Once EnableViewState of WebDataMenu set to "true", any postback inside Content of Master's ContentPlaceHolder will raise error : LoadViewState_Exception.
However, I found that this error can prevent by set the EnableViewState to 'false', but any posback inside Content of Master's ContentPlaceHolder will make previously binding Items of WebDataMenu disappear.
I no sure whether this is bugs or not, but I need Item of my WebDataMenu keeping there after any postback and without error of "LoadViewState_Exception". Thank for help !!!

Hi, I am using Infragistic for ASP.Net 2009 - 9.2.20092.2137.
Hi there,
can you tell which version of WebDataMenu control are you using? I've seen such a bug in the past and the problem was that the menu items were generated dynamically in the code behind and then added to the control. If you have the same issue you have to upgrade to latest service release. If not please contact developer support to help you resolve the issue.
I tried this code in a master page and works just fine.
Hope this helps.
Thanks,
