hi Bonj,
You are confusing server side and client side, the Page_Load event occur in
the server side, the objects from the client side (frames, documents,
windows, etc ) do not exist.
If your header page decide the content of the main page you need to
implement that functionality there, you can do so in different ways, if the
page to load & its parameters are decided in the server, then you have to
send this info back to the browser, where a script can read it and set the
correct src of the main frame. the other way to do it is if when you load
the header you can decide what the possible source of main page will be you
can use LinkButtons for example with the correct properties value set.
regarding your doubs about global/session variables:
If I use a global variable, will it be guaranteed to have a unique value
in the memory of the web server for each user?
there are not global variables, they need to be either in
Session/Application collections or as a static member of a class used, in
anyway its value will be shared among ALL the users of the application
If I use a session variable, will it be reliable enough to be guaranteed
not to have been "relegated out of the session" by the time the property
between the <%= ... %> comes to read >it?
A session variable will exist as long as the session exist, it will never
happen that a variable exist when you start processing the page and timeout
before you finish processing it, the only way to end a session is either you
call Session.Abandon or a page is not requested in a given timeframe.
Hope this help,

news:D7**********************************@microsof t.com... Hi
I've got the following problem - I need to have an aspx page with two
frames, although the question isn't necessarily about the workings of the
frames, more session variables... the frames consist of one header (not
resizable) and one main (resizable). The source for the "main" page needs to
be of the form "WebForm3.aspx?...." with parameters to be determined at
runtime. I'm ok with this, I've gone down the route of putting src="<%= MainPageToDisplay %>"
but what about MainPageToDisplay - the info it needs to access can only be
decided in the Page_Load event - so I was wondering which out of a global
variable and a session variable are the most reliable to store this
information, for instance my dilemma is as such: If I use a global variable, will it be guaranteed to have a unique value
in the memory of the web server for each user? If I use a session variable, will it be reliable enough to be guaranteed
not to have been "relegated out of the session" by the time the property
between the <%= ... %> comes to read it?
Thanks for any help, would really appreciate this one clearing up!
Thanks.
