Dynamic Property in C#.net

From the context I understand by typing "Dynamic properties" you mean "controls created at runtime".

If that's the case, then I would create a bunch of business objects that represent the data behind those controls (Images for picture boxes, Strings for labels, Enumerations for group boxes or whatever suits your needs).

Then clicking on a picture box would cause some object to react in a way you define. That could include changing some other controls or sending messages to other objects that in turn react in changing some controls.

Generally, it's hard to tell in detail. At least without knowing your needs.
