Extension of the ASP.NET Portal Starter Kit

[Jill Graham]

Hi,

I'm looking at the ASP.NET Portal Starter Kit.
All pages within the application are redirected to the DesktopDefault.aspx
file.

The DesktopDefault.aspx file defines the layout of the page : a banner on
top of the page and three panes (leftpane, contentpane, rightpane).

I want to adapt the Portal as follows :

The site will contain a total of about 500 pages. Each page will have a
unique pageId.
Each page can have a different layout (i.e. a different template file = a
different desktopDefault.aspx file).

We want to create 1 starting page, for example start.aspx
(start.aspx?pageId=147).
The start.aspx file extracts the pageId from the querystring and looks up
the template to use (i.e. the desktopDefault.aspx file to use) in the
database.
The template file (i.e. the desktopDefault.aspx file) should be loaded
dynamically.

Does anyone has an idea how to implement this ?

Any help would be appreciated and (maybe) rewarded.

Thanks
