Remarks
To group values of column or row fields, set the group interval of the data binding. The Pivot Grid allows you to group date/time, numeric, and string field values.
The following code shows how to set the DateYear group interval for a field:
<DataBindingSerializable>
<dx:DataSourceColumnBinding ColumnName="OrderDate" GroupInterval="DateMonth" />
</DataBindingSerializable>
</dx:PivotGridField>
</Fields>
See the following help topic for details: Grouping.
