title: Refresh dataset when applying a filter
body: <p>I have an TRxQuery in Delphi 5 (which descends from TQuery) bound to a grid. I'm adding a filter edit box and want to filter the grid as the user types. Is there a way to filter the dataset without closing and reopening the query as this causes an unwanted flicker.</p>
  
  <p>Many thanks</p>
