title: How to Filter rows in a DataView
body: <p>I have a <code>DataGrid</code> that uses a <code>DataView</code> as the source. My DataView has 81 records in it. I want to filter only that rows that have an <code>Item_Number</code> that is greater than or equal to the Item the user enters. This is what I have, but its not filtering my rows.</p>
  
  <pre><code>PrintView.RowFilter = "Item_Number &gt;= 'val'";
  PrintView.RowStateFilter = DataViewRowState.ModifiedCurrent;
  
  dgPrintTicket.DataSource = PrintView;
  BindDataGrid();
  </code></pre>
  
  <p><code>PrintView</code> is my DataView. When I debug and check rows after I filter the rows, it shows nothing has changed. The <code>PrintView</code> stays the same.</p>
