TAdvDBComboBox.SelectItem not working?

Hello,

 
I am using a TAdvDBComboBox populated with some values. If I manually select any item, it does work properly when posting data. However if I want to set it to a predefined value by using TAdvDBComboBox.SelectItem which does show desired item but no data is posted.
 
How do I pre-select an item inside the TAdvDBComboBox control? tried ItemIndex, SelectItem but does not work.
 
Thanks.
