Internal method _loadChildrenFromWebService() - problem on mobile devices since Q3

[Andrew]

Our website uses a system of pre-caching child menu items to increase performance on a very large webservice-populated RadMenu. When a menu item is expanded, all child items invoke _loadChildrenFromWebService() to fetch its own children, in advance of that sub menu being expanded. This has worked incredibly well up until upgrading to the Q3 and Q3 SP1 Teleriks. Now - on desktop browsers, the behaviour is unchanged, but on Android phones (multiple browsers tested), when _loadChildrenFromWebService() is called - the sub menu filled from the webservice actually displays! Alternatively, on Windows Phone 8, the menus pop up, and are immediately hidden.

Has the internal behaviour of this method been changed in the recent updates?

Hello Andrew,

Indeed with the latest release of the controls we implemented various improvements of our controls related to their functionality in touch devices. We already have several bugs that have been reported and our developer team is working on resolving them. Can you please send us a very simplified runnable project that we can test locally and inspect the issue that you have thoroughly? Can you also specify the steps needed for reproducing the behavior that you get?  

Regards,
Kate
the Telerik team
