Closed Unassigned: Tabs Issue in AJAX [27783]

Hello All,

I am working on ajax tabs; after successfully implementing I am facing the below problem

I have added two tabs at design time ONLY

1. Inbox : Set to Visible True

2. Settings: Set to Visible False

then I have 'Add Tab' button which will add the dynamic tab to the existing tab container; while doing this my Inbox tab is getting hide automatically and style is getting applied to that(Inbox) tab like display:none;visibility:hidden.

Because of this my entire tab container is not getting visible and also new tab is not visible ?

Why I am facing this issue ? I am not able to find the solution on this;

I am using Visual Studio 2012 with framework 4.0
and AjaxControlToolkit dll version :-3.0.20229.4549

Any help on this really appreciated.
