同样,如果您看到文本绑定源为Sing的“Textblock”,这就是我需要的文本值。有一个默认的选择行为,这取决于项源是什么(所使用的类型)。因此,是您的模型
类的类型,因此您可以从所选模型中获取的文本
例如,您的模型类名为model
,然后您可以使用以下代码获取文本
private void ListBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
var selected = AlbumSongList.SelectedItem as Model;
Debug.WriteLine("You have selected the song: Song Number is {0}, and Song is {1}",
selected.SongNumber, selected.Song);
}
你能提供专辑歌曲列表的详细信息吗?我已经更新了,如果你能帮忙的话,非常感谢,对我来说非常有用。你是个明星
