We have a problem with only the Android version, iOS is fine.

 

On a very complex Cell UI and using a Selector, often the Labels are rendered 1 letter wide. Rotating the device Landscape then Portrait causes a refresh and the labels render fine. Pull-to-refresh will also often fix the issue. The initial render fails.

 

How can I force the RadListView to recalculate the layout of the cells so that the Labels redraw. I can do that in a timer after the data is loaded. A work around.

 

 

Hello Ian,

We've been reported a similar issue with inaccurate measurement of ListView items on Android, you could find the bug report on our public portal below:
https://feedback.telerik.com/xamarin/1366399-listview-android-inaccurate-measure-when-pull-to-refresh-is-enabled

If that's not the case you have, can you try to isolate the issue in a sample project and send it to us? We will need to reproduce the issue at our side in order to test it and investigate it further.

As to the question about forcing cell layout update - If the ItemsSource of the RadListView is bound in TwoWay mode and the underlying collection is ObservableCollection, the ListView component should be automatically updated whenever the collection changes.  So, basically, you could use this approach to recalculate the layout.

I am looking forward to your reply.

Regards,
Yana
