TDBAdvDetailControlDropDown

TDBAdvDetailControlDropDown can support display and stored value ? 

The field set via DataField is the field that is both displayed and stored.

If you want a control with a different displayed and stored value, you can use TAdvDBComboBox

bruno the component is different. i think TDBAdvDetailControlDropDown is more flexible. I have problem with items scrollbar that are small in a touch screen application. have you any idea to suggest to me ?

The standard Windows scrollbar width is used.For touch screen use, you might consider to globally change this: https://windowsreport.com/change-scrollbar-width-height-windows-8/ 


i also considered this ... is not a good thing!
