title: updating dataset when adding a new field in database in c#
body: <p>I have made a database and created a table with five fields and used add new datasource  and added a new dataset by using that. And I have made a form and inserted all fields by dragging them into the form and changed lots of the properties.  Now I need to add a new field into the table in database. Do I have to create a new datasource and a new dataset and do everything from beginning or there is a way to update the datasource and dataset so that the new field automatically appears in them?
  Any answer would be appreciated. </p>
