推荐答案

您可以将Label的updatesourcetrigger设置为explisit，并手动决定何时在第二个选项卡上显示更改。默认情况下，它设置为OnPropertyChange，这就是在您的属性更改后它发生变化的原因。

You can set updatesourcetrigger for your Label as explisit and manually decide when to Show changes on the second tab. By default it is set to OnPropertyChange, that's why it is changing after your property was changed.

<label x:name = "lblname" content= {Binding Text, ElementName = txtname, UpdateSourceTrigger=PropertyChanged} />
