Hi All,

I've got a TIB_Combobox on a form with:
Style=csDropDownList
Items= Freshman (FR) ,Sophomore (SO), Junior (JR), Senior (SR)
ItemValues =1,2,3,4

Is it possible to allow user to enter NULL value for that field , and how to
search NULL and NOT NULL values?

I have the same problem with TIB_LookuComboBox?

Thanks for any help,
Djivo Milic
