The map control should have the ability to disable the spring animation separately for panning without disabling zoom animation. This feature is implemented already for the WPF version of the RadMap control (you can use SpringAnimationsMode property). It seems quite difficult to implement the same for the Silverlight version. The difference between WPF and Silverlight is the MultiScaleImage control. In the WPF we use our own implementation of the MultiScaleImage , so we have a full control on its behavior. In the Silverlight we use standard control which does not provide similar functionality.
For better performance the dynamic layer should be able to request items after the panning / zooming is finished only. XAML team recently reviewed this request and decided not to address it in the future. Use the newer VisualizationLayer instead.
Add ability to change visibility of the information layer depends on the zoom range. DECLINED: Duplicate with http://feedback.telerik.com/Project/143/Feedback/Details/113252-map-support-maplayer-zoomrange-on-informationlayer
When a user clicks the center button on the separate navigation control (the standard buttons are collapsed) then a line appears at the center-bottom position. Reason for closing/ declining: The separate MapNavigationControl is designed to be used outside RadMap. The bug is only reproducible when the control is placed in the ItemsCollection of the RadMap which is not supported.
