Les regles du Binding en XAML [Fait]

**Schiele** · 05/02/2009, 09h45

Bonjour a toutes et a tous,

une nouvelle question : comment peut on lier par binding (uniquement sous blend, donc XAML accepté!) , la valeur situé dans un style, lors d'un evenement catché dans un template? (Style et Template ne se trouvant pas sur le meme objet)

Si vous avez de bons tutos sur le binding (tous nieaux) je suis preneur aussi!

Merci de votre attention.

Mon probleme vient des triggers...

Salut,

En effet, c'est surement au niveau des EventTrigger que ça doit planter... Si tu pouvais en dire davantage sur l'erreur qui est donnée.
Je ne pense pas que faire {StaticResource STopen} alors que STopen est dans un Style soit réalisable...

Après, j'aurai plus mis "ToggleButton.Checked" que "MonBtn.Checked" (pareil pour unchecked)... Mais ça ne doit pas résoudre le problème.
