Gets or sets a value controlling whether the text should not be displayed when the value of the expression associated with the report item is the same as the preceding visible instance.

The value of this property is the name of a containing group (other than the current group) or data set over which to apply the hiding. Each time a new instance of that group is encountered, the first visible instance of this report item will not be hidden. Rows on a previous page are ignored for the purposes of hiding duplicates.

If the current textbox is in a Tablix cell, only the text will be omitted. The text box will remain to provide background and border for the cell. Outside of a tablix cell, the background and borders are omitted as well. Ignored unless the text box contains only one TextRun.
