>>>What happens if you access (or assign) a property for which you didn't write the code? Your example is exactly the best illustration of my objection: you have to write code to achieve default behavior. You access a property, you get its value returned. You assign it, it gets assigned the value passed. Why the know would you have to write code for that?

In VFP I would do a check for a form property and if it didn't exist, create it on the fly. I did that mostly because I had to share code with other developers and merge it. In most cases eventually the check never failed and the property existed when code got merged. It wasn't a longterm solution.

You can programmatically add controls to a form at runtime:

Properties though I don't know about. I know you can create types at runtime and types can have properties, but I don't think you can add a property to a type at runtime. Maybe you could inherit from it and add a property or something. Still, wouldn't it require reflection since the property wasn't known at compile time? How else could you access it?

This would be a good discussion in the net c# section where the net gurus would see it....
