Would like an alternative date picker.  This would allow you to choose a date from a monthly calendar instead of scrolling month, date, or year.  It would be similar to the web version.

There seems to be 2 issues with Telerik ui for xamarin and Xamarin.AndroidX.Core versions 1.3.2.2 and newer where A) Linker seems to be failing when set to "Sdk Assemblies Only" on Visual Studio 16.9.0.

 

The other issue is with Telerik RadListView and same  AndroidX.Core at runtime I am getting the following exception:

System.TypeLoadException: 'VTable setup of type Telerik.XamarinForms.DataControlsRenderer.Android.ListViewAccessibilityDelegateCompat failed'

 

Please advise

Duplicated

add PivotGrid control. UI for WPF has this control: https://docs.telerik.com/devtools/wpf/controls/radpivotgrid/overview

Appointments in MonthView can be shown inside day cells as shapes or as text (with and without shape) - this is controlled by DisplayMode  property of the AppointmentsStyle.

Currently, when using Text DisplayMode there is an additional label indicating the amount of the appointments for a certain day that remain hidden (due to not enough space).  We should provide some kind of indication in case of Shape DisplayMode that there are more appointments inside the day cell.

When an appointment is longer than 1 day and it has a recurrence rule -> you see the appointment in the first day of the range only. 
It is reproducible in all view modes except the Agenda. Check week mode, multi day etc.

We are attempting to use the chart's CartesianPlotBandAnnotation to highlight a section of a graph on a DateTimeContinuousAxis.  This works well on Android, but in our code it produces an exception on iOS (stack trace below).

I attempted to reproduce the problem with the SDKBrowser solution.  I converted the PlotBandAnnotationsCSharp to use a DateTimeContinuousAxis on the horizontal axis, and TemporalData for the ViewModel. When I try to run this on an iOS simulator, it doesn't even navigate to the page; maybe an exception is being thrown and caught that I can't see.

I'm attaching the revised SDKBrowser solution, and including the stack trace from our app (below).

Hi telerik team,

I know, my case is very specific, but I got this Bug and need to fix it somehow.

About: I have a RadSideDrawer in which I have a Collection View in which Header I have a Carousel View. When I rotate the phone in landscape mode the items are resized. After rotate back to portrait they are resized, but a lot of space appeare between them. So the layout is somekind wrong calculated. 
This only occure in this combination on iOS. If I remove the RadSideDrawer it works, if I remove the Collection View it also works, but both together not.

Reprosteps: Create a view with carousel embedded into the header of collection view embedded in to RadSideDrawer. (see attachment)
Rotate to landscape, rotate back to portrait mode.

System information:
iOS
xamarin: 5.0.0.2012
xamarin telerik ui: 2021.1.119.4

If you have a workarround for me, I will be very happy. Somehow to trigger a recalculation might help. I tryed set some InvalidateMeasure and ForceLayout but it didn't help. Either it don't work ot I apply it wrong. 
Any help is welcome!

Best regards,
Niko

I'd like a little advice and suggest a new control.

Prior to iOS14 we used https://github.com/jamesmontemagno/MediaPlugin as our media picker in our Xamarin forms app.

Since https://github.com/jamesmontemagno/MediaPlugin does not work on iOS14 and is not being actively developed, we switched to xamarin/Essentials and now face a rotation issue (https://github.com/xamarin/Essentials/issues/1514) for a long time.

There seems not to be any alternatives!

Hi,

I had developed an Xamarin application, in a modal I open a PdfViewer.

PdfViewerPage pdfViewer = new PdfViewerPage(item.IdAllegato, item.Path, item.FlagScaricabile);

Navigation.PushModalAsync(pdfViewer);

I assign a url to the PdfViewer source.

pdfViewer.Source = new Uri(uri);
Everything is fine in debug mode but when I publish the app on android the PdfViewer show "an error occurred while loading the document" with all pdf.
