推荐答案

您可以将内容项转换为INotifyPropertyChanged，然后侦听当StringValue属性更改时.然后获取StringValue的值，这将是在文本框"控件中输入的文本.

You can cast the content item to INotifyPropertyChanged and then listen for when the StringValue property changes. Then get the value of StringValue and that will be the text that was entered into the Text Box control.
