ListView.MultiSelect Property

Gets or sets a value indicating whether multiple items can be selected.

[Visual Basic]
Public Property MultiSelect As Boolean
public bool MultiSelect {get; set;}
public: __property bool get_MultiSelect();
public: __property void set_MultiSelect(bool);
public function get MultiSelect() : Boolean;
public function set MultiSelect(Boolean);

Property Value

true if multiple items in the control can be selected at one time; otherwise, false. The default is true.


When the MultiSelect property is set to true, multiple items can be selected in the ListView control. To select multiple items, the user must hold down the CTRL key while clicking the items to select. Consecutive items can be selected by clicking the first item to select and then, while holding down the SHIFT key, clicking the last item to select. You can use the multiselection feature to select multiple items in the ListView control and perform an operation on all the items selected. For example, the user could select multiple items and then right-click a selected item to display a shortcut menu that displays a set of tasks that can be performed on the selected items.

To determine which items are selected in the ListView control, use the SelectedItems property. The SelectedItems property allows you to access the ListView.SelectedListViewItemCollection that contains a list of the selected items. If you want the index positions in the ListView.ListViewItemCollection instead of the items, you can use the SelectedIndices property to access the ListView.SelectedIndexCollection.

If you do not want to allow multiple selections in the ListView, yet still want to offer the user a way for multiple items to be chosen, you can display check boxes by setting the CheckBoxes property to true.


[Visual Basic, C#] The following code example demonstrates initializing a ListView control to contain check boxes. It also demonstrates using the MultiSelect property. To run this example paste the following code in a form containing a ListView named ListView1. Call the InititalizeListView method from the form's constructor or Load method.

[Visual Basic] 
Private Sub InitializeListView()
    Me.ListView1 = New System.Windows.Forms.ListView

    ' Set properties such as BackColor, Location and Size
    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.Size = New System.Drawing.Size(292, 130)
    Me.ListView1.View = System.Windows.Forms.View.Details
    Me.ListView1.HideSelection = False

    ' Allow user to select multiple items.
    Me.ListView1.MultiSelect = True

    ' Show check boxes in the ListView.
    Me.ListView1.CheckBoxes = True

    'Set the column headers and populate the columns.
    ListView1.HeaderStyle = ColumnHeaderStyle.Nonclickable
    Dim columnHeader1 As New ColumnHeader
    With columnHeader1
        .Text = "Breakfast Choices"
        .TextAlign = HorizontalAlignment.Left
        .Width = 146
    End With
    Dim columnHeader2 As New ColumnHeader
    With columnHeader2
        .Text = "Price Each"
        .TextAlign = HorizontalAlignment.Center
        .Width = 142
    End With
    Dim foodList() As String = New String() {"Juice", "Coffee", _
        "Cereal & Milk", "Fruit Plate", "Toast & Jelly", _
        "Bagel & Cream Cheese"}

    Dim foodPrice() As String = New String() {"1.09", "1.09", "2.19", _
        "2.79", "2.09", "2.69"}
    Dim count As Integer

    ' Members are added one at a time, so call BeginUpdate to ensure 
    ' the list is painted only once, rather than as each list item is added.

    For count = 0 To foodList.Length - 1
        Dim listItem As New ListViewItem(foodList(count))

    'Call EndUpdate when you finish adding items to the ListView.
End Sub

private void InitializeListView()
    this.ListView1 = new System.Windows.Forms.ListView();

    // Set properties such as BackColor and DockStyle and Location.
    this.ListView1.BackColor = System.Drawing.SystemColors.Control;
    this.ListView1.Dock = System.Windows.Forms.DockStyle.Top;
    this.ListView1.Location = new System.Drawing.Point(0, 0);
    this.ListView1.Size = new System.Drawing.Size(292, 130);
    this.ListView1.View = System.Windows.Forms.View.Details;
    this.ListView1.HideSelection = false;

    // Allow the user to select multiple items.
    this.ListView1.MultiSelect = true;

    // Show CheckBoxes in the ListView.
    this.ListView1.CheckBoxes = true;
    //Set the column headers and populate the columns.
    ListView1.HeaderStyle = ColumnHeaderStyle.Nonclickable;
    ColumnHeader columnHeader1 = new ColumnHeader();
    columnHeader1.Text = "Breakfast Choices";
    columnHeader1.TextAlign = HorizontalAlignment.Left;
    columnHeader1.Width = 146;

    ColumnHeader columnHeader2 = new ColumnHeader();
    columnHeader2.Text = "Price Each";
    columnHeader2.TextAlign = HorizontalAlignment.Center;
    columnHeader2.Width = 142;


    string[] foodList = new string[]{"Juice", "Coffee", 
        "Cereal & Milk", "Fruit Plate", "Toast & Jelly", 
        "Bagel & Cream Cheese"};

    string[] foodPrice = new string[]{"1.09", "1.09", "2.19", 
        "2.79", "2.09", "2.69"};
    int count;

    // Members are added one at a time, so call BeginUpdate to ensure 
    // the list is painted only once, rather than as each list item is added.

    for(count = 0; count < foodList.Length; count++)
        ListViewItem listItem = new ListViewItem(foodList[count]);

    //Call EndUpdate when you finish adding items to the ListView.
