Class PivotComputationInfo

This class holds the information needed for the calculations that appear in a Pivot control. For each calculation seen, there is an associated PivotComputationInfo object that is added to the PivotComputationInfo collection.

BaseItem

Gets or sets the value of base item for calculations.

Declaration

public string BaseItem { get; set; }

Property Value

Type
System.String

CalculationName

Gets or sets what needs displayed in the PivotTable if more than one calculation is included in the Pivot control.

Declaration

public string CalculationName { get; set; }

Property Value

Type
System.String

CalculationType

Gets or sets the calculation type for this computation object.

Declaration

public CalculationType CalculationType { get; set; }

Property Value

Type
CalculationType

DefaultValue

Gets or sets the default value to be used when this summary calculation gets null value.

Declaration

public object DefaultValue { get; set; }

Property Value

Type
System.Object

Description

Gets or sets a description for this calculation.

Declaration

public string Description { get; set; }

Property Value

Type
System.String

DisplayOption

This is used to display or hide the computation values in PivotEngine based on the option provided.

Declaration

public DisplayOption DisplayOption { get; set; }

Property Value

Type
DisplayOption

EnableHyperlinks

Gets or sets whether this calculation column should be hyperlinked when RowPivotsOnly is true in the PivotEngine.

Declaration

public bool EnableHyperlinks { get; set; }

Property Value

Type
System.Boolean

Expression

Used internally for formula calculation types.

Declaration

public FilterExpression Expression { get; set; }

Property Value

Type
FilterExpression

FieldCaption

Gets or sets the title you want to see in the header for this item.

Declaration

public string FieldCaption { get; set; }

Property Value

Type
System.String

FieldHeader

Gets or sets the title you want to see in the header for this item.

Declaration

public string FieldHeader { get; set; }

Property Value

Type
System.String

FieldName

Gets or sets the name of the property to be used in this calculation.

Declaration

public string FieldName { get; set; }

Property Value

Type
System.String

FieldType

Gets or sets the value of field type.

Declaration

public string FieldType { get; set; }

Property Value

Type
System.String

Format

Gets or sets the format string used to format this calculation results in the Pivot control. Default format string is #.##.

Declaration

public string Format { get; set; }

Property Value

Type
System.String

Formula

Gets or sets a formula that defines the value as an algebraic expression of other computations where these computations are referenced by their CalculationName enclosed within square brackets.

Declaration

public string Formula { get; set; }

Property Value

Type
System.String

Remarks

For example, if the value of formula is "[AvgPrice]-[AvgCost]", then there should be two other computations whose names are AvgPrice and AvgCost, and the value displayed for this computation should be the difference between those two values.

InnerMostComputationsOnly

Gets or sets whether the aggregation result should appear only for the innermost level.

Declaration

public SummaryDisplayLevel InnerMostComputationsOnly { get; set; }

Property Value

Type
SummaryDisplayLevel

IsTopColumnSummary

Gets or sets whether this calculation column only displays the subtotals for top column

Declaration

public bool IsTopColumnSummary { get; set; }

Property Value

Type
System.Boolean

PadString

This is used to specify a custom string in the PivotComputation column instead of the original cell value. To use this, we must set SummaryType as DisplayIfDiscreteValuesEqual.

Declaration

public string PadString { get; set; }

Property Value

Type
System.String

Summary

Gets or sets the SummaryBase object that is used to define this calculation. This value is automatically set when you specify any non-custom value of SummaryType. If you specify SummaryType.Custom, then you are required to set Summary to be an instance of your custom SummaryBase derived object.

Declaration

public SummaryBase Summary { get; set; }

Property Value

Type
SummaryBase

SummaryType

Gets or sets the SummaryType enumeration for this calculation. Setting it to any value other than "Custom" will properly set the summary.

Declaration

public SummaryType SummaryType { get; set; }

Property Value

Type
SummaryType

Methods

GetComputationTypes()

Returns a sorted list of computation names based on the SummaryType enumerations.

Declaration

public static List<string> GetComputationTypes()

Returns

Type	Description
System.Collections.Generic.List<System.String>	A list of computation names.

GetSchema()

This method is reserved and should not be used. When implementing the IXmlSerializable interface, you should return null (Nothing in Visual Basic) from this method, and instead, if specifying a custom schema is required, apply the System.Xml.Serialization.XmlSchemaProviderAttribute to the class.

Declaration

public XmlSchema GetSchema()

Returns

Type	Description
System.Xml.Schema.XmlSchema	An System.Xml.Schema.XmlSchema that describes the XML representation of the object that is produced by the System.Xml.Serialization.IXmlSerializable.WriteXml(System.Xml.XmlWriter) method and consumed by the System.Xml.Serialization.IXmlSerializable.ReadXml(System.Xml.XmlReader) method.

GetSummaryInstance(SummaryType)

Returns a SummaryBase object of the specified SummaryType.

Declaration

public static SummaryBase GetSummaryInstance(SummaryType st)

Parameters

Type	Name	Description
SummaryType	st	The SummaryType.

Returns

Type	Description
SummaryBase	A SummaryBase object.

ReadXml(XmlReader)

Generates an object from its XML representation.

Declaration

public void ReadXml(XmlReader reader)

Parameters

Type	Name	Description
System.Xml.XmlReader	reader	The System.Xml.XmlReader stream from which the object is deserialized.

ToString()

Converts to string

Declaration

public override string ToString()

Returns

Type	Description
System.String	Calculation name displayed in the PivotTable.

WriteXml(XmlWriter)

Converts an object into its XML representation.

Declaration

public void WriteXml(XmlWriter writer)

Parameters

Type	Name	Description
System.Xml.XmlWriter	writer	The System.Xml.XmlWriter stream to which the object is serialized.

Events

PropertyChanged

Event denoting whether the property is changed.

Declaration

public event PropertyChangedEventHandler PropertyChanged
