title: Best practice for updates to a single datatable row
body: <p>Why does the first method below work?  I would have thought that the variable 'row' is completely separate from anything else, such as a row in DataTable1.  Also, is there a drawback to using the first method?  For changes to lots of columns in a single row, I'd rather do it that way.</p>
  
  <pre><code>dim row = Me.DataSet1.DataTable1(0)
  row.Item1=123
  DataTable1TableAdapter.Update(Me.DataSet1.DataTable1)
  </code></pre>
  
  <p>OR</p>
  
  <pre><code>DataSet1.DataTable1(0).Item1=123
  DataTable1TableAdapter.Update(Me.DataSet1.DataTable1)
  </code></pre>
