Le tabcontainer n'apparait pas

Salut je suis debutant
En fait j'ai ajouter un controle TabContainer, en local ca fonctionne parfaitement
j'ai bien mes onglets  

mais sur mon site ca ne marche le TabContainer n'apparait pas
j'ai une erreur 'sys' non defini
mais la pages apparait sans le tab
je pense qu'il doit me manquer une dll ou autre chose
que puis je faire ?

bonjour,
il te manque des rubriques dans le web.config (<httpHandlers> entre autres)
Compare le tien avec celui d'un projet qui fonctionne : ajaxControltoolKit par ex.
@+Gilles

en tous cas merci d'avoir repondu
j'ai fais comme tu m'as dit

j'ai comparré avec le web.config du repertoire C:\Program Files\Microsoft ASP.NET\AJAX Control Toolkit\SampleWebSite

mais ca marche toujour pas
je te copi mon web config car je cherche depuis quelques jours  et j'ai vraiment envi de me couper les veines

Lol
merci pour ton aide
