WPF – Loaded event in browser applications

This is a slightly strange one to my thinking.

If you have a loaded event in a panel on a page, it will get fired multiple times.
This goes against the behaviour of a WPF application (or Winforms for that matter).
I don’t know if the same is true for an Asp.Net forms application, since I haven’t done many.

It seems to be using the Loaded event as more of an Activated event.

To see this behaviour easily:

1. Create a WPF browser application (xbap)
2. Add a tab control
3. Add a panel to 1 tab
4. Add another panel to another tab
5. do something in Loaded event in first tab , eg change colour of the panel

When you click on second tab and back to first tab, the loaded event will be fired again
