locatebyattribute in c#

[Delfos, Jacob]

Please CC to the list if you reply, so you are more likely to get a
proper answer. 

I have no experience in C# whatsoever, but the approach that the
LocateByAttribute widget uses is that it saves each result into a
shapefile, and then adds the shapefile dynamically to the map (using
yellow outline). So you have to do something along those lines.

Regards,

Jacob
