Question

<Button 
    Grid.Column="0"
    Width="18" 
    Height="18"  
    Margin="0,0,5,0"
    Template="{StaticResource EditSvg}">
            
     <StackPanel Orientation="Horizontal" VerticalAlignment="Center" HorizontalAlignment="Center">
         <ContentControl Template="{StaticResource EditSvg}"/>
     </StackPanel>
</Button>

我如何能够将刷子动态绑定到中风属性？ 我能够做这样的事情：

<ControlTemplate x:Key="DeleteSvg">
    <Viewbox Stretch="Uniform">
        <Canvas Width="14"
                Height="16">
            <Path Data="M1.1889 4.2485H13.1889M5.6889 7.24971V11.7515M8.6889 7.24971V11.7515M1.9389 4.2485L2.6889 13.2521C2.6889 13.6501 2.84694 14.0318 3.12824 14.3132C3.40955 14.5946 3.79108 14.7527 4.1889 14.7527H10.1889C10.5867 14.7527 10.9683 14.5946 11.2496 14.3132C11.5309 14.0318 11.6889 13.6501 11.6889 13.2521L12.4389 4.2485M4.9389 4.2485V1.99759C4.9389 1.79859 5.01792 1.60775 5.15857 1.46704C5.29923 1.32633 5.48999 1.24728 5.6889 1.24728H8.6889C8.88782 1.24728 9.07858 1.32633 9.21923 1.46704C9.35989 1.60775 9.4389 1.79859 9.4389 1.99759V4.2485"
                  Fill="#00000000"
                  Stroke="{Binding Path=Tag, RelativeSource={RelativeSource AncestorType=Control}}"
                  StrokeEndLineCap="round"
                  StrokeLineJoin="round"
                  StrokeStartLineCap="round" />
        </Canvas>
    </Viewbox>
</ControlTemplate>

并在我的父控件上设置标签。尽管工作了，但感觉不到。有更好的方法吗？

以从ControlTemplate中的内部绑定到父属性

Stroke="{Binding Tag, RelativeSource={RelativeSource Mode=TemplatedParent}}"

或这个

Stroke="{Binding Tag, RelativeSource={RelativeSource AncestorType=Control, Mode=FindAncestor}}"

ControlTemplate上的目标类型期望某些控件应用模板不会按需要行为。
