How to use the dialog button's style for asp.net buttons?

How to use the dialog button's style for asp.net buttons?

Hello all,
I've just started to learn jQuery since yesterday so there are a lot to learn. My question is about the jQuery UI dialog:

How can I use the style that was used for the button in the dialog for asp.net buttons? I would like all my buttons to have the same look and feel.

Thank you very much,
Kenny.
