GitHub is here: https://github.com/anagram4wander/VirtualizingObservableCollection
So, what to do about it? We made one ourselves – the VirtualizingObservableCollection, which does the following:
◾Implements the same interfaces as ObsevableCollection<T> so you can use it anywhere you’d use an ObsevableCollection<T> – no need to change any of your existing controls.
◾Supports true multi-user read/write without resets (maximizing performance for large-scale concurrency scenarios).
◾Manages memory on its own so it never runs out of memory, no matter how large the data set is (especially important for mobile devices).
◾Natively works asynchronously – great for slow network connections and occasionally-connected models.
◾Works great out of the box, but is flexible and extendable enough to customize for your needs.
◾Has a data access performance curve so good it’s just as fast as the regular ObsevableCollection – the cost of using it is negligible.
◾Works in any .NET project because it’s implemented in a Portable Code Library (PCL).
See the version list below for details.
Install-Package VirtualizingObservableCollection -Version 0.9.0
dotnet add package VirtualizingObservableCollection --version 0.9.0
<PackageReference Include="VirtualizingObservableCollection" Version="0.9.0" />
paket add VirtualizingObservableCollection --version 0.9.0
Minor change to Async GetPlaceHold to pass in the index
Re-worked the Add/Append implementation to create new pages..
Async seems stable now: Implement IPagedSourceProviderAsync<T> and pass that to the PagingManager constructor.
Changed rest of the DateTimes to Object so you can implement any type of IPageExpiryComparer you want.
