[Bug] Crash if using CarouselView in ScrollView

SymxnCreator opened this issue 5 years ago · 16 comments

Hello,

If I place the CarouselViewControl inside a ScrollView, the application crashes when the page is initialized.
I get the following exception: System.NullReferenceException: Object reference not set to an instance of an object.

Can you fix that?

Is this Android or iOS?

I was able to fix the crash but, i am facing another issue, kind of the same it happens with StackLayout.

In Android, as ViewPager has its own ScrollView, wrapping the Carousel into a ScrollView stop it from propagating HeightRequest and it shows up blank.

InstantiateItem is never called.

I'm facing the same issue here, though I'm not directly using ScrollView but SfPdfViewer (and it's using ScrollView).

Any solution? Actually I am surprised to see people still commenting here as last Nuget update is from 2018. Any way to update to the last version with fixes?
