I've noticed that when I'm setting up a combobox to be filled using a BO that I only have two columns to work with. The value column and the display column. Obviously the value column contains the ID and the display column can be a single field or a combination field. IE {1} or {1}{2}. I'm assuming I cant add any more columns to the combo box to hold related information about the items in the combo box.



If I am able to add more columns could you please instruct how to do so and then tell me how to access the information in these extra columns.



OR How would I query the datatable in the BO that contains the extra data. Keep in mind I'm piggybacking on a BO. Which is to say I'm executing Stored procedures to return records to fill combo boxes with.

Ok. So now I'm going to use a DevExpress LookUpEdit. I'm assuming I can't do the piggyback thing with the lookupedit. Right? Is there another way or do I need to create a dataadapter and a dataset to fill the lookupedit?

On a LookupEdit, you can set a business object as the DataSource.  Just remember to set the IsListSource property to True on the business object before you set it as the DataSource.  Then, yes, you will still be able to piggy back off of a business object.
