When the custom ItemTemplate sets bigger value of its Height e.g. more than 44 pixels, the content of the UITreeViewCell is not sized correctly. Only the cell gets the correct value.

consider adding a "max height" and "max width" option so that the file sizes are manageable. So in that scenario if we set the max height to 450 then we shouldn't see anything larger than 800x450 in the result.

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.

<telerikBusyIndicator:RadBusyIndicator x:Name="radBusyIndicator"
                                               AnimationType="Animation4"
                                               IsBusy="{Binding IsBusy}"
                                               IsVisible="{Binding IsBusy}"
                                               Grid.RowSpan="3" />

When setting HorizontalItemSpacing or VerticalItemSpacing to the layout, the item spacing appears to be applied twice to the item. 
When setting BackgroundColor to the ItemStyle the background leaks beyond the boundaries of the item.

We should consider adding a mechanism to set a template for the appointments in Xamarin.Forms so that users can add additional elements to the appointments such as images, additional info, etc.

When using MvvmCross framework to load data when the View appears on the screen the ListView cannot be scrolled. It starts jumping rapidly instead.

Workaround:
Load the data in the constructor of the respective ViewModel instead inside its ViewAppearing() method.

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.

 

Best regards.
