Property="TextTrimming" Value="CharacterEllipsis"/>
    <Setter Property="VerticalAlignment" Value="Center"/>
</Style>

TextBlock样式适用于在我的MainWindow中定义的TextBlock元素,但它不适用于我的ComboBoxes用作DataTemplate的TextBlock。为什么呢?

如果我在元素本身内设置TextBlock属性,一切正常:

<Style TargetType="{x:Type ComboBox}">
    <Setter Property="Height" Value="26"/>
    <Setter Property="ItemTemplate">
        <Setter.Value>
            <DataTemplate>
                <TextBlock MaxWidth="350" Text="{Binding}" TextTrimming="CharacterEllipsis" VerticalAlignment="Center"/>
            </DataTemplate>
        </Setter.Value>
    </Setter>
    <Setter Property="VerticalContentAlignment" Value="Center"/>
    <Setter Property="Width" Value="358"/>
</Style>

模板具有不同的排序范围,您可以将样式移动到Application.Resources,即使在整个应用程序的数据和控件模板中也适用。{/ p>

使用动态资源

 <DataTemplate DataType="{x:Type local:DataSource}">
     <TextBox Style="{DynamicResource TextBoxStyle}" Text="{Binding}"  />
</DataTemplate>

<ComboBox>
     <ComboBox.Resources>
             <Style x:Key="TextBoxStyle" BasedOn="{StaticResource {x:Type ListBoxItem}}" TargetType="TextBox">
        </Style>
    </ComboBox.Resources>
</ComboBox>
