Hello
I encounter a problem migrating for fx10 to fx11. the compact framework 1.1 has a different behavior from th
previous framework 1.0 when working with combobox
I give hereafter the code used with FX10 and FX11, it works under FX10 and not in FX11. I tried to found a solution
but currently I solve the problem in simple program, but in a complex application with multiple screens
the behavior of the combobox is variable.
I've build the program using the VB.net help, the behavior with FX11 is not documented
Do i do something was wrong
Has Someone is solution ? Because It brings me sleepsless nigths !!!
Thanks for collaboratio
