DynamicMapServiceLayer added through code not recognized by button.

Please bear with the low level this question is probably at. I am new to the Runtime and wpf xaml.  I
believe my question is more wpf/xaml based one. I hope my description that follows is clear enough.


I have developed a prototype app attempting to emulate the mvvm pattern.  Between looking at the
toolkit samples and the regular runtime samples, I have implemented a 'toggle visible layer' method in my MapViewModel.cs that is successfully bound to a button on my MainWindow.xaml.  This button is handling a feature layer that I add to the application through app.xaml.  This is working well. I am able to toggle the layer's visibility through the button.


I want to add another button to handle another layer and leverage the same toggle visible method. I have added the button in MainWindow.xaml and set up the same binding parameters, except of course using the correct layer name. However, the additional layer that I wish to ‘toggle’ is added through code in the MapViewModel as a DynamicMapService Layer from a map package.


The layer I am interested in is successfully added to the map  However, the button that I have added to toggle the visibility for this layer is never enabled. I incorrectly assumed that this button would come to life when the layer is added to the map.  No such luck.


Is it possible to associate a control with command method using a layer that is added through code as the parameter?

What would be the correct approach to handling this situation?


Any insight would be appreciated.
