    Hi John,

    thanks for replying...

    Heres what I'm trying to acheive.
    This is for an e-mail marketing newsletter. The user enters the product
    ID's in the textboxes at the top of the page (along with layout and some
    other details). These are sent to multiple instances of the user control
    which displays the product in question. This is all graphically displayed
    in a Panel, so the user can see what the e-mail newsletter will look like.
    This all works fine.

    The Panel's html is grabbed via a htmltextwriter and deposited in the
    textarea, this is so any manual modifications can be made and later saved to
    a database for sending at a later date.

    This works partially, the user controls HTML is not being grabbed. I
    presume this is due to the calling of them happening after I grab the panels
    html.

    So where in the page life cycle do I need to grab the panels html in order
    to include the html of the user controls?

    Thanks in anticipation,
