I'm servicing an old application that uses Web Forms. This application uses Iframe to make a kind of layout reuse.

The problem is that while doing this, a lot of code is being repeated, and I would like a solution for that.

I come from PHP and Python, where the frameworks use main layouts, which can be extended by the views used. I have no idea how to do this in Web Forms (or even if it is possible to do this).

Is there any way to use a main layout with ASPX files? How to do this?

What you are looking for is called MasterPage, it contains the components and visual elements that are shared by all the pages of your WebForms application, below an example.

Site.master

<%@ Master Language="C#" AutoEventWireup="true" CodeFile="Site.master.cs" Inherits="Site" %>
 <html>

  <head>
    <asp:ContentPlaceHolder id="head" runat="server">
    </asp:ContentPlaceHolder>
  </head>

  <body>
    <form id="form1" runat="server">
      <div>
        <!-- Aqui vão as suas páginas de conteúdo-->
        <asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">

        </asp:ContentPlaceHolder>
      </div>
    </form>
  </body>
 </html>

Now when creating your content pages that should be presented by this template you must declare it as such.

<%@ Page Language="C#" MasterPageFile="~/Site.master" ... %>
