title: Missing Row in Datatable Modified property
body: <p>Updating the first record listed in my <code>DataGridView</code> that is bound to my <code>DataTable</code>.  When I run Save process I run through this line of code to get all records that have been modified:</p>
  
  <pre><code>DataTable modifiedRows = unitDataDT.GetChanges(DataRowState.Modified);
  </code></pre>
  
  <p>If I have changed the first record in my <code>DataGridView</code> my modifiedRows <code>DataTable</code> is Null.
  If I change any of the following records they are in my modifiedRows <code>DataTable</code>.<br>
  I have tried changing other records in my <code>DataGridView</code> first and then changing the first record then running the Save process and still....other records are there and the first record is not.....</p>
  
  <p>Also....I checked the unitDataDT and it has the change.
  I sorted the datagridview to try and update a different record and it still did not add the change to the modifiedRows Datatable....so it seems to not work for the first record listed in the DataGridView.</p>
  
  <p>Any ideas?</p>
