Hi Gary,
I'm sorry it is not clear for me. Do you mean filter funnel button or text filter?
Anyway in both cases it is shown automatically according to grid setting and it is not stored in the INI file.
Funnel buttons:
OptionsEx2.Filters.FunnelBtn = true
FieldsFilterButton - empty or list of fields with funnel button
Text filter:
OptionsEx2.Filters.TextBar = true
FieldsFilterButton - empty or list of fields with text filter
It is not shown for fields which do not support filtering (calculated field, graphic field etc.)
Regards
Tomas
