Content Model: ListBox is a ItemsControl. Its content properties are Items and ItemsSource. For more information on the content model for ListBox, see Controls Content Model Overview.
The ListBox is a control that contains a collection of items. More than one item in a ListBox is visible, unlike the ComboBox, which has only the selected item visible unless the IsDropDownOpen property is true. The SelectionMode property determines whether more than one item in the ListBox is selectable at a time.
The SelectionMode property determines how many items a user can select at one time. You can set the property to Single (the default), Multiple, or Extended. The following table described the behavior of these enumeration values.
Value | Description |
|---|
Single
| The user can select only one item at a time. |
Multiple
| The user can select multiple items without holding down a modifier key. |
Extended
| The user can select multiple consecutive items while holding down the SHIFT key or non-consecutive items by holding down the CTRL key and clicking the items. |
ListBox controls are often used with data binding. For more information, see Data Binding Overview.
Displaying a large number of items may cause performance issues. See Optimizing Performance: Controls for more information.
Dependency properties for this control might be set by the control’s default style. If a property is set by a default style, the property might change from its default value when the control appears in the application. The default style is determined by which desktop theme is used when the application is running. For more information, see Themes.
The following example creates a ListBox and subscribes to the SelectionChanged event.
<TextBox Name="tb" Width="140" Height="30"></TextBox>
<ListBox Name="lb" Width="100" Height="55" SelectionChanged="PrintText" SelectionMode="Single">
<ListBoxItem>Item 1</ListBoxItem>
<ListBoxItem>Item 2</ListBoxItem>
<ListBoxItem>Item 3</ListBoxItem>
<ListBoxItem>Item 4</ListBoxItem>
<ListBoxItem>Item 5</ListBoxItem>
<ListBoxItem>Item 6</ListBoxItem>
<ListBoxItem>Item 7</ListBoxItem>
<ListBoxItem>Item 8</ListBoxItem>
<ListBoxItem>Item 9</ListBoxItem>
<ListBoxItem>Item 10</ListBoxItem>
</ListBox>
Private Sub PrintText(ByVal sender As Object, ByVal e As SelectionChangedEventArgs)
Dim lbsender As ListBox

tb.Text = " You selected " & li.Content.ToString & "."
End Sub
void PrintText(object sender, SelectionChangedEventArgs args)
{
ListBoxItem lbi = ((sender as ListBox).SelectedItem as ListBoxItem);
tb.Text = " You selected " + lbi.Content.ToString() + ".";
