Hi,
In my ASP .NET application I use a tabpanel to let the user open
multiple subject from a quickbar, like browser tabs but then inside my
application. The content of the subjects is dynamically created
server-side. To remain the viewstate of inactive tabpages
I need to rebuild the content of the inactive tabpages every request
again. When the user opens more subject very request to the server will
take longer and longer because of this.
I'm looking for an advanced solution to save the viewstate of inactive tabpages over multiple requests on the active tabpage. When an inactive tabpage becomes active again I want to put the saved viewstate of this tabpage back in the viewstate of the whole page. This can give my application a performance boost when I do not need to rebuild every inactive tabpage on every request to the server.
I have red a lot about the ASP viewstate but I did not found a
solution for this yet. Any suggestions how I can accomplish this?

When adding content dynamically it should be added to the page controls collection upon every post back, otherwise it will be lost. In the scenario that you are trying to implement only the content of the dynamic tabs should be added to the controls collection of the page. Please refer to the following article here regarding Dynamic Web Server Controls and View State

I know the rules about creating Dynamic content and how to keep the viewstate fore those controls. That works fine for my now, but I want to save memory and gain performance every request by doing it smarter.
I would like to save the viewstate of an inactive tabpage in the session and put it back in the viewstate of the page when the tabpage becomes active again or something like that.
Any suggestions how I can accomplish that?
Please refer to the following article by Scott Hanselman explaining how to save the ViewState into a session variable.
