Description Anubhav Ranjan 2015-07-22 10:13:42 UTC
#Description: 
===========
We try to use a ListView with ViewCell and components having a different background color, but we encounter a problem when an item is selected in the list.

In IOS, when we click on an element, the background of all ViewCell children’s are replaced by the default selected color.
On Android, if we put in the XAML a background color on a child 's ViewCell it is not overwritten.

Comment 3 Damien B. 2015-11-27 06:08:06 UTC
Hello,

I want to know if a fix is ​​planned in future releases of Xamarin.Forms because it is always present with Xamarin.Forms 2.0?

Regards,
Comment 4 Jason Smith [MSFT] 2016-04-11 09:19:33 UTC
There are currently no plans to fix this in iOS. iOS overrides the background color settings at the toolkit level. If you want to prevent it you have to use a custom renderer and override the draw method (or add a layer to its CALayer). Both of these solutions come with a performance overhead.
