Handling TDateTimePicker events
Hi,
How can I know when the user presses the escape key, or clicks outside of the control, to close a TDateTimePicker?
I've tried using Keydown to trap the escape key, but can't get it to work.
Regards,
Bill

do you want to know if he picked the date? or just if the user has canceled?

I need to know if the user cancelled, either because he pressed escape or clicked somewhere else.

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
So do like this
var
PreviousDateTime: TDateTime;
procedure TForm1.DateTimePicker1Clos
begin
if DateTimePicker1.DateTime = PreviousDateTime then
begin
Memo1.lines.Add('cancelled
end;
end;
procedure TForm1.DateTimePicker1Drop
begin
PreviousDateTime := DateTimePicker1.DateTime;
end;
var
PreviousDateTime: TDateTime;
procedure TForm1.DateTimePicker1Clos
begin
if DateTimePicker1.DateTime = PreviousDateTime then
begin
Memo1.lines.Add('cancelled
end;
end;
procedure TForm1.DateTimePicker1Drop
begin
PreviousDateTime := DateTimePicker1.DateTime;
end;

Balshe,
I was thinking of some sort of event driven solution, but I think I can use what you suggest.
Thanks,
Bill

Balshe's solution works only once.
Strange You accept it.

It's the concept of simply checking if the date changed, not the actual implementation, that I accepted as a solution.
procedure TForm1.DateTimePicker1Clos
begin
// do whatever
end;
