Silverlight Toolkit - DragDrop StackedColumnSeries Chart

Question

I have a Stacked Column Chart from the Silverlight Toolkit from April 2011.

I wish to select and drag one layer from a stack into a regular column chart for details.

Is this possible? I can handle all logic in code but I need the sweet semi transperant adorner...

Answer 1

Sounds like a fun challenge. Silverlight does not have an adorner layer. The best way to achieve this sort of effect is to use a Popup . These live outside of the visual tree, allowing you to use them to place content over your current visuals. You can create a full-screen Popup , then grab a copy of the series you want to drag (perhaps using a WriteableBitmap ).

See for example this blog post which animates an element by copying it into a Popup :
