        'Log("landscape")
        Root.LoadLayout("Lu_ScrollView")
        'ScrollView1.Top=0
        ScrollView1.Panel.LoadLayout("lu_ASViewPager")
        ScrollView1.Panel.Height =Root.Width + Root.Height+50dip
        'ScrollView1.Panel.c
        ASViewPager1.Base.Height=Root.Width + Root.Height '900dip '100%y 'ScrollView1.Panel.Height
        'ASViewPager1
    Else
        Log("tool")

I'll explain what I'm trying to do.
I load many photos to ASViewPager
When the phone is in portrait mode, the image expands on each screen.

Here I need to load ASViewPager on ScrollView
So the user can go down the picture.

you can also simply increase the height of the item in the xCLV when the screen rotates, you don't have to put the ViewPager on the scrollview.
