Currently the first label marking the DayStartTime is not visualized in the timeline of the DayView (and MultiDayView) on Android. This leads to inconsistency with iOS, where the first label is displayed.

Images that have drop shadow effect are not properly rendered in PdfViewer - black background appears instead.

Placing a StackLayout inside the GroupHeaderTemplate causes a NullReferenceException at Xamarin.Forms.StackLayout.AlignOffAxis method

If you define a PropertyGroupDescriptor in XAML or in page constructor and the PropertyName is set to a nested property, the grouping is not applied.

Grouping by a nested property works correctly when called from the Filtering UI or on a button click action.

If the ItemsSource of RadChat is bound to an ObservableCollection of chat items and the control is not visible, adding items to that collection crashes the app with the following: 

Foundation.MonoTouchException: Objective-C exception thrown.  Name: NSInternalInconsistencyException Reason: attempt to insert row 0 into section 0, but there are only 0 rows in section 0 after the update

Hello,

 

RadPopup control causes memory leaks on iOS.

Here is the repro project https://github.com/VitalyKnyazev/RadPopupLeak

If you clear the collection bound to the series ItemsSource and add new items to it, the changes are not reflected on the Chart

If customers try to load struct or readonly struct into the TreeView, the items does not get displayed.

We are having trouble getting the RadExpander to respect the Corner Radius property. When using the CornerRadius with the IsClippedToBounds set to true, the header's Background Color still spills over. refer to the attached image.

Follow this tutorial https://docs.telerik.com/devtools/xamarin/controls/listview/listview-features-load-on-demand#loading-mode-with-collection 

It works on Android and iOS, but on UWP it is defaulting to Explicit mode and clicking the load button crashes the app.

Hello,

 

As per forum thread https://www.telerik.com/forums/autocompleteview-causes-memory-leaks ACV control causes memory leaks on iOS.

Here is the repro project https://github.com/VitalyKnyazev/AutoCompleteViewLeak

When RadListView is setup to load its items on demand and the LayoutDefinition is GridLayout with SpanCount set to 2 or more, the Footer Template does not take all the width, it expands only to the Width of the first column.

when showing 3 months (last month, present month and the next month) on calendar component, the next month tab is displayed twice. see the attached video

Above the TreeView there is a Telerik.SegmentedControl, with two segments. If I click on one of the segments the ItemsSource of the TreeView gets updated by using .Add() or Remove() of the ObservableCollection.

If every Segment is called for the first time there is no problem. But if I want to clear all Items and display the empty treeView I get the following Exception.
Java.Lang.IndexOutOfBoundsException: 'Inconsistency detected. Invalid item position 0(offset:-1).state:14 md5a5af569a83c1a3f5c3a8a63bd7d39860.RadExtendedListView{c6376f1 VFED..... ........ 0,0-1200,840 #5}, adapter:com.telerik.widget.list.ListViewWrapperAdapter@b30041b, layout:android.support.v7.widget.LinearLayoutManager@3fd42d6, context:md5db22775bb305bf9756607f4261793d51.MainActivity@1d6cd4f

The bug can be reproduced on iOS 13 only. It is not reproducible on earlier versions of iOS. Run the attached project on iOS 13 device or Simulator to reproduce it.

Sometimes when focusing an entry and the onscreen keyboard shows up, the ListView is not scrolled correctly, so the entry is overlapped by the keyboard. The ListView layout appears messed up after that and the scrolling does not behave correctly.

When longer string is used for HeaderText the text could not be wrapped. Also the issue occurs when using Label with LineBreakMode="WordWrap" inside the TabViewHeaderItem.Content:

<telerikPrimitives:TabViewItem>
    <telerikPrimitives:TabViewItem.Header>
        <telerikPrimitives:TabViewHeaderItem>
            <telerikPrimitives:TabViewHeaderItem.Content>
                <Label Text="Lorem ipsum dolor sit amet, consectetur adttert etertert erterter ipiscing elit." LineBreakMode="WordWrap"/>
            </telerikPrimitives:TabViewHeaderItem.Content>
        </telerikPrimitives:TabViewHeaderItem>
    </telerikPrimitives:TabViewItem.Header>
    <telerikPrimitives:TabViewItem.Content>
        <Label Margin="10" Text="Label" />
    </telerikPrimitives:TabViewItem.Content>
</telerikPrimitives:TabViewItem>

 

As of the latest release (10/04/2019) RadPieChart with a PieSeries having LabelBinding set to a property name, and ShowLabels set to True, with the list of data bound to ItemsSource containing one or more empty pie slices (a null in the list), causes a System.Reflection.TargetException to be thrown on load of the page containing the chart in iOS (this scenario works fine in UWP).

I am using the latest available Visual Studio 2019 (16.3.5) and the latest available Xamarin.Forms package (4.2.0.848062) and testing on an iPad with iOS 13.1.  The reason I need to have a null value in the list is so that the custom color palette I'm applying will always apply the same colors to the same data points (pie slices), even though in some cases, zero or one or two of the three pie slices will have no data value (and so should not appear in the chart, but still "use up" the corresponding color in the 3 colors of the palette).

In the 08/02/2019 release, this scenario worked fine in iOS (the 09/13/2019 release had the https://feedback.telerik.com/xamarin/1431067-chart-ios-invalidcastexception-is-thrown-when-the-chart-is-loaded issue, which is now resolved in the 10/04/2019 release, but which prevented my testing in iOS since in my app I had RadCartesianCharts on the same pages as the RadPieCharts).

The newly broken functionality in iOS could possibly be related to two other items that are marked completed:
https://feedback.telerik.com/xamarin/1366403-piechart-tooltip-behavior-is-not-working-properly (in 10/04/2019 release)
https://feedback.telerik.com/xamarin/1365842-chart-null-value-support (in R3 2018 SP release)

When the series data is updated and axis labels are redrawn, occasionally the default DateTime format is shown in DateTimeContinuousAxis.

Column names in column selector are not visible in Android the first time the column selector is shown. This happens only in the case UserFilterMode is disabled. 

I've attached a handler to the ViewChanged event of the Calendar component.

The event fires on Android but not on UWP. I've tried changing the view type using the calendar controls and also programatically but the event is not being fired.
