Message: Sys.ArgumentUndefinedException: Value cannot be undefined. Parameter name: type Line: 2705 Char: 12 Code: 0 URI: http://btstdv-sps01/ScriptResource.axd?d=xaqw4kfdwdWtvHW4JHRwu9dPHBZGWnnEsHrQAeYOVMQ7UJ-eBupaWW3i-HcJkIVjOLsVpXh5bEw8C3og-zVo6TrkPpdFBh_IX0nO69bBYU01&t=ffffffffec2d9970 Then although the TabStrip and the matching TabPage is shown I can't change tabs.
I notice that I don't get this error if the TabStrip is either visible to start with or not in the UpdatePanel (ie a full postback to make it visible).
Is there some javascript that runs on page load to initialize the TabStrip? if so can I fake it some how?
