User controls behave like mini ASP.NET pages that can be used across many pages and have an .ascx extension.

Custom control in asp.net
- 1. WELCOME TO
- 3. • ASP.NET allows the users to create controls. These user defined controls are categorized into: • User controls • Custom controls • User Controls • User controls behaves like miniature ASP.NET pages or web forms, which could be used by many other pages. These are derived from the System.Web.UI.UserControl class. These controls have the following characteristics: • They have an .ascx extension. • They may not contain any <html>, <body>, or <form> tags. • They have a Control directive instead of a Page directive.
- 4. • Custom Controls • Custom controls are deployed as individual assemblies. They are compiled into a Dynamic Link Library (DLL) and used as any other ASP.NET server control. They could be created in either of the following way: • By deriving a custom control from an existing control • By composing a new custom control combing two or more existing controls. • By deriving from the base control class. • To understand the concept, let us create a custom control, which will simply render a text message on the browser.
