[WPF] Problème de menu dans fenetre transparente

**Zucher** · 29/01/2008, 10h34

Bonjour,

J'utilise un Menu dans une fenetre ayant le flag AllowsTransparency activé. Le probleme est que le popup associé au MenuItem apparait en arrière plan.

Comment faire pour forcer un popup à apparaitre au premier plan, pour contourner un pb qui viendrait de .NET 3.0

Merci

Zucher

En changeant le ZIndex ?

**Zucher** · 30/01/2008, 09h10

Le Zindex n'est disponible que sur le submenuborder, mais pas sur le Popup lui même. une modification du zindex sur le Border n'a pas d'effet.

ce qui est le plus étonnant, c'est que sur certaines machines le popup est au premier plan et que sur d'autre il y a le problème.

**Zucher** · 30/01/2008, 22h28

J'ai trouvé une alternative, en utilisant le flag Topmost sur la fenetre principale, ce qui ne me gene pas dans mon cas car je souhaite realiser un toaster dans ke systray, par contre cela devient un reel souci dans les autres cas

Merci
