Hi Suresh,

Wb Dynpro applications are made up of Web Dynpro Components & Models. Web Dynpro Components are collection of views and controllers.By default Web Dynpro Components has the following controllers Component Interface View Controller,Component Interface Controller,Component Controller all oter are optional.

Interface Controllers:An Interface Controller is the only part of a component that is accessible to other components If any data, methods or events need to be exposed to other Components they must be exposed in Components Interface Controller.

Component Controller & Custom Controller:For each component a Component Controller is defined by default.

Component Controller should act as a processing layer b/w model and views and take no part in how the data is visualised.

Custom Controllers are essentially same as Component Controller but u can create them when needed.you can create Custom Controller whenever u want to encapsulate seperate logic.u can have multiple Custom Controllers.
