I dont know it it is a bug but when i have a segmentedcontrol1 with the click and indexchanged members generated with designer ( but both are empty) i cant select any segment. I click on it and the selection is not being made. When i delete the empty sub of segmenedcontrol1_click everything works fine.
This is not a bug. The click event is available to all views as all views inherit from the View control. You shouldn't implement it with SegmentedControl as it consumes the click gesture.
