Default value on a dblookupCombobox when dataset is in insert mode

[franzandreani]

Hi all

In delphi when i want to display a default value in a dblookupcombobox i do something like this

if datasouce.state = [dsInsert] then begin

   DBLookupComboBox1.ListSource.DataSet.Locate('id', '3', []);
   DBLookupComboBox1.ListSource.DataSet.FieldByName(DBLookupComboBox1.KeyField).Value;
   DBLookupComboBox1.keyvalue:=DBLookupComboBox1.listsource.dataset.fieldbyname(DBLookupComboBox1.keyfield).value
end;

but in uniGUI it does not shows point to the id i have selected as a default. 

Any Idea?

thank's a lot

Thank you Sherzod , no in grid editor - i heaven't not yet afford this opportunity, i have a form with a dblookupcombobox and i would like to give it a default value.

Your case is not very clear to me. Can you give an example then, possibly on VCL?

Hi Sherzod

making the test application for you I found that it works as expected - in the test app - so the code above works well. I have to find the reason why in the real application it does not work.

thank you for you support
