WebDataMenu Itemclick event not firing
posted

I have just upgraded to the new SR.  I don't know if that has anything to do with this issue.

I have an AutoPostBack flag set for ItemClick, and I have code-behind on the ItemClick event. 

 





<AutoPostBackFlags ItemClick="On" />

It is a full page postback, and I can see the postback take place.  However, none of the code in the ItemClick codebehind is executing.

I have not had time to fully document....  has anyone else encountered this?

The only thing the least bit tricky is that I have also bound ItemClick on the client side, so that I can cancel the postback on some of the higher level menu items.  Nothing too fancy... I just do eventArgs.set_cancel(true); only for those top-level nodes.  They behave as expected and do not trigger a postback.

    This is a bug... and it is related to the WebDataMenu being inside a WebSplitter pane.

    The following page contains two identical WebDataMenus.  One is inside a splitter pane, and the other is outside.

    Both menus are configured to only allow ItemClick to proceed if a child is clicked.  Both trigger the postback if a child is clicked.  However, the ItemClick codebehind only executes for the WebDataMenu outside the WebSplitter pane.
