The ListBox control enables you to display a list of items to the user that the user can select by clicking. A ListBox control can provide single or multiple selections using the SelectionMode property. The ListBox also provides the MultiColumn property to enable the display of items in columns instead of a straight vertical list of items. With this, the control can display more visible items and the user no longer needs to scroll to an item.

Typically, Windows handles the task of drawing the items to display in the ListBox. You can use the DrawMode property, and handle the MeasureItem and DrawItem events so you can override the automatic drawing that Windows provides and draw the items yourself. You can use owner-drawn ListBox controls to display variable-height items, images, or a different color or font for the text of each item in the list. The HorizontalExtent property, GetItemHeight, and GetItemRectangle also help you draw your own items.

In addition to display and selection functionality, the ListBox also provides features that enable you to efficiently add items to the ListBox and to find text within the items of the list. The BeginUpdate and EndUpdate methods enable you to add a large number of items to the ListBox without the control being repainted each time an item is added to the list. The FindString and FindStringExact methods enable you to search for an item in the list that contains a specific search string.

The Items, SelectedItems, and SelectedIndices properties provide access to the three collections that are used by the ListBox. The following table outlines the three collections used by the ListBox and their use within the control.

Collection class

Use within the ListBox

ListBox.ObjectCollection

Contains all items contained in the ListBox control.

ListBox.SelectedObjectCollection

Contains a collection of the selected items which is a subset of the items contained in the ListBox control.

ListBox.SelectedIndexCollection

Contains a collection of the selected indexes, which is a subset of the indexes of the ListBox.ObjectCollection. These indexes specify items that are selected.

The following three examples show the three indexed collections that the ListBox class supports.

The following table shows an example of how the ListBox.ObjectCollection stores the items of the ListBox as well as their selection state within an example ListBox.

The Add method of the ListBox.ObjectCollection class enables you to add items to the ListBox. The Add method can accept any object when adding a member to the ListBox. When an object is being added to the ListBox, the control uses the text defined in the ToString method of the object unless a member name within the object is specified in the DisplayMember property. In addition to adding items using the Add method of the ListBox.ObjectCollection class you can also add items using the DataSource property of the ListControl class.

System_CAPS_noteNote

If you have a ListBox, ComboBox, or CheckedListBox on a base Windows form and want to modify the string collections of those controls in a derived Windows form, the string collections of those controls in the base Windows form must be empty. If the string collections are not empty, they become read-only when you derive another Windows form.

The following code example demonstrates how to create a ListBox control that displays multiple items in columns and can have more than one item selected in the control's list. The code for the example adds 50 items to the ListBox using the Add method of the ListBox.ObjectCollection class and then selects three items from the list using the SetSelected method. The code then displays values from the ListBox.SelectedObjectCollection collection, through the SelectedItems property, and the ListBox.SelectedIndexCollection, through the SelectedIndices property. This example requires that the code is located in and called from a Form.

Private Sub button1_Click(sender As Object, e As System.EventArgs)
    ' Create an instance of the ListBox.
    Dim listBox1 As New ListBox()
    ' Set the size and location of the ListBox.
    listBox1.Size = New System.Drawing.Size(200, 100)
    listBox1.Location = New System.Drawing.Point(10, 10)
    ' Add the ListBox to the form.
    Me.Controls.Add(listBox1)
    ' Set the ListBox to display items in multiple columns.
    listBox1.MultiColumn = True
    ' Set the selection mode to multiple and extended.
    listBox1.SelectionMode = SelectionMode.MultiExtended

    ' Shutdown the painting of the ListBox as items are added.
    listBox1.BeginUpdate()
    ' Loop through and add 50 items to the ListBox.
    Dim x As Integer
    For x = 1 To 50
        listBox1.Items.Add("Item " & x.ToString())
    Next x
    ' Allow the ListBox to repaint and display the new items.
    listBox1.EndUpdate()

    ' Select three items from the ListBox.
    listBox1.SetSelected(1, True)
    listBox1.SetSelected(3, True)
    listBox1.SetSelected(5, True)

    ' Display the second selected item in the ListBox to the console.
    System.Diagnostics.Debug.WriteLine(listBox1.SelectedItems(1).ToString())
    ' Display the index of the first selected item in the ListBox.
    System.Diagnostics.Debug.WriteLine(listBox1.SelectedIndices(0).ToString())
End Sub
