Scrolling not working correctly

[Tomas Turek]

Hi, I am using pdfviewer to view pdf document but I have a problem with scrolling on both (android, iOS) devices.

If I use simulators I am able to start scrolling only on top of the screen (as attached picture) or with right slider.

If I use a real device (Android 9 or ios 10.3) with EnableScrollHead="True" I can scroll only on top of the screen (as attached picture) or scrolling with right slider.

If I use a real device with EnableScrollHead="Flase" everything is fine on android, but completely not working on iOS. A right slider is missing.

Hi Tomas, 

 

Greetings from Syncfusion. 

 

On analyzing your sample, you are placing PDF viewer inside Stack Layout. So that it will not allow the user to scroll the PDF document until we zoom the PDF viewer control. We need to set the VerticalOptions and HorizontalOptions for the scrollable children to properly layout inside the StackLayout for Xamarin.Forms. We have ensured the same behaviour with Xamarin.Forms WebView which is a scrollable view. Please use the below code example to get this issue resolved.   

 

Code Example:  

<StackLayout Spacing="0"> 

            <syncfusion:SfPdfViewer x:Name="PdfViewerControl" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand" BookmarkNavigationEnabled="False" EnableScrollHead="False" /> 

</StackLayout>  

 

Could you please try the above modified sample and let us know whether the above proposed solution meets your requirement?
