Problème de Menu

Bonjour à tous,

Je suis en train de créer un menu en ASP.Net, seulement voilà j'ai un petit problème.
Lorsque je navique dans le premier niveau pas de problème, lorsque je clique sur un élément j'arrive au deuxième niveau.

Par contre lorsque je clique sur un élément du deuxième niveau, il me reset ma page.

Quelqu'un aurait une idée ?

Voici mon code :
