Is there a “All Children loaded” event in WPF

Question

I am listening for the loaded event of a Page. That event fires first and then all the children fire their load event. I need an event that fires when ALL the children have

Answer 1

WPF cant provide that kind of an event since most of the time Data is determining whther to load a particular child to the VisualTree or not (for example UI elements inside a DataTemplate)

So if you can explain your scenario little more clearly we can find a solution specific to that.
