Is there any way that I can display a property in the PropertyGrid Control but not expose it when I pass the object to a dll?
 
You can have a property appear on the property grid that is not actually part of the class by using a custom TypeDescriptor (check out some tutorials on customizing the property grid), but what is the actual problem you're trying to solve here? There's likely a better solution.
 
Hi, sorry for the delay in replying.

What I've got is like a piping diagram. Each pipe is an object which I draw on the screen and each of these pipes contains a business object with a number of properties. I pass these business objects to dlls. The contents of each pipe can be sourced from a number of preceding pipes. The user can select that a pipe is used as a source for a secondary one. He has a choice between having whatever it contains passing through the secondary pipe or just a selected portion of what it contains passing through. At propertygrid level I want the source pipe to be shown as a line item. At dll level I want the actual contents that are passed through to be accessible.

So I was thinking of having a function for the benefit of the dlls which returns the pipe contents and a property for my benefit which holds details of the relevant pipes which is visible to the propertygrid but not through dlls.

Hope that makes it a bit clearer. What do you think?

I'm not sure exactly how you want it represented in the property grid, but a tutorial on customizing the property grid (like this) should have all the info you need. It's not simple, but it's doable.

Indeed, I'm not exactly sure how I want to represent this in the grid either, but that link looks helpful, thanks.
