Hi everyone,

I'm running into an issue with the Telerik PDF Viewer in a .NET MAUI project.

Environment:

• Telerik.UI.for.Maui: 11.1.0

• .NET MAUI: 9.0.111

• .NET version: net9.0-ios

• Platform: iOS

Problem:
Scrolling inside the RadPdfViewer does not work on iOS. The same code works as expected on Android — I can scroll through the PDF content normally. On iOS, the viewer loads and displays the first page correctly, but it’s completely static: no vertical scroll or swipe works. However, navigation using PdfViewerNavigateToNextPageToolbarItem or PdfViewerNavigateToPreviousPageToolbarItem still functions as expected.

<ContentPage>
    <Grid RowDefinitions="Auto, *">
        <telerik:RadPdfViewerToolbar x:Name="pdfViewerToolbar"
                                     OverflowMode="Scroll"
                                     PdfViewer="{x:Reference pdfViewer}">
            <telerik:PdfViewerFitToWidthToolbarItem />
            <telerik:PdfViewerNavigateToPreviousPageToolbarItem />
            <telerik:PdfViewerNavigateToNextPageToolbarItem />
            <telerik:PdfViewerZoomInToolbarItem />
            <telerik:PdfViewerZoomOutToolbarItem />
            <telerik:PdfViewerSearchNavigationToolbarItem />
            <telerik:PdfViewerToggleLayoutModeToolbarItem />
        </telerik:RadPdfViewerToolbar>
        <telerik:RadPdfViewer x:Name="pdfViewer"
                              Grid.Row="1"
                              AutomationId="pdfViewer"
                              BackgroundColor="{StaticResource White}"
                              IgnoreSafeArea="False"
                              IsClippedToBounds="True"                              
                              LayoutMode="ContinuousScroll"
                              Source="{Binding PdfFile}" />
    </Grid>
</ContentPage>

Has anyone else encountered this issue, or is there a known workaround/fix for iOS?

Thanks in advance!

When clicking the month dropdown and opening the month view,
there are those grey days (prev\next month days), clicking them sometimes shift the whole month to the new month (previous or next one) and sometimes it doesnt... maybe its about the line, im not completely sure whats the rule for this.

Its unclear.

Notice the 'arrows' are left aligned. How can I center these (I am working on a custom control based on NumericInput). I also want to center the numeric text.

Thanks.

Hello. Would be interested in migration .NET MAUI Scheduler from Xamarin with the following UI:

1. Selectable days and days with more customizable styles, like height etc.

2. Appointments indicators in days views

Everything achieved in xamarin using RadCalendar

Already checked Scheduler WeekHeader and Slot in UI for .NET MAUI | Telerik Forums

Thanks.

Would like to add long tap handler for the item view of RadCollectionView.

Adding long tap effect breaks SelectionChanged functionality. Both gestures (long and single tap) added seems does not working.

Probably any in-box solution possible? 

Hello,

Could someone explain to me how to make on-demand loading, searching, sorting, and filtering work well together?

Note that I use MVVM in my application.

Thanks!
