How to enable Workflow in .Net API

Hi,

I found the link (https://community.sagecrm.com/partner_community/b/hints_tips_and_tricks/archive/2008/03/15/workflow-buttons-in-pages-built-using-the-net-api.aspx) where you can create your own custom workflow buttons but i would like to to avoid this (if possible).

I am only looking for something that will enable the workflow that's all. Is it possible, if so how?
