I'm sorry the title should be "Pull to refresh",
When the user pull the scrollview down, i hope there's an event rise so i can refresh or do something else to the scrollview.
Sub ScrollView1_ScrollChanged(Position As Int)
End Sub
This Sub is called when the user scrolls. Just check the position and do you stuff. Check if the value is < 0 or > panel.height to start the refresh/update.
