title: Lazy Load Data in a GWT DataGrid
body: <p>Is it possible to load data lazily into a GWT DataGrid, similarly to how the GWT CellList lazily loads data?</p>
  
  <p>I have a GWT DataGrid that can potentially bring back hundreds of rows, but only about 20 rows are displayed at a time. When this occurs, the loading of the grid is quite slow. </p>
  
  <p>I want to use a DataGrid instead of a CellTList because I have multiple columns of data that need to be displayed. And I've opted for a DataGrid instead of a CellTable because I want the header columns to be fixed.</p>
