Wpf 使用画布作为具有可绑定颜色的图标
对于许多Wpf 使用画布作为具有可绑定颜色的图标,wpf,wpf-controls,resourcedictionary,wpf-4.0,visualbrush,Wpf,Wpf Controls,Resourcedictionary,Wpf 4.0,Visualbrush,对于许多WPFer，我使用此模式创建向量图标： 1-定义画布包含以下数据： 资源项目： 现在，如您所见，我必须在画布中获取路径，a填充值： <Path Fill="#FFFFFF00"> 我试着像下面那样使用它： <Path Fill="{Binding ui:UIElement.VisualIconForeground,RelativeSource={RelativeSource TemplatedParent}}"> 但它不起作用。你知道怎么做吗？我的意思是绑
WPF画布画布中获取路径
，a填充
值：
<Path Fill="#FFFFFF00">
我试着像下面那样使用它：
<Path Fill="{Binding ui:UIElement.VisualIconForeground,RelativeSource={RelativeSource TemplatedParent}}">
但它不起作用。你知道怎么做吗？我的意思是绑定资源项的某个属性以设置它们将在何处使用-糟糕的英语，我知道，对不起：（评论太长了，所以我会在这里写：
如果我理解正确，SubmitVisualIcon
是一个资源
。资源绑定
不支持，因此您不使用模板parent
进行绑定
，因为资源
不是可视化树的一部分，也不是模板的一部分。您可能需要寻找替代方法
或者，您可以使用应用程序支持的设置。在设置中设置颜色，并在资源中引用它，如下所示：
xmlns:properties="clr-namespace:MyNamespace.Properties"
<Path Fill="{Binding Source={x:Static properties:Settings.Default}, Path=SomeColor, Mode=TwoWay}" ... />
xmlns:properties=“clr namespace:MyNamespace.properties”
可以找到更多信息。最后，我找到了一个在这种情况下有效的解决方案。我应该使用Rectangle.OpacityMask
而不是Rectangle.Fill
：

因此，对于VisualIcon
来说，绑定效果很好，您想对VisualIcon前台
做同样的事情吗？是的，没错。我想Canvas.Path
从ControlTemplate
读取Fill
属性，如果我理解正确，SubmitVisualIcon
是一个资源。资源 绑定
不支持，因此您不能使用TemplatedParent
进行绑定
，因为资源不是可视化树的一部分，也不是模板的一部分。可能您必须寻找替代方法。+1请注意。但这不是答案，我希望能够更改路径。填充
属性在任何地方都可以使用。但是谢谢你的努力。干杯
