I want to show a modal popup when a user click on an asp button. The user must select an option of a panel. The value of the option selected must be saved to an input hidden and then the asp.net button must do a PostBack.
Can I do that?
Thank you!
Finally, I've decided to use jQuery to show a ModalPopUp. The following question has the answer to this question:
