Developing ASP.NET Server Controls

ASP.NET server controls are components that run on the server and encapsulate user-interface and other related functionality. They are used in ASP.NET pages and in ASP.NET code-behind classes. This section contains background information and examples to help you develop your own ASP.NET server controls.

**Note   **The terms ASP.NET page and Web Forms page are used interchangeably in the documentation.
