Update Cell Style on Virtual Grid

I am using virtual grid. After I update a cell text, I can''t change the cell text color. Does anyone know how to do that? Thanks a lot

In a virtual grid, if you want to change a cell''s backcolor, you have to do it by setting e.Style.BackColor in your QeryCellInfo handler. Virtual grids store no information on cells in the grid''s internal storage. So, you do not ''set'' a cell''s backcolor, instead you ''provide'' a cell''s backcolor in QueryCellInfo.
