Question

我在WPF应用程序中使用了DataTemplate -

<DataTemplate x:Key="mattersTemplate">
    <Border Name="border" BorderBrush="Aqua" BorderThickness="1" Padding="5" Margin="5">
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition/>
                <RowDefinition/>
                <RowDefinition/>
            </Grid.RowDefinitions>
            <Grid.ColumnDefinitions>
                <ColumnDefinition />
                <ColumnDefinition />
            </Grid.ColumnDefinitions>
            <TextBlock Grid.Row="0" Grid.Column="0" Text="FileRef:"/>
            <TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Path=FileRef}" />
            <TextBlock Grid.Row="1" Grid.Column="0" Text="Description:"/>
            <TextBlock Grid.Row="1" Grid.Column="1" Text="{Binding Path=Description}"/>
            <TextBlock Grid.Row="2" Grid.Column="0" Text="Priority:"/>
            <TextBlock Grid.Row="2" Grid.Column="1" Text="{Binding Path=Priority}"/>
        </Grid>
    </Border>
</DataTemplate>

然后我（在DocumentSetTemplateSelector类中）定义要使用的模板;

我想做/知道的是; 创建4个其他模板，这些模板将继承上述模板，然后允许覆盖某些属性;

一个例子（这个模板继承自上面的类） - 所以它们看起来一样;

<DataTemplate x:Key="documentSet_Accounting">
    <ContentPresenter Content="{Binding mattersTemplate}" 
         ContentTemplate="{StaticResource mattersTemplate}">
    </ContentPresenter>
</DataTemplate>

我希望有一个风格附加到这个（如果可能的话），以便获得这种效果;

<DataTemplate x:Key="documentSet_Accounting">
    <ContentPresenter fontsize="20" Content="{Binding mattersTemplate}" 
         ContentTemplate="{StaticResource mattersTemplate}">
    </ContentPresenter>
</DataTemplate>

或

<DataTemplate x:Key="documentSet_Accounting">
    <ContentPresenter Style="AccountingStyle" Content="{Binding mattersTemplate}" 
         ContentTemplate="{StaticResource mattersTemplate}">
    </ContentPresenter>
</DataTemplate>

如何在模板中使用样式继承而不是模板继承？

<Style x:Key="mattersTemplateStyle">
    <Setter Property="TextBlock.Foreground" Value="Green"/>
</Style>
<Style x:Key="documentSet_AccountingStyle" BasedOn="{StaticResource mattersTemplateStyle}">
    <Setter Property="TextBlock.FontSize" Value="20"/>            
</Style>
<DataTemplate x:Key="mattersTemplate">
    <Border Name="border" BorderBrush="Aqua" BorderThickness="1" Padding="5" Margin="5">
        <Grid Style="{StaticResource mattersTemplateStyle}">
            [...]
        </Grid>
    </Border>
</DataTemplate>
<DataTemplate x:Key="documentSet_Accounting">
    <Grid Style="{StaticResource documentSet_AccountingStyle}">
        <ContentPresenter Content="{Binding mattersTemplate}" ContentTemplate="{StaticResource mattersTemplate}"></ContentPresenter>
    </Grid>
</DataTemplate>

继承/ BasedOn datatemplate
