title: Replacing the data in dojox.grid.enhancedGrid
body: <p>I have created a dojox.grid.EnhancedGrid. The grid is working fine.
  In some of the rows when the data for any column is blank/null is there, It is shown in grid with 3 dots(...).  Is there any way to replace those blank dots with blank(no dots).
  Or Is it possible to replace a specific value returned from the server with another value.</p>
  
  <p>Thanks in Advance</p>
