UniDBComboBox now showing down arrow.

[skafy]

Hi,

 

I'm trying to create dbComboBox on the fly, but having a problem with proper display.

 

Here is my code. Also have FDConnection, FDQuery & DataSource all connected correctly

dbcombo:= TUniDBComboBox.Create(Self);
dbcombo.Align:= alTop;
dbcombo.AlignWithMargins:= True;

Now when I run the program there is Combobox without down arrow (where would I click to select a value from dropdown list). DBCombobox is presented as UniEdit. I'm missing drop arrow.

Hi,

 

DataSource -?

DataField -?

 

ReadOnly -?

 

Items -?

[skafy]

DataSource connected

DataField selected

ReadOnly - NO

Items sould get filled automaticly when query become active?

 

If I treat DBCombo as usual ComboBox and filled it staticly like so:

  dbcombo:= TUniDBComboBox.Create(Self);
  dbcombo.ReadOnly:= False;
  dbcombo.Enabled:= True;
  dbcombo.Items.Add('ad');
  dbcombo.Items.Add('aad');

I also don't see down arrow at the right site of the control.

No

[skafy]

No

 

Ok, So I've added records to DBComboBox like so:

  FDQuery1.Open;
  ShowMessage(FDQuery1.RecordCount.ToString);
  while not FDQuery1.Eof do
  begin
    UniDBComboBox1.Items.Add(FDQuery1.FieldByName('NAME').AsString);

    FDQuery1.Next;
  end;
  FDQuery1.Close;

ShowMessage print 35, whitch shows that query returned data.

 

Still no DownArrow at right site of the control.

Which build are you using?

 

Can you make a simple testcase for this?!

[skafy]

I'm using latest version 1.5 build 1479.

 

Here is an example. Button adds items to DBCombobox.Items

But where is the DataSet?

Did you manage to replicate the problem?

Sorry, at the moment, I do not have an installed FireBird server

I see. So could you please take the first example. DBCombobox is not connected in that case and filled with static data. the result is the same as when connected to DB,.

Just suggession, you don't need install firebird, use embedded firebird. ( https://www.firebirdsql.org/pdfmanual/html/ufb-cs-embedded.html )

https://firebirdsql.org/en/firebird-3-0/

download "zip" release and unzip it any folder your disk. So, via this way, you can use all version on same pc. just don't forget, this is work only local.
