How to save entire Scrollable canvas as Png

Question

I have a Canvas class that implements VirtualizingPanel and IScrollInfo. This class is contained inside a ScrollViewer. How can I save the contents of the entire Canvas class only as Png?

I know how to save as Png, problem is what is the easiest way to grab only the particular control. When the control is out of view, it gets clipped

Answer 1

I don't think you will be able to do this with a virtualizing panel as its whole goal in life is to keep the number of children it contains to an absolute minimum.

What you might want to do is create a non-virtualizing version in code and use that for your png generation.
