ListView.SelectedItems Property

Gets the items that are selected in the control.

[Visual Basic]
Public ReadOnly Property SelectedItems As _
   ListView.SelectedListViewItemCollection
[C#]
public ListView.SelectedListViewItemCollection SelectedItems {get;}
[C++]
public: __property ListView.SelectedListViewItemCollection*
   get_SelectedItems();
[JScript]
public function get SelectedItems() :
   ListView.SelectedListViewItemCollection;

Property Value

A ListView.SelectedListViewItemCollection that contains the items that are selected in the control. If no items are currently selected, an empty ListView.SelectedListViewItemCollection is returned.

Remarks

When the MultiSelect property is set to true, this property returns a collection containing the items that are selected in the ListView. For a single-selection ListView, this property returns a collection containing the only selected item in the ListView. For more information on the tasks that can be performed with the items in the collection, see ListView.SelectedListViewItemCollection.

If you want to obtain a collection of the index positions within the ListView.ListViewItemCollection of the items that are selected in the ListView control, instead of the items that are selected, use the SelectedIndices property.

Example

[Visual Basic, C#] The following code example demonstrates using the SelectedItems, SelectedIndexChanged event, and HeaderStyle members and the System.Windows.Forms.SelectedListViewItemCollection class. To run this example paste the following code in a form that contains a ListView object named ListView1 and a TextBox named TextBox1. Call the InitializeListView method from the form's constructor or Load method. This example assumes the event-handling method is correctly associated with the SelectedIndexChanged event.

[Visual Basic] 
' This method adds two columns to the ListView, setting the Text 
' and TextAlign, and Width properties of each ColumnHeader.  The 
' HeaderStyle property is set to NonClickable since the ColumnClick 
' event is not handled.  Finally the method adds ListViewItems and 
' SubItems to each column.
Private Sub InitializeListView()
    Me.ListView1 = New System.Windows.Forms.ListView
    Me.ListView1.BackColor = System.Drawing.SystemColors.Control
    Me.ListView1.Dock = System.Windows.Forms.DockStyle.Top
    Me.ListView1.Location = New System.Drawing.Point(0, 0)
    Me.ListView1.Name = "ListView1"
    Me.ListView1.Size = New System.Drawing.Size(292, 130)
    Me.ListView1.TabIndex = 0
    Me.ListView1.View = System.Windows.Forms.View.Details
    Me.ListView1.MultiSelect = True
    Me.ListView1.HideSelection = False
    ListView1.HeaderStyle = ColumnHeaderStyle.Nonclickable
    Dim columnHeader1 As New ColumnHeader
    With columnHeader1
        .Text = "Breakfast Item"
        .TextAlign = HorizontalAlignment.Left
        .Width = 146
    End With
    Dim columnHeader2 As New ColumnHeader
    With columnHeader2
        .Text = "Price Each"
        .TextAlign = HorizontalAlignment.Center
        .Width = 142
    End With

    Me.ListView1.Columns.Add(columnHeader2)

    Dim foodPrice() As String = New String() {"1.09", "1.09", _
        "2.19", "2.49", "1.49", "1.49"}
    Dim count As Integer
    For count = 0 To foodList.Length - 1
        Dim listItem As New ListViewItem(foodList(count))
        listItem.SubItems.Add(foodPrice(count))
        ListView1.Items.Add(listItem)
