If you use a TabContainer with UseVerticalStripPlacement="True", the script throws an error in IE on this line:
$get(this.get_id() + "_headerSpannerHeight").style.height = spannerHeight;
On my page, spannerHeight is calculated as -67px. This throws an error in IE 8 but is fine in Firefox 13 and Chrome 11.
Note, my TabContainer is empty and I am dynamically adding content to it during Page_Init. I am using Ajax Control Toolkit 4.1.60623.
Comments: Hello, I had the same problem, I solved this change the size of Width and Height of TabContainerControl. I was using Width="100%" and Height="100%" and the number of Tabs on vertical was 17, after I changed the to fix number like Width="700px" and Height="800px". This solved my problem.
