Thanks Erel,
is a important function second me to be implemented
I have another problem, I have the following scenario
B4X:
Dim Device As AHPreferenceCategory
Device.Initialize("Device Settings")
Device.AddList("Interface","Interface","",InterfaceVar,"",InterfaceList)
Device.AddList("Method","Method","",MethodVar,"",MethodList)
Device.AddCheckBox("Port","Select Port","","",PortVar,"Method")
I need the CheckBox "Port" is active only when I select a particular item from the List "Method"
