I am sorry, my English is not good!
This question is on the ListBox SelectionChanged event, in the absence of compilers, operating normally, but in the compiler, the incident can not respond! Why ? Is PPC does not support this event?
ListBox_SelectionChanged event works normally, in the IDE and compiled on both desktop and device.
Can you post your code to see what happens.
What do get ? An error or nothing or what?
