Question

我只能在按钮元素上看到路径：

<ComboBox
    Margin="0 0 0 0"
    ItemsSource="{Binding Path=SearchTypes}"
    SelectedItem="{Binding Path=SearchType}">
    <ComboBox.ItemTemplate>
        <DataTemplate>
             <Button>
                 <Path
                    Stretch="Uniform"
                    HorizontalAlignment="Center"
                    VerticalAlignment="Center"
                    Data="{Binding Converter={StaticResource searchtypetoimagepathconverter}}" />
             </Button>
         </DataTemplate>
    </ComboBox.ItemTemplate>
</ComboBox>

修改我的转换器看起来像这样：

 public class SearchTypeToImagePathConverter : IValueConverter
 {
     public object Convert(object value, Type targetType, object parameter,
         System.Globalization.CultureInfo culture)
     {
         if ((SearchType)value == SearchType.Customers)
             return App.Current.Resources["Geometry.User"];
         else
             return App.Current.Resources["Geometry.Share"];

     }

     public object ConvertBack(object value, Type targetType, object parameter,
         System.Globalization.CultureInfo culture)
     {
         return value.Equals(true) ? parameter : Binding.DoNothing;
     }
 }

以下xaml也有效：

<ComboBox Grid.Column="0">
    <ComboBoxItem Name="share">                                  
      <Path Stretch="Uniform"
         Margin="0 0 0 0"
         VerticalAlignment="Center"
         Fill="{TemplateBinding Foreground}"
         Data="{StaticResource Geometry.Share}" />
    </ComboBoxItem>
    <ComboBoxItem Name="user">                        
       <Path Stretch="Uniform"                       
         Margin="0 0 0 0"
         VerticalAlignment="Center"
         Fill="{TemplateBinding Foreground}"
         Data="{StaticResource Geometry.User}" />
    </ComboBoxItem>
</ComboBox>

因此转换器的结果是返回StreamGeometry，它只显示在Button内的Path.Data中。我不知道这意味着什么。

path-element的正确父级是什么？

Answer 1

使用xaml图标的流行方法如下所示。所以回答你问题Path的父亲可能是一个VisualBrush。

这表明了两种方式。用作不透明蒙版或用作填充。这可以应用于任何用于创建图标效果的控件。

这是您的确切用例。如果这有助于他人的利益，请将其标记为答案。

Answer 2

编辑你应该添加到Path元素：Stroke =＆＃34; Red＆＃34;并删除按钮。

Answer 3

我同意评论说，Path对象不需要父母，但为了解决您的问题，这可能有所帮助：Button是ContentControl，增加了功能。您不需要添加的功能，因此请尝试将Path包裹在ContentControl。

中

Answer 4

Button具有默认样式，因此它提供了Stroke和Fill，使Button.Path.Data中指定的StreamGeometry可见。

然而，ContentControl或普通Path元素以某种方式获取这些不可见的值，因此它们不会显示。

这是不好的答案，但我已经多次编辑了这个问题，我在这里写了答案。请用合适的参考资料和数据做出更好的答案，我接受它。
