DataGrid being a "cell widget", it will be "re-rendered" regularly, losing all modifications you manually did to the DOM tree.
-- You can "persist" your changes using setRowStyles for classnames applied to a TableRowElement, or custom column with overridden getCellStyleNames for classnames applied to a TableCellElement, or a custom CellTableBuilder for more complex custom rendering; or you can use a RedrawEvent.Handler to reapply your changes every time the grid is re-rendered.

I am trying to apply background colour to some rows dynamically based on some program logic, but I can see that the colour is disspearing on any further row selection.I used two approaches to change the colour.1) baseGrid.getRowElement(i).getCells().getItem(0). addClassName(<css style>);
Use a setRowStyles(), with a RowStyles implementation that returns <css style>
2)TableCellElement cell = grid.getRowElement(i).getCells().getItem(colIndex); cell.getStyle().setProperty(" background", "#DDDDDD"); Could you please suggest any alternative ways I can do it. so that the background colour of the rows do not change on any further row selection?Thanks,Santanu
