récupérer l'id d'un noeud d'un treeview

bonjour,

je développe actuellement une application en asp.net et j'aimerais récupéré lors d'un clic droit l'id du noeud sur lequel j'ai cliqué du treeview que je génère dynamiquement en asp.net. Je m'y connais très peu en javascript et je n'ai pas la moindre idée de la façon qu'il faut que je m'y prenne...

Si quelqu'un pouvait me donner déjà une piste, ce serait très bien! Merci d'avance.

Code:

onclick="alert(thid.id)"

ok, mais le problème est qu'il n'existe pas d'attributs onclick sur un treeview asp.net.Et pour détecter le clic droit et déclencher le msgbox c'est :

Code:

document.oncontextmenu=alert(this.id)

??

iml genère quel code html ton treeview asp ?

en fait je viens de me rendre compte que le this.id me renvoie l'id du treeview et non du noeud sur lequel je clique!

mais quand je reste sur un noeud, je vois en bas de la page la fonction javascript suivante :

Code:

javascript:__doPostBack('montreeview',s-1\\IDduNoeud)

peut-on récupérer d'une certaine manière l'id qui est dans cette fonction??

sinon, voici ce qu'il génère comme code pour l'apparence du treeview tel que je le vois :

bah je peux pas le rajouter puisque c'est le code html qui se génère automatiquement quand je lance mon appli...

dsl si je suis un cas désespéré... :roll:
en tout cas, je te remercie quand même que tu m'aides!
