How to view .NET objectColletions in CR2008 designer? (not through vs2008)

Hi

I have a report where i use TTX-files (field definition files) as datasource of my subreports.

In .NET I created classes that look exactly the same as those ttx-files.

I bind them together in code. And the report works great!

My true question is: How can I easily view a .NET object, or an object-collection in the crystal reports 2008 designer?

Working with the ttx files is very hard to maintain and time-consuming.

When the class updates, the report's ttx-files get outdated and I can't just sync them.

A solution would be that I could select a .net class (the file, or through a dataprovider) though the designer application (cr2008). But I haven't figured out how,

Does the feature exist? Please give me some guidance 😉

Greets,

Wim
