Description Anubhav Ranjan 2015-04-17 07:10:06 UTC
One of our customers is facing issues with Group Header Text Color in List View.


I've got a really simple list view that is trying to take advantage of
group headings:

ListView listView = new ListView
IsGroupingEnabled = true,
GroupDisplayBinding = new Binding("Name"),
ItemTemplate = new DataTemplate(typeof(TextCell))
Bindings =
{ TextCell.TextProperty, new
Binding("DisplayName") }
ItemsSource = categories

listView.ItemSelected += ListView_ItemSelected;

Content = new StackLayout
Children = {
new HeaderControl { ContextText = string.Format("Select
a Milestone"), Style =

When I first load the list, it looks great:

If I scroll down and then back up, all of the group headers lose their coloring:

I just upgraded to the latest NuGet package ( and this still repros.

Test case (cleaned-up and attached directly to the bug)

I was also able to reproduce this issue using the test case from comment 2. In case it might be more convenient, I have updated the Xamarin.Forms package versions, deleted the `bin`, `obj`, and `packages` folders, and re-attached the test case from comment 2 directly on the bug report.

## Steps to reproduce

1. Run the attached test case on Android emulator or device.

2. Scroll the list view so that 1 new group header text appears on screen. (Or scroll 1 of the initial group headers _off_ screen, and then scroll it _back_ on screen.)

## Results

- When the app first loads, the on-screen group header text is _white_ while the other list items are _blue_.

- After step 2, the group header text that was moved from off-screen to on-screen is _blue_ rather than _white_.

## Expected results

Off-hand, I'm not sure if the intended behavior is that the group header text should always be _blue_ (which would mean the initial state when the app loads is incorrect), or if the group header text should always be _white_ (which would mean the state after scrolling the list view is incorrect).

- On iPhone 5s iOS 8.2 simulator, the group headers are black text on grey backgrounds, while the list entries are black text with no background.

- On Windows Phone emulator, the group headers are white text on blue backgrounds, while the list entries are white text with no background.

- The text color does _not_ change on iPhone or Windows phone after the group header text has been moved off-screen and then back on-screen.

Per comment 4, I'm confirming, updating the XF version number, and marking this as Android-specific.
Comment 6 Jason Smith [MSFT] 2015-07-08 06:52:16 UTC
Should be fixed in 1.4.4-pre1
Comment 7 Parmendra Kumar 2015-07-20 08:13:20 UTC
I have checked this issue with X.F 1.4.4-pre2 and its working fine at my end.

Hence closing this issue.
