Now i found that the custom action(menu Item) in ECB is displayed for both document item and document folder. So how to apply custom action only for document item?

Answer 1

Are you using list as your RegistrationType?

Try using ContentType as your RegistrationTypeand specify the guid of the Document Content Type (I think its 0x0101) in your RegistrationID.
