Dear All
Hi,
I have an edit component but I don't want to let user type alphabet in it.it
should be filled by numbers only,how can I prevent from typing alphabets in this
edit.

Handle the KeyPress event with something like:

if key not in ('0'..'9', #8 , #9  )
  then key := #0;

Sorry I didn't realise that this is was a WinForms question.
The code should be:
 if e.KeyChar not in ('0'..'9', #8 , #9  )
   then e.Handled := true;
