A Long expression that specifies the color (RGB color) to be applied to the
host's background.
By default, the BackgroundColor property indicates the
NAVHost container's background color. Use the BackgroundColor property to
apply a different background color to the NAVHost control. The BackgroundColor
property does not change the background color of the hosting control. To
change the background color of the hosting control, you need to consult the
hosting control's documentation, and use it in a Template
or Item property like in the following
samples. Most of the controls provide a BackColor property that change the
control's background color, and so that's the property it must be used to
change the hosting control's background color. The BackgroundColor
property changes the background color behind the hosting control.
