c# wpf mouseevent opacity
As part of a diagram, I am drawing a few overlapping Shapes, each with Opacity=0.5, like here:
<Rectangle Fill="Blue" Opacity="0.5" MouseEnter="Rectangle_MouseEnter" />
<Rectangle Fill="Red" Opacity="0.5" />
private void Rectangle_MouseEnter(object sender, MouseEventArgs e)
When the user enters the shape with the mouse, some additional information should be displayed, but the event handler never gets called.
Is there a way to get MouseEnter events for all Shapes, instead of just the topmost one?
