Eric,

that looks very helpful, thank you!

>If you've specified a class you can use jQuery's selector functionality to apply the mask to all the elements on the page that use that class (or start with/end with a certain string, which is what I do for date fields so they automatically get a nice datepicker functionality). eg (still in the HEAD of the master page)

>     <script type="text/javascript">
>        $("document").ready()
>        {
>            $(".phone").mask("(999) 999-9999");  // Masks all element with the class='phone'
>        }
>     </script>

>Alternatively, and this works best if you put it on the specific ASPX page that has the control, you can specify by id

>     <script type="text/javascript">
>        $("document").ready()
>        {
>            $("#HomePhone").mask("(999) 999-9999");  // Masks the element with the id='HomePhone'
>        }
>    </script>
