FieldValueSplitData Class

Represents a cell created when splitting a field value cell.

Namespace: DevExpress.XtraPivotGrid.Data

Assembly: DevExpress.PivotGrid.v19.2.Core.dll

Declaration

public class FieldValueSplitData
Public Class FieldValueSplitData

Remarks

The FieldValueSplitData class instances are used when handling the CustomFieldValueCells event. A collection of FieldValueSplitData objects is passed to the event parameter's Split method. Each element of the collection represents a single cell that should be created after splitting the current one. The entire collection defines how the current cell is split.

The FieldValueSplitData class provides the FieldValueSplitData.NestedCellCount property that defines the size of the newly created cell, and the FieldValueSplitData.Value property that specifies the cell's value.

Examples

The following example demonstrates how to split field value cells.In this example, the Grand Total column header is split into two cells: Price and Count. To do this, the CustomFieldValueCells event is handled, and the event parameter's Split method is used. Cells that should be split are identified by a predicate that returns true for those cells. The quantity, size and captions of newly created cells are specified by an array of cell definitions (the FieldValueSplitData objects).
