Hi Stephane,
I have created the sample for the PullToRefresh XamarinForms feature. The file-size was large so uploaded to google drive and find the below link.

https://drive.google.com/open?id=1YzhrE9xH8GBJslEbzUEhtTyncsZAE1uP

As per XamarinForms docs, I have added the below code to enable the PullToRefresh feature:-

IsPullToRefreshEnabled="true" RefreshCommand="{Binding RefreshCommand}" IsRefreshing="{Binding IsBusy}"
Next, RefreshCOmmand is added in the ViewModel

Issue:- Trying to pulling down the list view but Refresh command is not getting called.

Please suggest or correct me if anything more need to be added to get this working.

Looking ahead for your quick reply.
Let me know if you are facing any issue while dowloading the sample from the google drive.

@PandeyAlokKumar you still haven't been clear about the platform on which this happens

[PandeyAlokKumar]

I am currently checking on UWP platform.

Pull to refresh is not implemented in UWP at the moment. this explain why it doesn't work...

[PandeyAlokKumar]

Any alternate approach to achieve this on UWP platform?

[jbpoulsen]

I guess you should just add a button above or below the ListView. Alternatively you could add a ToolbarItem and let that call your "RefreshCommand". I'm currently debating this issue myself.

[jbpoulsen]

Just as a side node, beside adding a refresh button, I have actually also created a custom renderer for the ContentPage to intercept KeyEvents, so hitting F5 will also refresh the data in my listview. Works like a charm.

UWP supports this now - as of Windows 10 build 1803: https://docs.microsoft.com/en-us/windows/uwp/design/controls-and-patterns/pull-to-refresh

Looks pretty trivial to wire up too. Would be good to get this added to XamForms.

[jlf0dev]

Any update on this? or @nbevans did you find a workaround?

Edit: For those interested, Xamarin Forms 4.3 introduces RefreshView that can be used on ListViews

[paradisehuman]

@StephaneDelcroix Any updates for using PullToRefresh in UWP desktop mode? It doesn't do anything on desktop mode.

[samhouts]

Please try the RefreshView instead. Thanks!

Is ListView deperecated now?
