Description Jon Douglas [MSFT] 2014-11-12 15:23:30 UTC
Created attachment 8706 [details]

From a customer:

When I add a basic listview to the screen I am working on, it looks as
expected on iOS and Android, but on Windows Phone it turns the background
color of my entire view black, and adds a lot of extra scrolling space.

This is the only code I added to my view:

var listView = new ListView();

listView.ItemsSource = new string[]
"item 1",
"item 2",
"item 3",
"item 4"



which makes it go from this (left) to this (right).

I've created a reproduction attached with a few comments in the QuotePage.cs to show the differences.

I have checked this and I am also able to reproduce this issue.

When I deploy the attached project I observed that in windows emulator it turns the background color of entire view black, and adds a lot of extra scrolling space. I also observed that after upgrading to Xamarin.Forms. the background color of view is working fine but the scrolling problem is still exists.
