I want to place a combo-box in a cell of a grid displaying
values of another table. It was no problem to place the
combo-box in the cell - but it doesn't show the desired data
and it behaves quite strange, if I change the value of
one row. My master-table contains a keyvalue (person.vereinlfdnr)
and the child-table uses this as primary-key (verein.lfdnr). Now
I want to display the value of verein.bezeichnung in the combo-box
(depending on the values in person.vereinlfdnr) and want to be
able to change this values for every person. Any idea how to do this ?
