Class PivotEngine

This class encapsulates pivoting calculation support. To use it, first populate the PivotColumns and PivotRows collections to define the properties being pivoted. Then you populate the PivotCalculations collection to define the values you would like to see populated.

Properties

AllowedFields

Gets a collection of FieldInfo objects that hold the field names that you want to make visible in the engine. The names can be either public property names of the underlying data objects or they can be expression field.

Declaration

public List<FieldInfo> AllowedFields { get; }

Property Value

Type	Description
System.Collections.Generic.List<FieldInfo>

Remarks

If your data contains fields that you do not want exposed to the pivoting process, then add the names of the properties you want to include to this list. All other fields will be excluded.

If you leave this collection empty, the default behavior will be to make all public properties available for use in the pivot table.

To add an expression field, set the FieldInfo.FieldType to FieldsType.Expression and set FieldInfo.Expression to be a string holding a well formed expression defining the value that should appear in this field.

ApplyFormattedSummary

Gets or sets the formatted total value for the sub-total/grand total cells.

Declaration

public bool ApplyFormattedSummary { get; set; }

Property Value

Type	Description
System.Boolean

CacheRawValues

Gets or sets whether underlying raw values are cached as the Pivot is being built. If these values are cached, then GetRawItemsFor method calls do not require traversing the underlying data to complete.

Declaration

public bool CacheRawValues { get; set; }

Property Value

Type	Description
System.Boolean

ColumnCount

Gets the number of columns in the PivotTable.

Declaration

public int ColumnCount { get; }

Property Value

Type	Description
System.Int32

CoveredRanges

Gets a list of CoveredCellRange objects that specify the cells that need to be covered.

Declaration

public List<CoveredCellRange> CoveredRanges { get; }

Property Value

Type	Description
System.Collections.Generic.List<CoveredCellRange>

DataSource

Gets or sets data source for this PivotTable. This object should be either an IEnumerable List or a DataTable.

Declaration

public object DataSource { get; set; }

Property Value

Type	Description
System.Object

DataSourceList

Used internally. Gets or sets an IEnumerable List that is used as the data source for the PivotTable. The default behavior is to initialize this list from DataSource.

Declaration

public virtual IEnumerable DataSourceList { get; set; }

Property Value

Type	Description
System.Collections.IEnumerable

EditCellsInfo

Gets or sets the edited cells information.

Declaration

public Dictionary<string, Array> EditCellsInfo { get; set; }

Property Value

Type	Description
System.Collections.Generic.Dictionary<System.String, System.Array>

EmptyPivot

If you apply a filter which filters out all items in the underlying data source, then this "EmptyPivot" property will be set true. The RowCount and ColumnCount will be set to one, and the Engine[0, 0] will hold the value.

Declaration

public bool EmptyPivot { get; }

Property Value

Type	Description
System.Boolean

EmptyPivotString

Gets or sets the string that appears when no items are present in a Pivot result.

Declaration

public string EmptyPivotString { get; set; }

Property Value

Type	Description
System.String

EnableDataOptimization

Gets or sets a value to indicate whether the data should be loaded in an optimized way to render huge data with less time consumption.

Declaration

public bool EnableDataOptimization { get; set; }

Property Value

Type	Description
System.Boolean

Remarks

Setting this property indicates that the PivotEngine should populate the data based on combining the population logics used in both PivotEngine and IndexEngine. There is no need to set the properties "UseIndexedEngine" and "EnableOnDemandCalculations" is true when using the property "EnableDataOptimization". This feature will work significantly with less time consumption to populate and the render the values even using large pivots.

EnableLazyLoadOnDemandCalculations

When setting the EnableOnDemandCalculations property to true, it allows the UI to trigger the summary calculations during the application idle cycles.

Declaration

public bool EnableLazyLoadOnDemandCalculations { get; set; }

Property Value

Type	Description
System.Boolean

Remarks

This means that the summaries in the Pivot control may be fully populated when the user does something like sort/filter a PivotItem which avoids a delay. If EnableOnDemandCalculations is false, setting this property has no effect.

EnableOnDemandCalculations

Gets or sets whether the calculations are postponed until the value is requested through the Indexer on PivotEngine. The default value is false.

Declaration

public bool EnableOnDemandCalculations { get; set; }

Property Value

Type	Description
System.Boolean

Remarks

The default calculation behavior is for all the value cells to be populated during the call to PivotEngine.Calculate. When EnableOnDemandCalculations is set true, then the calculations are postponed until there is an initial request for a calculated value. At that time, the calculation is completed and stored. Subsequent requests for a value return the stored value instead of redoing the calculations.

Setting the EnableOnDemandCalculations allows the initial display of a large pivot table as only the visible cells will need to be calculated. This speed up in initial display, does come at the cost of a slight degradation in first-time scrolling performance as the cells that are newly made visible through the scrolling require a calculation to be completed. This setting is not available when RowPivotsOnly is false.

EnableSubTotalHiding

Gets or sets whether PivotGrid control should hide the sub-totals in engine level when setting the property ShowSubTotals to false.

Declaration

public bool EnableSubTotalHiding { get; set; }

GetValue

Gets or sets a GetValueDelegate delegate that returns a property value for a given object.

Declaration

public GetValueDelegate GetValue { get; set; }

Property Value

Type	Description
GetValueDelegate

Remarks

If this member is null, the IndexEngine will use reflection to obtain property values from objects in the DataSource. NOTE: Usually a well written delegate can provide values more efficiently than using reflection. For performance improvements, you will want to provide a well written delegate for this property.

ResumeComputations(Boolean)

Resumes calculations after a call to suspend computations with the option of re-setting the PivotTable.

Declaration

public void ResumeComputations(bool resetPivotCollections)

Parameters

Type	Name	Description
System.Boolean	resetPivotCollections	Returns true if the PivotTable should be recomputed; otherwise, false.

Resumes calculations after a call to "SuspendComputations" method with an option of re-setting the PivotTable.

Declaration

public void ResumeComputations(bool resetPivotCollections, bool shouldRefresh)

Parameters

Type	Name	Description

Sort different values by calculation based on column index and multi-column sorting.

Declaration

public void SortByCalculation(int colIndex, bool isMultiColumn)

Parameters

Type	Name	Description
System.Int32	colIndex	The column index.
System.Boolean	isMultiColumn	Returns true if multi-column sorting operation is done; otherwise, false.

Performs sorting operation in column header.

Declaration

public void SortColumnHeader(int colHeaderIndex)

Parameters

Type	Name	Description
System.Int32	colHeaderIndex	The index of column header.

SuspendComputations()

Suspends calculations as PivotItems are added or removed from either RowPivots or ColumnPivots collections or when PivotCalculations are added or removed from the PivotCalculations collection.

Declaration

public void SuspendComputations()

Remarks

By default, calculations are always suspended. Once you have populated all the appropriate collections to define your PivotTable, you can call Populate() method to tell the engine to generate the PivotTable contents that you can access by indexing the engine.
