Event Data

The CustomGroupInterval event's data class is PivotCustomGroupIntervalEventArgs. The following properties provide information specific to this event:

Property Description
Field Gets the field being processed. Inherited from PivotFieldEventArgsBase<T>.
GroupValue Gets or sets a group value. Inherited from PivotCustomGroupIntervalEventArgsBase<T>.
Value Gets the processed field value. Inherited from PivotCustomGroupIntervalEventArgsBase<T>.


Values of column and row fields can be grouped into bigger ranges. You can select one of the predefined group modes available with the PivotGridFieldBase.GroupInterval property. If none of these group modes matches your requirements, you can implement custom grouping.

To custom group a field’s values, set the PivotGridFieldBase.GroupInterval property to Custom and handle the CustomGroupInterval event to implement custom grouping logic. The event fires for each value of a field. While handling the event, use the GroupValue parameter to specify the group that will own the currently processed value. For values to be displayed in a single group, provide the same value for the GroupValue parameter.

Objects assigned to the GroupValue property must be of the same type for all values of a particular field.


The CustomGroupInterval is not supported in server and OLAP modes.
