Using the code code below, the RadBusyIndicator will animate the first time you toggle IsBusy.

However, any subsequent changes to IsBusy will show the AnimationType's graphic, but without animation.

When RadCalendar is inside Xamarin Forms Tabbed Page. Switching between tabs triggers Calendar SelectionChanged and the calendar DisplayDate is changed. 

Workaround:
the issue could not be reproduced when RadTabView is used and its IsContentPreserved property is set to true.

I have tried to change the cell background color programatically .

This is Perfectly Working on Android Devices.

But,this not working on iOS devices.

Please provide better solution to solve this issue.

below i have attached the xmal and .cs file

Provide an Auto option for the SuggestionViewHeight that would dynamically change depending on the content.

My xaml code,

<telerikControls:RadCheckBox IsChecked="{Binding IsSelected, Mode=TwoWay}" HorizontalOptions="Center" VerticalOptions="Center" />

My model class code,

private bool _isSelected;
        public bool IsSelected
        {
            get { return _isSelected; }
            set
            {
                _isSelected = value;
            }
        } 

Version information,

Xmarin form version : 4.1.0

Telerik UI version : 2019.2.802.1

iOS version 12.2

Dear,
It would be interesting if the map control could read a shapefile or kml file and visualize the shapes, besides exporting the modifications of the map (shapes) to a shp format.
