How to dynamically insert inputs into a form?

Question

ASP.NET

Good afternoon, I am writing a simple application on asp.net webforms, c# programming language.
Here is my page code:

<%@ MasterType VirtualPath="~/Site1.Master" %>
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Registration.aspx.cs" Inherits="LkMiac.Registration" MasterPageFile="~/Site1.Master" Title="Войти в личный кабинет"%>

<asp:Content ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<!-- Вот сюда мне нужно вставить код -->
</asp:Content>

I have to have a dynamic form, the field names come from another resource in json format. How can I implement this?
For the test, I created a simple element:

Label label = new Label();
label.Text = "Я это создал динамически";

And how can I add it to the part of the page I need?

Answer 1

Create a user control in it after initialization add this.Controls.Add(label);

Answer 2

Webforms has been dead for a long time, just wondering why?
