Hi All,
Created an issue in the past but got no answer. Now attached a better example project. Please try and comment. Is it a Qt bug or this is the expected behaviour?

I don't use db controls at all so don't know what's exact problem. Can it be reproduced with regular TComboBox ? I cannot understand what's exact problem from issue explanation ...
1.TCombobox is empty
2.You are assigning items
3.ItemIndex should stay -1 instead of 0 (first item selected ? ) 4.What about other widgetsets ?

Attached a screenshot to the issue. My problem is with Qt widgetset... If append a record into an empty dataset in FormShow the new record selected automatically in the DBLookupComboBox.

Yes I got same result with a TComboBox. See the attached screenshot, better than my description.
1.TCombobox is empty
Yes.
2.You are assigning items
Yes, in two places. In FormCreate and in FormShow.
3.ItemIndex should stay -1 instead of 0 (first item selected ? )
No automatic selection if Items filled up in FormCreate but automatic selection if filled up in FormShow.
4.What about other widgetsets ?
On Windows works as expected. Nothing selected. (Got same result with Delphi.)

Ok, then please create example project with TComboBox - it's easier to fix it then.

No automatic selection if Items filled up in FormCreate but automatic
selection if filled up in FormShow.
I see, in FormShow TComboBox handle is created, so something happening at WS part.

Ok, just create example project with TComboBox which reproduces problem so I'll sit with it and try to fix it somehow.
