You do not need that last line. The bizobj itself is the data source
for your controls.

Just set the DataSource for the controls (grid or anything else) to
the same string as the bizobj's DataSource. E.g.:
gridExhibitor.DataSource = "ModifyExhibitor"
Also, I might be reading too much into your names, but it looks like
you have different bizobjs for read and write operations. That is not
necessary and probably a bad idea. If you explain a bit what you're
trying to accomplish, we might be able to give you some guidance for
designing your tables and bizobjs.
