ListBox controls are often used with data styling. See Data Templates Overview for a discussion of data styling.
ContentModel: A ListBox is an ItemsControl. For more information on the content model for ListBox, see ItemsControl Content Model.
This example shows how to create a ListBox using the Extensible Application Markup Language (XAML) and implement event handlers in C# or Microsoft Visual Basic to handle selection changes.
The ListBox in the following XAML example contains multiple list items. When the user selects one of the items, the event handler displays the name of the selected item in the TextBox.
<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>
void PrintText(object sender, SelectionChangedEventArgs args) { ListBoxItem lbi = ((sender as ListBox).SelectedItem as ListBoxItem); tb.Text = " You selected " + lbi.Content.ToString() + "."; }
