Hi,
i have the exception:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
Everything is working correctly when i don't use the event OnTabClick.
But I need it and when i try to attach a function to this event (either from the markup or the code behind) i get the exception above.
the hierarchy of the markup is as follow :
asp:panel
RadAjaxPanel
RadTabStrip
RadMultiPage
div
table
tr
td
RadAjaxPanel
RadTabStrip
RadMultiPage
The markup is :
when i tried to attach the event from the code behind i did : (when i did i remove the argument OnTabClick from the markup)
the function that i need to call:
Hope you can help me
Thank you
