我有一个扩展器,它的标题旋转 -90 度:
<Expander Name="exProduct" Grid.Column="1" ExpandDirection="Left"
HorizontalAlignment="Right" VerticalAlignment="Stretch">
<Expander.Header>
<TextBlock Text="Add Product" FontSize="18"
<TextBlock.LayoutTransform>
<RotateTransform Angle="-90"/>
</TextBlock.LayoutTransform>
</TextBlock>
</Expander.Header>
我怎样才能使用这样的东西,并且标题旋转 -90 度:
<Window.Resources>
<Style x:Key="ExpanderEx" TargetType="Expander">
<Setter Property="Header" Value="Show"/>
<Style.Triggers>
<Trigger Property="IsExpanded" Value="True">
<Setter Property="Header" Value="Hide"/>
</Trigger>
</Style.Triggers>
</Style>
</Window.Resources>
<Expander Style="{StaticResource ExpanderEx}" >
<StackPanel>
<Button Width="100" Height="50"/>
</StackPanel>
</Expander>
