Example

This example filters out items when typing in the combo cell.

FarPoint.Web.Spread.AutoFilter afilter = new FarPoint.Web.Spread.AutoFilter();
afilter.Enabled = true;
afilter.MatchingSource = FarPoint.Web.Spread.FilterMatchingSource.AllColumns;
afilter.MinPrefixLength = 1;
afilter.MaxFilteredItem = 10;

System.Data.DataSet ds = new System.Data.DataSet();
System.Data.DataTable emp = new System.Data.DataTable("Employees");
System.Data.DataTable div = new System.Data.DataTable("Division");
emp.Columns.Add("LastName");
emp.Columns.Add("FirstName");
emp.Rows.Add(new Object[] { "Jones", "Marianne" });
emp.Rows.Add(new Object[] { "Fieldes", "Anna" });
emp.Rows.Add(new Object[] { "Johnson", "Anna" });
div.Columns.Add("Section");
div.Columns.Add("Specialty");
div.Rows.Add(new Object[] { "Finance", "Taxes" });
div.Rows.Add(new Object[] { "Mergers", "Legal" });
ds.Tables.AddRange(new System.Data.DataTable[] { emp, div });
FarPoint.Web.Spread.MultiColumnComboBoxCellType mccbct = new FarPoint.Web.Spread.MultiColumnComboBoxCellType();
mccbct.DataSource = ds;
mccbct.VerticalAlign = VerticalAlign.Top;
mccbct.AutoFilter = afilter;
FpSpread1.ActiveSheetView.Cells[0, 0].CellType = mccbct;
