I have radcontextmenu where some items have custom attribute "ConfirmationMessage" with a value like "Are you sure you want to delete?" These attributes are set on the server code-behind on load.
It works on the first load of the page, but the attributes are lost after ajax/postback.
Please advise a fix or workaround. I am already using the Text, Value properties. Is there some clever way to use the NavigateURL field without causing it to try to navigate to a page?
