asp.net textbox validation

Hallo everyone,

I am trying to validate an ASP.NET Textbox but the validate plugnin doesn't work.
As far as I understand, the validate method works with the name parameter of html tag.
Unfortunately ASP.NET server control do not have this property, just ID , that is perfectly working as reference for normal Jquery.

Any idea how to validate ASP.NET Textbox?
