c# - How to save entire Scrollable canvas as Png -

I have a canvas class that enforces VirtualizingPanel and IScrollInfo This class is contained within a ScrollViewer. I have the content of the whole canvas class How can I save as PNG only?

I know how to save PNG, the problem is simply the easiest way to catch special control. When the control is out of the scene, it is cut off

I do not think you are virtualizing Do this with the panel because its entire goal in life is to keep the number of children, in which it is a complete minimum.

What you want to do is create a non-virtualization version in the code for your PNG generation.
