You can include only those Events that are useful for your requirement.

Hi Sravanti,

As per my knowledge,Its not compulsary to use all the events at a time. But if u use Intialization, u must use start-of-selection compulsarily. unless u won't get the output screen as u expected.

Maha.

hi sravanthi,

The answer is "NO". It is not compulsory. It depends upon your requirement.
