Actually, the corresponding editor is passed to this event handler via the Sender parameter. So, please cast the Sender parameter to the corresponding type (to the TcxComboBox in this particular case) and then use its Properties.Items property to populate the editor's dropdown list:
procedure TForm1.cxVerticalGrid1EditorRow1EditPropertiesInitPopup(
Sender: TObject);
var
I: Integer;
begin
with TcxComboBox(Sender).Properties do
begin
BeginUpdate;
try
Items.Clear;
for I := 0 to 100 do
Items.Add('Item#' + IntToStr(I));
finally
EndUpdate;
end;
end;
end;
