Example

This example creates a filter collection for filtering. (Bound to Northwind.mdb, Employee table)

FarPoint.Win.Spread.FilterColumnDefinitionCollection fcdc;
this.fcdc = new FarPoint.Win.Spread.FilterColumnDefinitionCollection();
 
FarPoint.Win.Spread.NamedStyle instyle = new FarPoint.Win.Spread.NamedStyle();
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);
foreach(FarPoint.Win.Spread.FilterColumnDefinition x in fcdc)
{
      sf.AddColumn(x);
}
fpSpread1.ActiveSheet.RowFilter = sf;

fcdc.Changed += new System.ComponentModel.CollectionChangeEventHandler(fcdcChanged);

private void fcdcChanged(object sender, System.ComponentModel.CollectionChangeEventArgs e)
{
      MessageBox.Show("The collection has changed.");
}
