Hi Viktor,

Thanks you for the detailed update.

I checked the ig_webtab.js and below is the header of that file:

/*
* ig_webtab.js
* Version 8.3.20083.2039
* Copyright(c) 2001-2009 Infragistics, Inc. All Rights Reserved.
*/

I just found the comment line //vs 1121808  from this file. It seems that the second change was not included in this version of js.

Regards,

Chu

Hi Nguyen,

I checked content of ig_webtab.js in 8.3.20083.2039 and found that is has a partial fix. There were 2 changes to codes which were releated to scrollbuttons when tabs are hidden on client. The hot-fix was released in 3 weeks after 2nd change, but it was built from source codes before that 2nd change.

That second change (which was not included in 2039) was done for issue when scrollbuttons were disabled after 1st tab was hidden. Your description about reappearing tabs match with first part of fix, so, I am not sure if 2nd change is related to your application.

Please ensure that correct version of ig_webtab.js is used. You may check it, if you debug application and look at files within list of Script Documents. At the top of ig_webtab.js file you should find name of that file and build version. There is also should be a comment line with date like

//vs 1121808 (12/18/2008 - first change)

//vs 123108 (12/31/2008 - second change)

//vs 111408 (11/14/2008 - previous version)

If your application at run time uses ig_webtab.js version 2039, then it would be great if you attach your aspx (within Options tab) which can be used to reproduce that issue.
