Is it possible in the ArcGIS .NET SDK to allow one graphic over layer have different labels background colors for different graphics on the same layer?
I couldn't figure out how to have different label background color of the labels depending upon a value of the graphic.
Adding a text symbol with different background derived from an attribute is currently not supported but is on our list of future candidates. If it were a handful of symbols you could override symbol for those graphic. But I am sure it is not the case.
I will add your use case to our backlog issue and would appreciate if you could you please share your requirement and specific workflow with as much details as possible. An elaborate workflow adds more some weight to the feature and help us prioritize it.
