Updating Multipage height

[Guest]

Hello,

I have an aspx page with a Multipage webcontrol. In 1 Pageview i have an
iframe which directs to another aspx (InfoEdit) page. On this InfoEdit page i
have a datagrid in which data can be loaded through a user search. I want to
dynamicly update the height of the Multipage webcontrol depending on the rows
in the datagrid, but how can i trigger a routine on the main page which does
that? And how can i pass a parameter to that routine with the height i want
the Multipage to update to?

Or can i use a Session variable Session("MultiPageHeight") and do something
in the Page_Load event of the Main page? And if i use this method how can i
trigger a postback to the Main page from the InfoEdit.aspx?

Is there anybody who can help me with this?

Many thanks,
Dennis
