Hi Meghana

<b>WebDynpro Phase Model</b> describes the life cycle of all Webdynpro Objects.

Yoy will find it in NWDS help itself apart from help.sap.com

Hope this helps

hi meghna,

1. wdDoInit().

this will be called only once when the view is displayed for the first time. In subsequent displays of the view this method will not be called.

3. wdDOModifyView()

this method will be called all the times before rendering the view. This method used for

creating / modifying the UI Elements dynamically.

4. OnAction<>()

This is an event handler, which will be called on the events like Clicking of the button, Selection in dropdown element etc.

5. onPlug<>()

this method will be called on firing either in bound or out bound plug,
