Description Owen Stewart 2011-10-12 12:20:31 UTC
I've run into problems with the UISegmentedControl when using it with IOS5 on the IPhone. When I update the SelectedSegment property in code the ValueChanged event is not invoked although the visual indicator changes on screen. 

If I touch a segment then the ValueChanged event is always fired.

If I run the code on the simulator for IOS5 it works correctly. It's also working on IOS4 devices/simulators too.

My setup is IOS5 GM (9A334), MonoTouch 4.2.2, Mono 2.10.5, MonoDevelop 2.8 and Mac OSX Snow Leopard

Please provide a test case, as it is not possible to determine what you are doing from the description.

If I had to guess you are mixing Delegate setting with event setting, and that is not supported, you have to pick one or the other
