wpf

I use the Panel to provide custom layout of UIElements.
For this, I override MeasureOverride and ArrangeOverride. In ArrangeOverride proper locations are given to Children.

In my application, there is a bunch of rather heavy (by number of visuals) children inside the panel, but only 2 of them are located inside the visible region at a time.

Working with my application I feel like all the visuals are drown.

I need to introduce a kind of 'virtualization' and make the children render (or take CPU cycles) selectively.

How do I?
