Description Tarun 2017-09-07 18:49:58 UTC
I am creating an UWP app through Xamarin PCL. In my page I have a listview and a native uwp webview(which is rendered through custom renderer) inside another stack layout.

My problem is:- 

When I am running the app in windows laptop which is having touchscreen, the list items items which are currently shown on screen, disappears on clicking or touching anywhere on the webview container. Click or touch at any other location doesn't affect the list.

However list items are present in the list itemssource as clicking on any item cell, app is working as expected. In emulator app is working fine.

I have checked with the long list data, in this case, only the items which are currently in view are disappearing while other items are shown properly as I can see them on scrolling down.

I have created a sample project to reproduce the issue. Link of the project is given below:-

I don't seem able to reproduce the issue on a phone, which presumably should have similar results to a desktop with a touchscreen. I don't have access to one at this very second, but clicking into the WebView does not make anything disappear either. Could you please confirm whether or not the latest 2.4.0-prerelease resolves your issue on your end? Vanishing cell text (in some cases) on UWP was an issue that existed before but should be resolved with that build, although it may not apply to this particular case.

I have tried with latest pre-release and it is fixed. Thanks

Issue was not on phone, it was only on windows tablet (I haven't tried in android and IOS).
