VB.NET

Public Property GroupValue As Object

Property Value

Type	Description
Object	An object that represents the group value.

Remarks

The ASPxPivotGrid.CustomGroupInterval event enables you to group axis values using your own criteria. Use the GroupValue property to specify group values.

Example

The following example implements custom group intervals in the Pivot Grid to group the Product Name field values into three ranges: A-E, F-S, and T-Z (according to the initial characters of the product names). The following expression is used:

Iif(Substring([Product Name], 0, 1) < 'F', 'A-E', Substring([Product Name], 0, 1) < 'T', 'F-S', 'T-Z')

The image below shows the result:
