SfListView ScrollBar vertical not showing

[lionel felix]

I am using SfList view, but the vertical scrollBar does not show, and I set IsScrollBarVisible to true it does not work either, nor do I see the vertical scrollBar visible in the examples that contains syncfusion, how can I enable the vertical ScrollBar to be visible? I have updated the nuget SfListView package (18.1.0.52)

thanks for your help.

Hi Lionel, 

Thank you for using Syncfusion products. 

We have checked the reported query “SfListView ScrollBar vertical not showing” from our end. We would like to let you know that ScrollBar will be visible only on scrolling to indicate the position of ListView. If ListView height is less than device screen height, ScrollBar will not be visible, it is the behaviour of ListView. Default value of IsScrollBarVisible is True. 

You can also refer to the following user guidance document for the same from the following link, 

UG link: https://help.syncfusion.com/xamarin/listview/scrolling#scrollbar-visibility 

Please let us know if you need further assistance.

Thanks for your answer, but I have a list with several elements that allow me to move it, but at no time does the scrollbar appear, I tried with ListView of xamarin forms and the scrollbar if it appears, but not with SfListView, Something I noticed is that in the syncfusion examples it doesn't appear either, it only appears in the list in horizontal mode.

Thank you for your answer, I actually tried your project and if the scroll bar is displayed, then I realized that the version of xamarin forms that was provided in the project is: xamarin forms 4.5.0.617, and the version that I am using of xamarin forms is 4.6.0.800, by downgrading from xamarin forms I was able to solve that problem. my conclusion is that in the latest version of xamarin forms (4.6.0.800) that is currently available, the scrollbar display does not work. I could check it by updating xamarin forms in the project that was sent to me and I had the scrollBar visibility problem again.

scrollBar visibility in xamarin forms 4.5.0.617 is Ok,

scrollBar visibility in xamarin forms 4.6.0.800(Lasted version) not working.

Hi Lionel, 

Thank you for the update. 

We are able to replicate the reported issue in Xamarin.Forms 4.6.0.800. We would like to inform you that we have used Xamarin.Forms ScrollView for ListView scrolling purpose. We have checked a simple sample using ScrollView and we are able to replicate the issue in Xamarin.Forms (4.6.0.800). The reported issue is a framework issue and we have logged the bug report for the same. Kindly refer the following report for further reference from below for further updates.
