    [CLOSED] Checkboxes in CheckBoxGroup

    Hi all,

    a very simple task I can't solve. I need a "select/deselect all" fn.
    How do you retrieve checkboxes (and their values) from a CheckBoxGroup?
    I saw example Form -> Group that does it via server side, how can I do it client side?

    How about RadioGroup? Should be the same.

    Thanx

    Matteo
