Thanks for SCS's respone and Phillip's continue followup,
So I support Phillip's idea ,however, considering SCS's actual scenario the
structure may not be changed. Have you already built the main page and
those sub pages which will be displayed in iframe? Also, if using Philip's
suggest that use Table to constructure the layout of your main page, you
can no longer use sub pages, we have to use WebControls or
Usercontrols(ascx) to construct the UI. Also, if you've decided to use
Iframe structure, as I've mentioned before, we'll have to utilize
clientside script to do cross frame communication....
So what's your project's current status?

| Hello SCS,
|
|
| You are correct in saying that "if i use IFRAME. All i have to do is tell
| the menu item (which happens to be a hyperlink) that the target is
IFRAME."
| But then you lose a requirement that you put forth at the outset of this
| thread; namely to be able to handle events from the child page in the
parent
| page. I had to do the same in a previous project (the website of the City
of
| North Vancouver, a municipality in the province of British Columbia,
Canada
| ). So maybe I should use it here as a case study.
|
| If you look at the City of North Vancouver ‘s website at
http://www.cnv.org,
| you will see that it has thousands of pages (that used to be separate asp
| pages before I redesigned it). Now it is only one web form in asp.net
|
| The page is divided in separate areas managed by custom server controls;
one
| for the top menu (that is dynamically generated out of an oracle database
| updated momentarily as a new page is added to the site), a footer, a side
| menu (that appears a tree with collapsible/expandable items) and a
content
| area (which is similar to the child page that you intended to place in a
| frame).
|
| By using one page, I manage to process events from the content area
within
| the parent page. The content area does not only display static HTML
content
| but also applications as in this link
|
http://www.cnv.org//APPS/PROPERTY_SEARCH/
|
| In summary if you want to process events, server-side, from the content
page
| to the main page then you have no option but to think of the content page
as
| a control. Technically any function that you can carry in an aspx page
class
| you can convert to an ascx without any loss of functionality. As for the
| display considerations, you can use cascading style sheets to achieve the
| final look and feel of your site in ASP.NET 1.x
