Basemap Toggle

[SaqibAmin1]

With regard to the answer Dave gave on the following forum: http://gis.stackexchange.com/a/74170/124

How do I use a dynamic service in this solution?

I am trying to toggle the basemap with a dynamic service, or toggle 2 dynamic services, rather than a tiled basemap.

I aim to do to a dynamic service, what the following esri sample is doing to an arcgisonline map: https://developers.arcgis.com/javascript/jssamples/widget_toggle.html

Any ideas?
