事件类型

示例

从建议列表中选择书籍时，将 的文本区域 AutoSuggestBox 设置为书籍的标题：

<AutoSuggestBox  
    ItemsSource="{x:Bind Books}"
    SuggestionChosen="AutoSuggestBox_SuggestionChosen" 
    UpdateTextOnSelect="True" />

private void AutoSuggestBox_SuggestionChosen(AutoSuggestBox sender, AutoSuggestBoxSuggestionChosenEventArgs args)
{
    var book = args.SelectedItem as Book;
    sender.Text = book.Title;
}

注解

如果要在控件的可编辑部分显示信息，请响应此事件。 选择建议时更新文本的另一种方法是使用 TextMemberPath 属性。
