This probably has been asked many times before but I was wondering how to maintain the ActiveTabIndex of an AjaxControlToolKit TabContainer.
The only way I can think of achieving such a thing is to store the ActiveTabIndex in the session and checking for this on postback. Are there any other solutions to solve this problem?
Most likely this answers your question. Such things belong into the ViewState of the Page when their not already saved there.
EDIT: On the other hand: i've tested it and my ActiveTabIndex maintains on (asynchronous) postback.
