There are few causes when the navigational controls do not appear on the map. It is quite difficult to answer your question without your code (XAML and C#), but I can suppose the following:
First, please check the container you use for the map control. The RadMap control does not specify its default size when it is used inside a container like stack panel. But according to its content it uses specified value of the defined width or height of its container (standard behavior of MS MultiscaleImage control).
For example, in the case with vertical stack panel it gets specified value as a width and infinity as a height. When the control measured then it specifies its height from the width value.
As result when the browser window width is greater than height then the control has the height that greater than the visible height of the page. So, the navigation and zoom bar controls do not appear because they are in invisible area at the bottom of map.
In this case I would recommend you to specify a size of the RadMap control.
The map controls are not shown on the salesdashboard example because it just sets the UseDefaultLayout property of RadMap to "False".
All the best,
