Hi,

I am setting the Start and End values based on the gauge value,  on property changed event. Some times while setting End values i am getting Monotouch Exception.

Can Anyone help?
 Here is the exception

Hi,

Thanks for reply,

Unfortunately I am not able to reproduce the crash in sample app, but from my application its throwing exception when setting end value and I cant share those code.

I tried to add try catch it works fine in simulator but when I run the application in device app will crash.

I will try to reproduce the crash in sample application.


Regards,
Shashidhar K.
