Hi All,
I create some app on the web with c# (asp.net) and strataframe.
I have a lot of user which start a webform to add a new record, when i click on new , i make : "this.MyBo.add()"
They make other things, during more 20min, and the get a error when they validate their form.
I know , that i get grow up the session, but it's not recommandate on the web.
Why Strata store in variable Session ? not in the viewstate Session ?
Have you a solution for this problem ?
Thanks Olivier

We use the Session because the business objects can get pretty large, and we didn't want to run into the maximum HTTP request size limit. However, the business objects are serializable, so they can certainly be stored in the ViewState. To do this, build your own BasePage and don't use the StrataFrame one. Create it by copying the one from the StrataFrame source code. It's only ~300 lines of code, and everything will stay the same except for the InitializeBusinessObjects() method. There are 2 references in there to the Session, and you can change those to ViewState. That method is not overridable, otherwise, you could just override it rather than having to re-create the BasePage class. Which is certainly another option: modify the source to make the InitializeBusinessObjects() method Protected Override and override it to store the BOs in the ViewState rather than the Session. I'm thinking this is an implicit enhancement request to be able to store the v2 entities in the ViewState, no?

Hello Ben,
May be, i explain myself very bad.
I don't know if we store Strata on Session or Viewstate it's better.
But , i don't want to depend the limited time , for my user.
I mean, i want to understand how Entity framework work with asp.net and if my problem will be resolv with Strata 2.0.
Does Entity depend some variable session ?
If the user add new record and my app can load their session with cookie, to during more 24 h if i want.
If the user add new record with entity it's work without session or not ?
Strata will be fusion with entities ?
It's possible if the session is expired do not lose the value in textbox , to reload Bo to make an Add() ?
thanks for your help, i have many question about stroke with strata and the web .
ben

Hi Ben,
I'll translate your answer on the French speaking SF forum, and I'll come back here if we need more help.

Thanks, Michel. I was thinking about the problem over the weekend. To store the business objects in the ViewState, you would need to modify the source code or copy out the source code and create your own BasePage class that works similar to the SF one. If he wants to store the variables in the session, he could increase the session timeout and move the session state storage to SQL Server to preserve resources on the server.

Hello I get a idea about the solution. It's possible like foxpro and cursor temp to store in Xml (dir temp for each session) or Sql Server, the state of Bo Stratra. We can set up timeout on parameters Bo, if the temps are too old strat delete this. It's a real problem, i understand we have plus to save the state session against entity or other bo. But we need to understand , it's not the best way to work in the app web, only in winform. Please accept my enhancement to have no problem with my user. I know we can save on sql server session, but i use the classic session in proc , the problem is only for stratra http://msdn.microsoft.com/en-us/library/ms178586.aspxDo you know a simple way to save a Bo in xml file ? Can you read the third post here ? http://stackoverflow.com/questions/1725925/how-to-set-session-timeout-more-than-20-minthanks Olivier,
