Vertical scrolling not working for CarouselView and CustomLayouts

[ShariatPanah]

Description

so when I have a vertical scrollview on my page that:
1. has a carouselview as one of its children at the top (I assume this happens to CustomLayouts too)
2. and at the bottom there is another scrollview with horizontal scrolling
I'm facing a problem, when i scroll down by touching the carouselview, it works fine, but when i iterate over the bottom scrollview (horizontally) and want to get back up there by scrolling vertically using the CarouselView it doesn't perform the scrolling until I touch the bottom scrollview and going a little bit vertically, then i can continue scrolling up by touching the carouselview.

NOTE: as I said before I think this happens to CustomLayouts too, please check that yourself or let me know to create a sample for it also

I'm attaching a screen recording and the sample project below

and by the way, the backgroundcolor of frame or even the label in the carouselview datatemplate doesn't show the color that is binding to, maybe I'm doing something wrong or is it a bug?

Here is the screen recording:

@ShariatPanah Can you check if it's the swipe angle that's causing the issue..

[ShariatPanah]

@AswinPG As I showed in the video, I'm performing an exact vertical angle to swipe, and I dont think it's similar to your issue, maybe at framework level yes

not repro with vs main build 32609.239.

[ShariatPanah]

were you able to repro this issue? i ask because you said "NOT REPRO" but you added verified tag to this issue
I'm confused :|

[ShariatPanah]

@ShariatPanah
Have you tried with this:
<Carousel {...} panGestureHandlerProps={{ activeOffsetX: [-10, 10], }} />

Reference: dohooo/react-native-reanimated-carousel#125

@Jun-FH we're on .net maui, this syntax is not a valid one in maui, but thanks for your help

[ShariatPanah]

which version? i tested with 8.0.40 and the issue is still there

[ShariatPanah]

also tested with nightly build version 8.0.60-ci.net8.24305.3 and still i'm facing the issue

[RhomGit]

I hooked up the OnCarouselViewScrolled event as described here: https://learn.microsoft.com/en-us/dotnet/maui/user-interface/controls/carouselview/scrolling?view=net-maui-8.0
The OnCarouselViewScrolled event doesn't ever seem to fire when vertically scrolling so yes, I am experiencing this issue also.

Thanks

i don't know who prioritize the issues, but this goddamn bug needs to be fixed, its almost 3 years since this bug has been reported. what are you working on if you can't fix something small like this?
