Hi,
Did you get any javascript error? Because there are probably other conflicts between those two dynamic libraries, so if you want to use them on a same page, you will need to solve all of the conflicts. As I have mentioned, the jQuery library supports 
noConflict mode, which is suggested to be used with other libraries and if you try to google it, you can find solutions also to 
tricky conflicts between ASP.NET AJAX and jQuery (depends on the error) or useful 
forum posts right on the asp.Net forum.
Best regards,
Juraj Ondrus
