Public Property HideDuplicates As String

public string HideDuplicates {get; set;}

Property Value

A String containing the name of a grouping or data set within which the item is hidden when the value of the expression associated with the report item is the same as the preceding instance.

The value of HiddenDuplicates is the name of a grouping or data set over which to apply the hiding. Each time a new instance of that group is encountered, the first instance of this report item is not hidden. Rows on a previous page are ignored for the purposes of hiding duplicates. If the textbox is in a table or matrix cell, only the text is hidden. The textbox remains to provide background and border for the cell.

This property is ignored in matrix subtotals
