SfRotator in ScrollView allows vertical scrolling on iOS

we are seeing an unpleasant behavior of SfRotator in a XF-ScrollView under iOS since SyncFusion

If you grab the rotator to scroll it horizontally, you are also able to scroll the whole page vertically.

This was neither the case with versions and prior, nor is it the case on Android - even with current versions.

Likewise the vertically scrolling is inhibited if you have a horizontally oriented SfListView within a ScrollView.

Hence, we consider this not as intentional feature.

We used the following code snippet (MainPage.xaml) within a fresh XF project (created on Visual Studio 2019 for Mac). We tried XF 3.6 and XF 4.0, which made no difference.

<ContentPage x:Class="App.MainPage"
            <StackLayout Spacing="0">

                <syncfusion:SfRotator x:Name="rotator">

                                <BoxView Color="Red" />

                                <BoxView Color="Green" />

                                <BoxView Color="Blue" />


                <BoxView Color="Yellow" HeightRequest="1000" />


This is the behavior since

This is the (for us desired) behavior on Android and prior iOS versions.

How does one avoid this?

Hi Ulrich,

We have fixed the reported issue of "Rotator allows vertical scrolling of parent while rotator item is moved". The fix will be available in our 2019 volume 2 release, which will be available on first week of July 2019.

We appreciate your patience until then.

Hi Muneesh Kumar G.,

thank you very much for addressing this in Syncfusion 17.2.

Unfortunately we are still seeing in a different behavior between a horizontal SfListView and the SfRotator.

With SfListView the "other" scroll direction is locked as soon as you scroll in one direction. With SfRotator one could still first scroll vertically and then nevertheless scroll horizontally the rotator.

We would prefer the SfListView behavior for SfRotator too. Do you think, this is possible?

Thank you very much

It seems the issue has been parially resolved.

If I start to scroll horizontally vertical scrolling is locked.

But if I start scrolling vertically I the can scroll in both directions.

Will you fix this as well?

Hi Ulrich, 
Thanks for your update. 
We have checked reported issue at our end. But we would like to inform you that when we scroll vertically then hold with scroll the rotator horizontally, the rotator not moved in horizontally. Same happens in reverse action. We have recorded video for this and attached in below location please find video from below location. 
Please let us know if you have any concern.
