Creating Client Components and Controls
.NET Framework 4
The topics in this section provide tutorials for creating client components that are based on the Microsoft Ajax Library. The Microsoft Ajax Library adds a type system and extensions to ECMAScript (JavaScript) objects in order to provide namespaces, inheritance, interfaces, enumerations, reflection, and helper functions for strings and arrays. The library also provides the base client object types Component, Control, and Behavior classes from which you can derive to provide rich client functionality.
