Declaration

C#

public class PivotGridGroupCollection :

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, two fields (“Country” and “Customer”) are combined into a new group at design time, and another two fields (“Category” and “Product”) are combined into a new group at runtime, in this order. This ensures that the “Country” field is followed by “Customer”, and the the “Category” field is followed by “Product”. If you drag the “Region” field and drop it to another area, the “Customer” field accompanies it. This behavior is also true for the second group.
