Hi,

If I got you right you want to play with div visibility on parent page
after called (dialog) window return values back to the calling page. if
this the case its better to achieve it using client side script and
DHTML. Round trips to server are useless here.

if you want server side event on calling page to be happened when dialog
window return value you can use client side script by submitting form or
calling __DoPostBack with right parameters and cause post back.
