Try removing the AutoPostBack
property as it is not needed.
I have used TabContainer
before and there is no AutoPostBack
Please let me know if it works for you or not.
If it will not work for you, then I have some links with me to do it in an other way... I will post those here by Improving my Answer.
I have searched for your issue and after a lot of research what I found is...
-> When Page directive autoeventwireup is true and you attach an event OnInit to things like Page_Load, those events will be raised twice, making it look like double postback. It could be semething else, too.
-> The problem also occurs when you have TabContainer
inside one UpdatePanel
, which is, I guess, your case.
1. Set AutoEventWireup to false (this will also disable some custom control that was wired up)
2. For those who required AutoEventWireup
to be true, just make sure all post back controls or buttons should not be server controls, instead they must be standard
tags and should NOT have
. Now you have to remove AutoPostback
you will find a lot of links...
Just try to implement and let me know...
