I have a RadPieChart in my application. When removing the app from the backstack and service is running, then opening the app from the notification, the app crashes with:
Java.Lang.IllegalStateException: ChildNode is already parented by a ChartElement instance.
Legend is not fully visualized, the square color is missing, only the text is displayed.
on iOS it seems the issue happens only on simulator, on iPhone device SE 2022 the legend is fully displayed
Series labels are not properly rotated with LabelFitMode set to "Rotate".
On iOS it seems the issue happens only on simulator, on iPhone device the labels are aligned (rotated) as expected.
Android.Views.WindowManagerBadTokenException: 'Unable to add window -- token null is not valid; is your activity running?'
When adding a plot band annotation to the date time axis, it is not applied on MacCatalyst and iOS. In addition if using binding, an exception is thrown.
System.ArgumentNullException: Value cannot be null.Parameter name: minimum
at TelerikUI.TKRange..ctor (Foundation.NSObject minimum, Foundation.NSObject maximum)
It works on Android and WinUI
An exception is thrown when setting the ChartPallete FillColor property. The issue is reproduced on all platforms.
Workaround:
Also set the StrokeColor property.
<telerik:ChartPalette>
<telerik:ChartPalette.Entries>
<telerik:PaletteEntry FillColor="Red" StrokeColor ="Yellow"/>
<telerik:PaletteEntry FillColor="Gray" StrokeColor ="Yellow" />
<telerik:PaletteEntry FillColor="Blue" StrokeColor ="Yellow"/>
</telerik:ChartPalette.Entries>
</telerik:ChartPalette>
Workaround:
Change the Palette.
ChartPalette chartPalette = new ChartPalette();
chartPalette.Entries.Add(new PaletteEntry { FillColor = Colors.LightBlue, StrokeColor = Colors.LightGreen });
this.chart.Palette = chartPalette;
