Hi guys,
while creating a webdynpro component, we wil get two options like webdnpro component and webdynpro component interface.
Here what is the webdynpro component interface and when will use it?
Thanks in advance
Srinivas
Srinivas,
Component interface , as the name suggest all the interface for webdynpro components.
You can see examples like ALV, OVS,VALUE_HELP are some of the interface components which provides a pattern of behavior to the implementing components. You have to see this as interface in OO.

Hi Srinivas,
Component Interface is nothing but ABAP OOPS Interface. Once you create the Component Interface, automatically system will create Interface Controller. Here we can create only Method defintion,Node and Event creation. Which can be implement in Some other Webdynpro components.Here we can not desing UI elements and also we can not create implementation.
Thanks and Regards
Vijay

Hi,
Component interface definitions allow you to generically define a uniform interface structure and later use it in a variety of application components. The advantage of this procedure lies in the fact that in a distributed development the interfaces of all components that use the interface definition reliably contain a particular set of controller elements (methods, context elements, etc.) and interface views, which can be addressed by the developers of using components. The developer of a using component does not need to know which actual implementation of the interface is used u2013 this can be determined dynamically at runtime.
