This document describes how to evaluate custom summaries using report scripts within the End-User Report Designer.

Note

With Expressions Bindings , calculation of custom summaries is no longer available. You are encouraged to write a custom expression with operators, functions, and constants, as described in the following help topic: Expression Language. For additional examples refer to the following help section: Calculate Summaries.

Important

Report scripts are not secure and are disabled by default. We recommend that you use expression bindings instead.

Create a new XRLabel, which is the only report control that supports custom summary calculations.
Set the XRSummary.Func property to SummaryFunc.Custom and assign custom scripts to the appropriate event handlers of the object returned by the XRLabel.Scripts property.
