The DeviceChanged event is fired whenever there is a change from one device size to another.
In this example, a different layout is applied based on the device:
Evtroutine Handling(#Sys_Web.DeviceChanged)
Case (#Sys_Web.Device)
When (= Desktop)
#Com_owner.Layout <= #LayoutDesktop
When (= Mobile)
#Com_owner.Layout <= #LayoutMobile
When (= Tablet)
#Com_owner.Layout <= #LayoutTablet
Endcase
Endroutine
