Using Enhanced Filtering

When the control has enhanced filtering turned on, the user can drop-down a list of available filters to apply to the data.

The default filter that is displayed depends on the data in the column. The filter can be a number, text, date, or color filter.

The filters are described in the following table.

Filter Type Description

Equals Values in rows are equal to condition
Does Not Equal Values in rows do not equal condition
Greater Than Values in rows are greater than condition
Greater Than Or Equal To Values in rows are greater than or equal to condition
Less Than Values in rows are less than condition
Less Than Or Equal To Values in rows are less than or equal to condition
Between Values in rows are greater than one condition and less than another condition
Top 10 Values in the rows with the ten highest values
Above Average Values in the rows that are above the average of the values in all the rows
Below Average Values in the rows that are below the average of the values in all the rows

Custom Filter Values in rows that meet the conditions of a custom filter

Users can specify wildcards in conditions. The "?" character represents any single character. The "*" character represents any series of characters.

When the user chooses a filter, the control either filters the data to display only the items that match the filter criteria, or the control displays the rows that meet the criteria with one appearance, and the rows that do not meet the criteria with another appearance. For information about setting the styles for rows, see Creating Filtered Rows and Setting the Appearance.

Using Code

Set the AutoFilterMode property to Enhanced, create a filter style, and then apply the filter to the sheet.

Example

The following example creates an enhanced filter in the first three columns. Add different types of data to see the various filter options.

C#
Copy Code
FpSpread1.Sheets[0].AutoFilterMode = FarPoint.Web.Spread.AutoFilterMode.Enhanced;
FarPoint.Web.Spread.NamedStyle instyle = new FarPoint.Web.Spread.NamedStyle();
FarPoint.Web.Spread.NamedStyle outstyle = new FarPoint.Web.Spread.NamedStyle();
instyle.BackColor = Color.Yellow;
outstyle.BackColor = Color.Aquamarine;
FarPoint.Web.Spread.FilterColumnDefinition fcd = new FarPoint.Web.Spread.FilterColumnDefinition(1, FarPoint.Web.Spread.FilterListBehavior.SortByMostOccurrences | FarPoint.Web.Spread.FilterListBehavior.Default);
FarPoint.Web.Spread.FilterColumnDefinition fcd1 = new FarPoint.Web.Spread.FilterColumnDefinition(2);
FarPoint.Web.Spread.FilterColumnDefinition fcd2 = new FarPoint.Web.Spread.FilterColumnDefinition();
FarPoint.Web.Spread.StyleRowFilter sf = new FarPoint.Web.Spread.StyleRowFilter(FpSpread1.Sheets[0], instyle, outstyle);
sf.AddColumn(fcd);
sf.AddColumn(fcd1);
sf.AddColumn(fcd2);
FpSpread1.Sheets[0].RowFilter = sf;
VB
Copy Code
FpSpread1.Sheets(0).AutoFilterMode = FarPoint.Web.Spread.AutoFilterMode.Enhanced
Dim instyle As New FarPoint.Web.Spread.NamedStyle()
Dim outstyle As New FarPoint.Web.Spread.NamedStyle()
instyle.BackColor = Drawing.Color.Yellow
outstyle.BackColor = Drawing.Color.Aquamarine
Dim fcd As New FarPoint.Web.Spread.FilterColumnDefinition(1, FarPoint.Web.Spread.FilterListBehavior.SortByMostOccurrences Or FarPoint.Web.Spread.FilterListBehavior.Default)
Dim fcd1 As New FarPoint.Web.Spread.FilterColumnDefinition(2)
Dim fcd2 As New FarPoint.Web.Spread.FilterColumnDefinition()
Dim sf As New FarPoint.Web.Spread.StyleRowFilter(FpSpread1.Sheets(0), instyle, outstyle)
sf.AddColumn(fcd)
sf.AddColumn(fcd1)
sf.AddColumn(fcd2)
FpSpread1.Sheets(0).RowFilter = sf
