FarPoint.Win.Spread.NamedStyle outstyle = new FarPoint.Win.Spread.NamedStyle();
instyle.BackColor = Color.Yellow;
outstyle.BackColor = Color.Aquamarine;
FarPoint.Win.Spread.FilterColumnDefinition fcd = new FarPoint.Win.Spread.FilterColumnDefinition(1, FarPoint.Win.Spread.FilterListBehavior.SortByMostOccurrences |  
FarPoint.Win.Spread.FilterListBehavior.Default);
FarPoint.Win.Spread.FilterColumnDefinition fcd1 = new FarPoint.Win.Spread.FilterColumnDefinition(2, FarPoint.Win.Spread.FilterListBehavior.Default);
FarPoint.Win.Spread.FilterColumnDefinition fcd2 = new FarPoint.Win.Spread.FilterColumnDefinition(3);
fcdc.Insert(0, fcd);
fcdc.Insert(1, fcd1);
fcdc.Insert(2, fcd2);
FarPoint.Win.Spread.StyleRowFilter sf = new FarPoint.Win.Spread.StyleRowFilter(fpSpread1.ActiveSheet, instyle, outstyle);
