I have a dataset that already has relations between two of it's tables.

Ultimately I want to set this to a WebExplorerBar so the bars are the header and I put some relation/nested data inside using the relations I've setup.

Do I have to go through the WebHierarchicalDataSource to do this? 

I'm looking for some help on how to do this all in the code behind?  I have my dataset with relations setup already.  How do I get it assigned to the WebExplorerBar?

Thanks!
