Hi Jim:
iOS is supported but the available gestures are limited. That's why it doesn't support all the interaction options that are possible on the desktop.
On events, it supports two actions:
- tap (translates to EventClick event)
- press and hold (to activate event moving), than drag to a new location
Unless you map the event bubble to event click (EventClickHandling="Bubble") it is activated on mouse hover. This is normally not possible on iOS.
There are a few options:
- map the click event to context menu and list the options there
- add permanently visible active areas to the event and map the bubble activation to one of them
