Tabsheet componentCount returning always Zero ?

Dear Experts,

when I Execute the following:

procedure TForm1.ClearForm(AForm : TsuiTabSheet);
var i : Integer;

begin

        begin
         For i := 0 to AForm.ComponentCount -1 do
             begin
               if (AForm.Components[i] is TcxTextEdit) then
                  begin
                     (AForm.Components[i] as tcxTextEdit).Text := '';
                  end;
             end;
       end;


end;

The TsuiTabSheet is a Tabsheet from a Page Control Component... since it was not working... I've checked the value returned
by AForm.ComponentCount and it is zero.

I would like to check all components on the The Tabsheet page and if they are TextEdit, clear their content...

any idea?

Thank you!

Dave

You should try something like that

  for i := 0 to ComponentCount-1 do
    begin
    if Components[i] is TControl then
      begin
      if ((Components[i] as TControl).Parent.Name = 'TabSheet1')
        and (Components[i] is TEdit) then
        (Components[i] as TEdit).Text := '';
      end;
    end;

use Controls, not Components
ie.

procedure TForm1.ClearForm(AForm : TsuiTabSheet);
var i : Integer;
begin
        begin
         For i := 0 to AForm.ControlCount -1 do
             begin
               if (AForm.Controls[i] is TcxTextEdit) then
                  begin
                     (AForm.Controls[i] as tcxTextEdit).Text := '';
                  end
             end;
       end;
end;
