I thought my problem is connecting aspx and c# but it's It was wrong

my tested solution

thanks in advance

i think **Inherits="_3layer_cms.register"** may be issue and page class name instead on **_3layer_cms.register**. — Sanjay Radadiya, Jul 14 '16 at 08:51

Somehow you have copy/paste some code and you have mix page that must have some master page reference but did not have it.

There are two points.

You have the asp:Content that to work you need to reference some master page

 <asp:Content ID="Content2" ContentPlaceHolderID="ContentSection" runat="server">

but the code on that case must not be like that, you are not allow to have html code out side the asp:Content... so probably if you remove all asp:Content will work.

Other bugs

From the other hand the page include <form> not in the way asp.net need to be.

You have mix a page and now if full of bugs...

Start with a new page, make it from visual studio and start build it - not copy/paste some other code that way... there will not work that way... and maybe you need to learn asp.net to understand what the form must be, how its work and all that, later to go to some complicate page like this one.

The form tag must be something like

<form id="form1" runat="server" >

to make your page see the inside controls.

asp:Content just test but I forgot delete. – mohammad Jul 14 '16 at 09:15
I designed first html then I decided to do this with Bootstrap. – mohammad Jul 14 '16 at 09:20
@mohammad the tag `form` is not correct formatted - you design something and then you destroy some elements that you do not know what they are - Correct now the `form` element – Aristos Jul 14 '16 at 09:27
i delete all and i have just one textbox but not work again. – mohammad Jul 14 '16 at 10:02
@mohammad you do not have the `
` - place it
