There's more to virtualizing an ItemsControl than just setting VirtualizingStackPanel.IsVirtualizing. See this question for more details Basically your ItemsControl. Template needs a ScrollViewer to enable Virtualization.

I suspect that once you get your ItemsControl is virtualizing correctly, you'll see a dramatic improvement in performance. Virtualization means that only the visible items are rendered. When you scroll, the UI containers get re-used and just the DataContext behind them changes.

This means that instead of drawing 2000 records, you would only be drawing about 20 (or however many are visible).

Doing the same without the viewbox and the bindings to ActualWidth and ActualHeight will help a lot, if it is feasible to replace with an lighter alternative.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
