[Linuxuser1234 1]

Im trying make a procedure that when you select an item from ComboEdit1 (it will officially list items from a ftp site) but for a test im 

trying to list the same item from ComboEdit1 to ComboEdit2 

procedure TForm4.ComboEdit1Click(Sender: TObject);
begin         

end;

i have tried %s like ComboEdit2.Items.Add('%S'); but that doesnt work

Do you want to add the selected from ComboEdit1 to the dropdown of ComboEdit2?

 

Hook Combo1Edit.OnSelect

procedure TForm4.ComboEdit1OnSelect(Sender: TObject);
begin         
  ComboEdit2.Items.Add(ComboEdit1.Text);
end;

This event is called when an item is selected from the dropped down list of ComboEdit1.
Naturally, you need to add code to see if the item has already been added before you add it.

Sure what:

procedure TForm1.ComboEdit1Change(Sender: TObject);
var
  i: integer;
begin
  i := ComboEdit2.Items.IndexOf(ComboEdit1.Items[ComboEdit1.ItemIndex]);
  if i = -1 then
    begin
      ComboEdit2.Items.Add(ComboEdit1.Items[ComboEdit1.ItemIndex]);
      ComboEdit2.ItemIndex := ComboEdit2.Count - 1;
    end
  else
      ComboEdit2.ItemIndex := i;
end;


//---
procedure TForm1.ComboBox1Click(Sender: TObject);
 if (ComboBox2.Items.IndexOf(ComboBox1.Items[ComboBox1.ItemIndex]) = -1) then
 begin
    ComboBox2.Items.Add(ComboBox1.Items[ComboBox1.ItemIndex]);
    ComboBox2.ItemIndex := ComboBox2.GetCount-1
 end;
//

procedure TForm1.ListBox1Click(Sender: TObject);
begin
  if (ListBox2.Items.IndexOf(ListBox1.Items[ListBox1.ItemIndex]) = -1) then
    ListBox2.Items.Add(ListBox1.Items[ListBox1.ItemIndex]);
end;

@programmerdelphi2ki get this error TComboEdit does not contain GetCound and yes i have tried var

TComboBox is VCL and use "GetCount" or you can use "ComboBox1.Items.Count"

TComboEdit is FMX  (your project is FMX then... ) and use "Count" or "ComboEdit1.Items.Count"

 

NOTE: ComboEdit ONCLICK = click on component (into edit control from it), not on "Items"

that way it's better:

procedure TForm1.ComboEdit1Change(Sender: TObject);
var
  i: integer;
begin
  i := ComboEdit2.Items.IndexOf(ComboEdit1.Items[ComboEdit1.ItemIndex]);
  if i = -1 then
    i := ComboEdit2.Items.Add(ComboEdit1.Items[ComboEdit1.ItemIndex]);
  //
  ComboEdit2.ItemIndex := i;
end;

NOTE 2: you are ADD value in same ComboEdit2... with ComboEdit2 ???

[Lars Fosdal 1877]

Well, I should also pay better attention to details.  My initial reply was VCL code, not an FMX code.

My apologies.

 

TComboEdit.OnChange handler

procedure TForm2.ComboEdit1Change(Sender: TObject);
begin
  if ComboEdit2.Items.IndexOf(ComboEdit1.Text) < 0
   then ComboEdit2.Items.Add(ComboEdit1.Text);

  ComboEdit2.ItemIndex := ComboEdit2.Items.IndexOf(ComboEdit1.Text);
end;
