Session data

[Guest]

Hi,

I am developing an application with framesets (header, left navigation, and
content). Each frameset loads an ".aspx" page, and in one of these pages, I
store some information in the Session object, as follows:

....
Session["ABC"] = false;
....

When the page has finished loading, I click on a link button that opens a
Modal window, in which I am trying to access the Session information stored
before. However, this does not always work. Sometimes, the Session object is
empty and the information not available. I am not using Output caching.

Do you know what the problem could be?

Thanks.
Mike

The problem is simple each frame acts as a instance of browser so instead of
sharing the session there might be instances where it sort of gets messed
up.
Avoid using frames if possible. User controls are a better approach to the
solution

Hi Dave,

Thanks for the explanation.

What if I would store the information in the Application object and then
store in the Session object of each page in each frame?
Unfortunately, I cannot change the page layout, so I need to stick to frames.

Thanks.
Mike

was i would suggest is that if its common data to be used between number of
users only then consider application / cache.
Infact use Cache object instead of using Application object.
Also put checks in your code before you access session variables

int myInt;
if(Session("variable") != null)
{
// then read it
myInt = (int)Session("variable");
}
else
{
// fetch the data again say from db or xml file or whatever datastore
you use
myInt = myclass.mymethodcall();
}

you can still keep the same layout. as the page using user controls.
say you have your top menu / left hand menu.
copy the controls from that page and put it in a user control.
now in your main page. say use a table set the column and drop the user
control.

I see what you mean.

Just an additional question. Is the Session object stored for each pages?
So, in my case, each of the ".aspx" pages in each frame could contain a
different Session object. Is that correct?

Thanks.

not always... its a client side thing.
if done in a proper way they should and would share the same session cookie
but you could have instances where it all goes horribly wrong and each might
have its own session.

Mike,

How are you storing your session information? In process, session state
server or Sql Server? I used to have similar problems, but switched to Sql
Server to manage state and don't have issues anymore.
