I was searching for some time how to update single list view item only when item properties change, not the list of items itself.
I came up with a simple solution by implementing CustomObservableCollection: https://github.com/kornerr/TestApp/blob/master/TestApp/CustomObservableCollection.cs
It contains special 'ReportItemChange' method which tells all interested parties of the update (by generating Replace event).
Here's full source code: https://github.com/kornerr/TestApp
I used Xamarin Studio 5.10.3 (mid 2016) and tested the app under iOS Simulator.
Unfortunately, this error is still happening.
I logged in at testcloud.xamarin.com, clicked on "Support" and submitted this issue.
I also referenced this thread and Peter's bug in Bugzilla.
@abeLuna - NuGet has a user interface that is very confusing. Even though I know this, it still catches me out occasionally. Could you be looking at the version number of the update rather than what you have installed? That's what I do occasionally.
When you click on the Updates tab, you will see a list of packages on the left of the screen, with the version number of the update (not the version number you currently have installed) next to the package name. It's only when you click on one of these that the right hand side is populated with the details of what you currently have installed. It's in this right hand side section that you see your current version number(s).
My little tutorial site. What I say there is "Choose PCL until you have a specific known need for shared". If you are on VS2017 you'll see ".NET Standard" in place of PCL. Chose that.
They actually added a PlatformSpecific for this.
I'm using Firebase Cloud Messaging for my push notifications. I was able to accomplish this using dependency services, since there were a few times when I wanted to clear all notifications based on what page the user was currently on. Here's the basic idea you may need to tweak it based on where you're calling this from.
Here's the implementation in the android service:
public void ClearNotifications()
NotificationManager manager = (NotificationManager)Android.App.Application.Context.GetSystemService(Android.Content.Context.NotificationService);
Here's the implementation in the iOS service:
public void ClearNotifications()
if (UIDevice.CurrentDevice.CheckSystemVersion(10, 0))
//TODO: Check if this will only work on 10 and up
If you need more info, or the complete dependency services, feel free to ask...

Hi @ParmeshAlthi ,
Hmm, downloaded and ran the sample and I did not see any empty rows after the for populated rows. Removing:
made the empty rows show again, so I am not sure what might be going on on your end. Can you post your full XAML code?
