Use the Bold, Italic, Underline and StrikeOut properties to apply different font attributes to the group. Use the Caption property to display different parts of the caption using HTML format. Use the Font property to specify the control's font. Use the StrikeOut property to specify whether the item's font is displayed with a horizontal line through it. Use the <s> HTML tag to specify parts of group's caption that should appear in strikeout, if CaptionFormat property is exHTML.

Private Sub ListBar1_AddGroup(ByVal Group As EXLISTBARLibCtl.IGroup)
    With Group
        .StrikeOut = True
    End With
End Sub

	group.SetStrikeOut( TRUE );
}

        .StrikeOut = True
    End With
End Sub

The following C# sample specify that all groups should appear in strikeout:
