WPF Datagrid与单元格中的Viewbox鼠标右键选择(WPF Datagrid with a Viewbox in a cell block right mouse button selection)

我使用带有模板化单元格的数据网格来显示我的数据。 我可以添加我想到的任何类型的UI元素（DataTemplate，ContentControl，StackPanel，Rectangle），一切都还可以。 但是只要我添加一个ViewBox，右键单击鼠标按钮（在元素上）就会停止选择行/单元格。 左键单击继续正常工作。

据我所知，ViewBox应该只是可视化的，但不会影响任何事件路由。

重现问题的示例代码（红色矩形工作，绿色不工作）：

<DataGrid ItemsSource="{Binding}" IsReadOnly="True" AutoGenerateColumns="False"> <DataGrid.Columns> <DataGridTemplateColumn> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <StackPanel Orientation="Horizontal" Margin="10"> <Rectangle Width="50" Height="50" Fill="Red" /> <Viewbox> <Rectangle Width="50" Height="50" Fill="Green" /> </Viewbox> </StackPanel> </DataTemplate> </DataGridTemplateColumn.CellTemplate> </DataGridTemplateColumn> </DataGrid.Columns> </DataGrid>

我尝试在子控件中捕获鼠标事件并将其发送给父级但没有成功。

I use a datagrid with templated cells to present my data. I can add any type of UI element I think of (DataTemplate, ContentControl, StackPanel, Rectangle) and everything still work fine. But as soon as I add a ViewBox, the right click mouse button (on the element) stop selecting the row/cell. Left click keep working properly.

As far as I know, a ViewBox is supposed to be visual only, but not to influence any event routing.

Sample code reproducing the problem (red rectangle works, green don't):

<DataGrid ItemsSource="{Binding}" IsReadOnly="True" AutoGenerateColumns="False"> <DataGrid.Columns> <DataGridTemplateColumn> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <StackPanel Orientation="Horizontal" Margin="10"> <Rectangle Width="50" Height="50" Fill="Red" /> <Viewbox> <Rectangle Width="50" Height="50" Fill="Green" /> </Viewbox> </StackPanel> </DataTemplate> </DataGridTemplateColumn.CellTemplate> </DataGridTemplateColumn> </DataGrid.Columns> </DataGrid>

I tried capturing the mouse event in the child control and send it to the parent but without success.
