I'm currently attempting to override the symbology for a layer from the ArcGISDynamicMapServiceLayer object from a local map service in ArcGisRuntime for .NET 10.2.6
The layer in the map package is defined as a SimpleMarkerSymbol type, and if I use another SimpleMarkerSymbol or a PictureMarkerSymbol I can override it with no problems.
However, what I really need is to override it with a TextSymbol. However, I'm coming up short on this. Whenever I try to do this, I get nothing, no symbol at all. All of the examples I've seen using TextSymbol only use a Graphics layer (which I really want to avoid due to the sheer amount of data), but none for service layers.
So, is this even possible? Can a TextSymbol be used to override the drawing for a layer from a local map service?
If it can't I suppose I could blit the TextSymbol to a PictureMarkerSymbol and use that, but it'd be nice if I didn't have to jump through those hoops.
