Create Composite Control using Ajax Toolkit Controls

Introduction

Ajax Control Toolkit allows the developer to create Web applications that can update data on the Web page without a complete reload of the page, and contain many controls with very interesting features: popup panels, resizable controls, floating controls and others.

Often you want a control with some features of some other controls, so you can achieve the goal of joining more controls in a single control as CompositeControl.
Composite Controls are controls that combine multiple controls together to form a new reusable control. For example, I want to create a control container that makes resizable, collapsible, draggable all guest controls as IFrame or others.
ResizableControlExtender, CollapsiblePanelextender, DragPanelExtender controls extend their own features to the Panel written on TargetControlID property so you can create a mix like this:

MVC Architecture Model In ASP.NET

Image
When developing ASP.NET applications the need of reducing code duplication increases along with their complexity. This is because testing and performing changes become very difficult tasks when having many different sources of code with the same functionality. Model View Controller architecture (or pattern) allows us to separate different parts of our applications into tiers to fulfill this need. MVC Overview Model View Controller architecture aims to separate an application into three parts: Model:  It is the business logic of an application. From an object oriented perspective it would consist of a set of classes that implement the critical functionality of an application from a business point of view. View:  It can consist of every type of interface given to the user. In ASP.NET the view is the set of web pages presented by a web application.
