Question

Here is a problem: after loading some visual elements, I need to change something knowing their new sizes. There is MeasureOverride method, but it is called before changing the size. Is there any method that is called after it?

P.S. I know that I can calculate new sizes having old ones, but new sizes aren’t calculated simply. It would be much easier to just use such an event (if it exists).

Answer 1

Are you looking for the FrameworkElement.SizeChanged event?

MSDN’s description:

Occurs when either the ActualHeight or the ActualWidth properties change value on a FrameworkElement.

EDIT:

This article has a good description of both the SizeChanged and LayoutUpdated events, including an overview of how the layout loop works.
