FieldValueSplitData(Object, Int32) Constructor

Initializes a new instance of the FieldValueSplitData class.

Namespace: DevExpress.XtraPivotGrid.Data

Assembly: DevExpress.PivotGrid.v23.2.Core.dll

NuGet Packages: DevExpress.PivotGrid.Core, DevExpress.Win.Navigation

Declaration

C#

public FieldValueSplitData(
    object value,
    int nestedCellCount
)

VB.NET

Public Sub New(
    value As Object,
    nestedCellCount As Integer
)

Parameters

Name	Type	Description
value	Object	The value that will be contained in the new cell. Assigned to the FieldValueSplitData.Value property.
nestedCellCount	Int32	An integer value that specifies the number of cells nested in the new cell. This value is assigned to the FieldValueSplitData.NestedCellCount property.

Example

The following example shows how to split the field value cells. In this example, the Grand Total column header is split into two cells: Price and Count. For this, the Split method of the CustomFieldValueCells event is used.
