ListView/TextCell with Transparent Backgrounds

Hi

I'd like to have a ListView which has transparent Background for both the list control and items.

I currently have a ListView which is using a TextCell to render each item.

var cell = new DataTemplate(typeof (TextCell));
cell.SetBinding(TextCell.TextProperty, "Name");

_list= new ListView()
{
BackgroundColor = Color.Transparent,
ItemTemplate = cell,
BindingContext = this
};

Unfortunately, the background for each item is still white. Is there anyway to change this?

Thanks,
Ant
