Allow mouse events to pass through semitransparent Popup
问题 I'm trying to do a drag-n-drop operation from a control inside a Popup . The content being dragged will be placed at the position of the drop so when the drag starts I want to make the Popup semitransparent to allow placement under it. But so far I fail to make mouse events pass through my semitransparent Popup . The following xaml works fine, the Button is still clickable when hovering the Rectangle with the mouse <Grid> <Rectangle Panel.ZIndex="2" Width="200" Height="200" Fill="Green"
