<p>You can use the <xref href="C1.WPF.FlexReport.Field.HideDuplicates" data-throw-if-not-resolved="false"></xref> property to hide a field on a report 

when its value is the same as in the preceding record.

For example, on a report listing suppliers and their products, each supplier's name can appear once for each group of products, rather than once for each product.
