Does someone have a code snippet showing how I can display a field value from the 
TDBGrid row where the mouse pointer has stayed long enough to invoke the hint?

Answer:

This is the way I would do it:

1   { ... }
2   if not VarIsNull(table1['PARTNO']) then
3     dbGrid1.hint := table1['PARTNO'];


I found that you have to check to see if there is data in the field before you use it, also you would need to convert to a string inttostr(table1['PARTNO']) if needed.
