I was wondering if it is possible to label nodes (each with a distinct string labels e.g. A1, A2, A3, ... ) from a polyline and to only visually see the labels when a mouse hovers over a node? I'm working in C# .Net and was wondering if ArcGIS SDK supports this? Not sure if I have to override a built in class within the framework. Please, see the diagram below to get a visual representation of exactly what I would like to accomplish. Thank you guys!!
