There are no property setting you can use to do this. But you can handl ethe PrepareViewViewStyleInfo event, and dynamically set the CellTipText there to display a cell tip when the mouse hovers over a cell.
private void gridDataBoundGrid1_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)
{
if(e.ColIndex > 0 && e.RowIndex > 0)
e.Style.CellTipText = e.Style.Text;
}
