I dropped a TUpDown named UpDown1 component onto a form and associated it to a TPanel named Panel1. I thought that once I associated UpDown1 to Panel1 that when the user clicks on the up or down arrows the value displayed in Panel1.Caption would automatically be updated to the correct value. I realize that UpDown1.Property contains the current value, but I thought the association would update Panel1.Caption. The end result is that it doesn't. What do I need to do to get the Panel1.Caption to show the correct value. I have inserted no code into any of UpDown1's methods. When the user clicks on the arrows nothing happens.

Don't associate it with UPDown (there may be a bug in the VCL). It will work if you don't. Try this code:

procedure TForm1.UpDown1Click(Sender: TObject; Button: TUDBtnType);
begin
Panel1.caption :=Inttostr(UpDown1.position);

end;

Thanks for the answer. I original used a TLabel to show the count, but since you cannot associate it with the TUpDown I decided use the TPanel instead. Guess I should of just left the the things the way they were.
