Is there some easy way to customize a ComboBox from Delphi to make the dropdown button with the arrow invisible? I mean without a lot of custom-draw code.. Maybe there is some control specific windows flag to set.
If I understand you correctly, you want all the functionality of the cxDBLookupComboBox, just not the button.
Try this in the FormCreate
:
cxDBLookupComboBox1.Properties.Buttons.Clear;
You can access other combo box buttons properties via non-published Buttons
property just like that.
