In a Datagrid I have a column where I want to use a gdctLookupCombo as ControlType. I set the lookupsource, lookupfield and the displaycolumns. The field of the column is an id(int) and the Lookupfield is also an id(int). The displaycolumn is a textfield. When I ad a record in the grid and select a textvalue from the dropdown of the lookupcombo and save the data is shows the id-value instead of the textvalue of the displaycolumn. How can I fix it to show the textvalue in the column?
