What is the difference between OnInitialUpdate and OnUpdate?

Answer Posted / priyanka

OnInitialUpdate() is called after a view is first attached
to the doc and before it gets displayed.We can override it
to put some initializations containing info abt the doc.It
calls OnUpdate().
OnUpdate() is called by the framework when the doc has been
modified.It is actually called by UpdateAllViews() to
reflect changes in all the views associated with the doc.
