Represents a collection of field groups.

Namespace: DevExpress.Xpf.PivotGrid

Assembly: DevExpress.Xpf.PivotGrid.v18.2.dll

Declaration

C#

public class PivotGridGroupCollection :
    PivotChildCollection<PivotGridGroup>,
    ILockable

VB.NET

Public Class PivotGridGroupCollection
    Inherits PivotChildCollection(Of PivotGridGroup)
    Implements ILockable

Related API Members

The following members return PivotGridGroupCollection objects:

• PivotGridControl.Groups

Remarks

The DXPivotGrid provides the capability to arrange fields into groups. Fields which are grouped cannot be separated by end-users by dragging one of them to a different area. Field groups are represented by PivotGridGroup objects, and these are stored within the PivotGridControl.Groups collection.

To learn more, see Field Groups.

Example

The following example demonstrates how to combine fields into a group.

In this example, three fields (“Country”, “Region” and “City”) are combined in a new group, in this order. This ensures that the “Country” field is followed by “Region”, which is in turn followed by “City”. If the “Region” field is dragged to another area, the other fields accompany it.
