For anyone who is interested, I now figured out the solution to my second question: How to change the values that display in a Combobox without changing the original data. In my case, I wanted to remove pipe characters ("|") from the viewable data. I put the following code in the RowSource_Assign method:

IF !"STRTR"$This.RowSource.and.!EMPTY(This.RowSource)
lcRS = ALLTRIM(This.RowSource)
This.RowSource = "STRTRAN(" + lcRS + ", '|')"
ENDIF
