I have programmatically created a Scrollvew object called Scrollview1 in Sub Globals (Dim ScrollView1 As ScrollView). It is later initialized and a layout is loaded into it. I created an additional Sub called ScrollView1_ScrollChanged(Position As Int) at the very bottom. When I set a breakpoint in this function and load the debugger, the function never gets called when I use my finger to scroll the scrollview on my Android device.
The event takes its name from the Initialisation parameter and not the variable name where it is declared because variables can be reused for other instances. Check the event name you are using in Initialize.
