Nikakor ne morm pogruntat kako routed eventi delujejo, še posebej na primeru, ko imaš nek stack panel in na njega šopaš user controle z nekimi informacijami in gumbom in ko pritisneš na ta gumb, se bi morale te informacije oziroma ta objekt (recimo) shranit v listo.
Se pravi kontrola:
To je pa še main window
Upam da je kolk tolk jasno kaj bi rad, sem pa pregledal že večino linkov na temo routed eventov, ampak nekako ne morem razvozlat zadeve :)
