问题描述
我有一个Viewbox:
I have a Viewbox:
<Viewbox x:Key="SampleViewbox" >
<Grid>
<Ellipse Stroke="#e2e2e0" StrokeThickness="6" Fill="#d5273e" Width="128" Height="128"/>
</Grid>
</Viewbox>
然后我将其包括在样式中:
I then include this in a Style like:
<Style x:Key="SampleStyle" TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="Transparent" >
<ContentPresenter Content="{StaticResource SampleViewbox}"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
现在我用 SampleStyle
<Grid>
<StackPanel>
<Button Style="{StaticResource SampleStyle}" Height="50" Width="50"></Button>
<Button Style="{StaticResource SampleStyle}" Height="80" Width="80"></Button>
<Button Style="{StaticResource SampleStyle}" Height="20" Width="20"></Button>
</StackPanel>
</Grid>
但是,只有一个按钮具有椭圆(视图框)
However, Only one button has the Ellipse (viewbox)
如何使所有按钮具有/显示椭圆形?
How can I make all the buttons have/show the ellipse??
推荐答案
Viewbox是FrameworkElement,不能属于多个父级。每次按钮请求资源 {StaticResource SampleViewbox}
时,它们都会获得相同的实例。
Viewbox is FrameworkElement which cannot belong to multiple parents. Every time buttons request a resource {StaticResource SampleViewbox}
they get the same instance.
要更改该行为,请添加 x:Shared = False
属性
to change that behavior add x:Shared="False"
attribute
<Viewbox x:Key="SampleViewbox" x:Shared="False">
