Refreshing a parent window from child.

[Guest]

greetings,

this is the code i use to refresh a parent page from the child if it closes
and it works... my problem is, when the parent page refreshes; all my default
values in the textbox are being cleard away... how can i persist the
viewstate?

<script language='JavaScript'>
window.dialogArguments.location.reload(true);
window.close();
</script>
