Question

I have a ListBox with Height="515", when I turn my application, part of this ListBox is offscreen.

How to specify that ListBox’s Height in landscape orientation should be, for example, 350 px?

Answer 1

Detect orientation change

private void PhoneApplicationPage_OrientationChanged(object sender, OrientationChangedEventArgs e)
    {
        if ((e.Orientation & PageOrientation.Portrait) == (PageOrientation.Portrait))
        {
            listbox.Height = 515;
        }
        else
        {
            listbox.Height = 350;
        }
    }
