You make two taks: 1.- Aggregate the GroupDescriptions: var view = CollectionViewSource.GetDefaultView(estadoEventos); view.GroupDescriptions.Add( new PropertyGroupDescription( "NamePropertyToGroup" )); 2.- Modify the GroupStyle of ListBox: ListView ... > ListView.GroupStyle > GroupStyle > GroupStyle.ContainerStyle > Style TargetType = "{x:Type GroupItem}" > Setter Property = "Margin" Value = "0,0,0,5" /> Setter Property = "Template" > Setter.Value > ControlTemplate TargetType = "{x:Type GroupItem}" > Expander IsExpanded = "False" BorderBrush = "#FFA4B97F" BorderThickness = "2,2,2,2" > Expander.Header > DockPanel > TextBlock HorizontalAlignment = "Center" VerticalAlignment = "Center" FontWeight = "Bold" Text = "{Binding Name, StringFormat=dd/MM/yyyy}" Margin = "5,0,0,0" Width = "100" /> TextBlock HorizontalAlignment = "Center" VerticalAlignment = "Center" FontWeight = "Bold" Text = "{Binding ItemCount}" /> DockPanel > Expander.Header > ItemsPresenter /> Expander > ControlTemplate > Setter.Value > Setter > Style > GroupStyle.ContainerStyle > GroupStyle > ListView.GroupStyle > ListView > It appeared very much code, but it is simple.
