How to: Implement Custom Summary

Show Me

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=E1877.

The following example shows how to calculate a custom summary.

Assume that the ASPxPivotGrid control is bound to an "Invoices" table, which contains invoices information (product name, extended price, salesperson, etc). A field that displays the ratio of units cost over $50 is to be added.

In this example, a custom summary is calculated against the "Unit Price" field. Its PivotGridCustomTotalBase.SummaryType property is set to PivotSummaryType.Custom and the caption to "Percentage of units cost over $50". The PivotGridControl.CustomSummary event is handled to only count those records whose total sum exceeds $50. The ratio of these records to all the records is a custom summary value and, therefore, is assigned to the PivotGridCustomSummaryEventArgsBase.CustomValue parameter.
