The TUniDBFormattedNumberEdit component does not have a property where I can change the blankvalue.

Hi,

The TUniDBFormattedNumberEdit component does not have a property where I can change the blankvalue.

Calculations are wrong because it returns -1 if there is no value in the field.

How do I make the value 0, which is -1 in case of blankvalue, when there is no data?

When there is a blankvalue in the TUniDBFormattedNumberEdit component, it solves this problem by setting it to 0. What is the solution in DB component?

Is there a way to set the TUniDBFormattedNumberEdit blankvalue?

Hello,

Sorry, how can we reproduce this?

@Sherzod Hi

Add 1 TUniDBFormattedNumberEdit to the screen and connect any datasource.

The default value is 0. When you delete the 0 value, it becomes -1, so if there is no data on the screen, it becomes -1, I have to make it 0.

None of these solutions worked.

I just couldn't try this; There is no blur in the ExtEvents event of the TUniDBFormattedNumberEdit component, so I couldn't test it.

UniNumberEdit -> ClientEvents -> ExtEvents -> blur

I will try to check.

I couldn't reproduce your issue.

What properties did you change?

The example is attached.

Value should be 0 when there are no values.

I will check.

procedure TMainForm.edtTeklifYuzdeChangeValue(Sender: TObject);
begin
  //UniNumberEdit1.Value := edtTeklifYuzde.Value;
  if edtTeklifYuzde.Value < 0 then
    UniNumberEdit1.Value := 0
  else
    UniNumberEdit1.Value := edtTeklifYuzde.Value;
end;

Another solution:

1. 

procedure TMainForm.edtTeklifYuzdeChangeValue(Sender: TObject);
begin
  //UniNumberEdit1.Value := edtTeklifYuzde.Value;
  //if edtTeklifYuzde.Value < 0 then
  //  UniNumberEdit1.Value := 0
  //else
  //  UniNumberEdit1.Value := edtTeklifYuzde.Value;
end;

2. 

procedure TMainForm.edtTeklifYuzdeChange(Sender: TObject);
begin
  UniNumberEdit1.Value := edtTeklifYuzde.Value;
end;

3. 

procedure TMainForm.UniFormCreate(Sender: TObject);
begin
  FDMemTable1.Append;
  FDMemTable1.Edit;

  with TUniNumberEdit(edtTeklifYuzde) do
  begin
    BlankValue := 0;
    AllowBlank := True;
  end;
end;

Hi @Sherzod

I solved the problem with item 3. Thank you very much.

This error occurred because I couldn't make edtOfferYuzde.BlankValue := 0; These standards should be added to the component specifications. @Farshad Mohajeri
