More info
I tried to get the page number in a new program, and I get succelly.

So I review the code of my program

I my program I create the tabsheets dinamic with this code:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i  TabSheet
:= TTabSheet.Create (frEditor.Contenedor);   TabSheet.Name:=
stNombre+IntToStr (nTabSheet);   TabSheet.PageControl :=
frEditor.Contenedor;   TabSheet.Caption := stNombre+Ext; 
 TabSheet.Tag:= nTabSheet; 
I add this line:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i  
 TabSheet.Parent := frEditor.Contenedor;             
Any help?

What is
Code: [Select]Contenedor
1) Is it TPageControl ?
and
2) Is it created ?

Yes, to all questions.
Thanks Blaazen for the aswer, but a few minutes ago I found de
solution.
I have a mainform, which creates (in his oncreate event)  a second
form, and a TPageControl, and in the TPageControl creates a TabSheet
in this second form.
So I found that I want to access to any property of the TPageControl,
I have to do some thing like this:

Code: Text  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i  
MainForm.SecondForm.PageControl1.AnyProperty;
