Try this

http://delphi.about.com/cs/adptips1999/a/bltip0799_2.htm

Add the following code to the OnKeyPress event for the Edit1 component:

~~~~~~~~~~~~~~~~~~~~~~~~~
with Sender as TEdit do
    if (SelStart = 0) or 
       (Text[SelStart] = ' ') then
          if Key in ['a'..'z'] then 
             Key := UpCase(Key) ;

In case you want to capitalize when pasting from clipboard as well as when typing then you can use OnChange event of the TEdit:
procedure TForm1.Edit1Change(Sender: TObject);
var
  i:integer;
begin
   i := Edit1.SelStart;
  if (Edit1.Text <> '') and(Edit1.Text[1] in ['a'..'z']) then
    begin
      Edit1.Text := StringReplace(Edit1.Text, Edit1.Text[1], UpperCase(Edit1.Text[1]), []);
       Edit1.SelStart := i;
    end;
end;

And if you want to keep the first char only capital even if the cursor has been placed at the beginning of the text and a new char was entered then the previously capitalized char would be lowered, then:
procedure TForm1.Edit1Change(Sender: TObject);
var
  i:integer;
begin
    if (Length(Edit1.Text) > 1) and ((Edit1.SelStart = 1)) and(Edit1.Text[2] in ['A'..'Z'])  then
      begin
        Edit1.Text := StringReplace(Edit1.Text, Edit1.Text[2], LowerCase(Edit1.Text[2]), []);
      end;

  if (Edit1.Text <> '') and(Edit1.Text[1] in ['a'..'z']) then
    begin
      i := Edit1.SelStart;
      Edit1.Text := StringReplace(Edit1.Text, Edit1.Text[1], UpperCase(Edit1.Text[1]), []);
      Edit1.SelStart := i;
    end;
end;
