MouseCapture prevents all mouse based triggers from firing in WPF

I am using CaptureMouse() during a drag and drop operation to make sure I don't miss the MouseUp event, but this seems to prevent any mouse events reaching any other objects on my Canvas. This means that my IsMouseOver based triggers don't work, but I need them to indicate valid locations where the object can be dropped.

Am I doing this wrong, or is there a way of making sure everything on my Canvas still gets mouse events?

Are the elements part of the SubTree of your canvas? or outside of the canvas? If they are within then you could probably use the Capture method that takes a CaptureMode.

Mouse.Capture(elementToCapture, CaptureMode.SubTree);

Alternatively, you should look at the DragDrop class and consider using the Drop event instead?
