用于类型“CardViewItem”的样式不能应用于类型“ContentPresenter”。

Question

    <Style x:Key="{x:Type local:CardViewItem}" TargetType="{x:Type local:CardViewItem}">
        <Setter Property="BorderThickness" Value="1"/>
        <Setter Property="BorderBrush" Value="Black"/>
        <Setter Property="Margin" Value="2"/>
        <Setter Property="Background" Value="Red"/>        
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type local:CardViewItem}">
                    <Border Background="{TemplateBinding Background}"
                            BorderBrush="{TemplateBinding BorderBrush}"
                            BorderThickness="{TemplateBinding BorderThickness}"
                            Padding="{TemplateBinding Padding}"
                            SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
                            Margin="{TemplateBinding Margin}">
                        <Grid>
                            <Grid.RowDefinitions>

                            <Button Grid.Row="0" Content="Full View" Height="24"/>
                            <ContentPresenter Grid.Row="1" Content="{TemplateBinding Content}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                        </Grid>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

    <Style x:Key="{x:Type local:CardView}" TargetType="{x:Type local:CardView}">
        <Setter Property="ItemsPanel">
            <Setter.Value>
                <ItemsPanelTemplate>
                    <WrapPanel IsItemsHost="True"/>
                </ItemsPanelTemplate>                
            </Setter.Value>

                <ControlTemplate TargetType="{x:Type local:CardView}">
                    <Border Background="{TemplateBinding Background}"
                            BorderBrush="{TemplateBinding BorderBrush}"
                            BorderThickness="{TemplateBinding BorderThickness}">
                        <ScrollViewer HorizontalScrollBarVisibility="{TemplateBinding ScrollViewer.HorizontalScrollBarVisibility}">
                            <Grid>
                                <ContentPresenter x:Name="PART_SelectedItemContentHost" Content="{TemplateBinding SelectedItem}" Visibility="Collapsed"/>
                                <ItemsPresenter x:Name="PART_AllItemsContentHost"/>
                            </Grid>
                        </ScrollViewer>
                    </Border>
                	<ControlTemplate.Triggers>
                		<Trigger Property="CardMode" Value="False">
                			<Setter Property="Panel.ZIndex" TargetName="PART_SelectedItemContentHost" Value="1"/>
                			<Setter Property="Visibility" TargetName="PART_SelectedItemContentHost" Value="Visible"/>
                			<Setter Property="Visibility" TargetName="PART_AllItemsContentHost" Value="Collapsed"/>
                		</Trigger>
                	</ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>

    </Style>

当在CardView的style中加入

        <Setter Property="ItemContainerStyle" Value="{DynamicResource {x:Type local:CardViewItem}}"/>

程序运行出错,"用于类型“CardViewItem”的样式不能应用于类型“ContentPresenter”。" 为什么?

后台代码如下:

//CardViewItem.cs
    public class CardViewItem : ContentControl
    {
        static CardViewItem()
        {
            DefaultStyleKeyProperty.OverrideMetadata(typeof(CardViewItem), new FrameworkPropertyMetadata(typeof(CardViewItem)));
        }
    }


//CardView.cs
    [StyleTypedProperty(Property = "ItemContainerStyle", StyleTargetType = typeof(CardViewItem))]
    public class CardView : Selector
    {...}
