Null exception on loaded

[Milos Kajtez]

I have a page with chart and rotator. Chart can be enlarged so I need to hide rotator. 

I do this by controlling height of rows, setting chart row to Auto and rotator to 0. This works if both are shown on start, and switching views work fine. 

If start page has no rotator, row height is 0, I get 

System.NullReferenceException: Object reference not set to an instance of an object.

   at Syncfusion.UI.Xaml.Rotator.SfRotator.SfRotator_Loaded(Object sender, RoutedEventArgs e)

Any way around this?
