Description reemfz 2016-08-09 21:46:50 UTC

I discovered another bug in the iOS designer in VS.

problem description:
declaring an event handler in one control is replicated across all the controls in the view controller 

steps to reproduce:
1. drag few controls (buttons) into the view controller.
2. From properties, click on the Events tab and declare an event.
3. click on a different control and notice that the same event is also present in that control (or any other ones in the view controller).

when an event handler is added via the designer, it gets replicated across all the controls in the view controller.

event handlers should be control's specific. each control (view) needs to have its own set of control. similar to how xcode declares Outlets and Actions. 
if you want to hook up the same handle to multiple controls of the same type, it needs to be done explicitly.

This should've been fixed as part of https://github.com/xamarin/md-addins/commit/414dc49d7964c7a66c793da718785b7b9c329d96. The issue was the property panel was not updating correctly so it did not accurately reflect the actions associated with the selected control. It should be fixed as part of the next cycle8 release.
