Gets or sets a value indicating whether an event was handled. If it was handled, the custom summary value is assigned to the SummaryGetResultEventArgs.Result property.
true if the custom summary value is calculated; otherwise, false.
Use the SummaryGetResultEventArgs.Result and Handled properties to define a custom summary value on the XRLabel.SummaryGetResult event. After the summary value is calculated, it should be assigned to the SummaryGetResultEventArgs.Result property. In addition, you need to set the Handled property to true. Note that if the Handled property is set to false, then the custom summary value remains undetermined and is set to null (Nothing in Visual Basic).
