本文将通过一个具体是示例为大家演示如何将多个字段合并成组。

本例中合并的字段为Country、Region和City这三个字段，我们将它们合并为一个组，进而实现：当我们拖拽字段Country到另一个区域时，Region和City也会自动跟着进入新的区域；当我们拖拽字段Region到另一个区域时，City也会自动跟着进入新的区域。下图演示的就是拖拽字段Region到Filter Header Area的效果图：

代码如下：

C#

using DevExpress.XtraPivotGrid;

PivotGridField fieldCountry = pivotGridControl1.Fields["Country"];
PivotGridField fieldRegion = pivotGridControl1.Fields["Region"];
PivotGridField fieldCity = pivotGridControl1.Fields["City"];
// Add a new group which combines the fields.
pivotGridControl1.Groups.Add(new PivotGridField[] {fieldCountry, fieldRegion, fieldCity});

VB

Imports DevExpress.XtraPivotGrid

Dim fieldCountry As PivotGridField = PivotGridControl1.Fields("Country")
Dim fieldRegion As PivotGridField = PivotGridControl1.Fields("Region")
Dim fieldCity As PivotGridField = PivotGridControl1.Fields["City")
' Add a new group which combines the fields.
PivotGridControl1.Groups.Add(new PivotGridField() {fieldCountry, fieldRegion, fieldCity})
