如何在Windows Phone页面上强制绑定更新？ [英] How to force the binding update on Windows Phone Page?

问题描述

我有一个Windwos Phone页面，上面有多个TextBox控件。 TextBox控件是TwoWay绑定到类。我有一个ApplicationBar按钮 - "保存"，它会将类信息保存到IsolatedStorage。

I have a Windwos Phone page with multiple TextBox controls on it. The TextBox controls are TwoWay binded to a class. I have an ApplicationBar button - "Save", that will save the class info into IsolatedStorage.

当我将数据输入TextBox时，如果光标位于TextBox上;我按下"保存"按钮按钮，这最后一个TextBox不会将其内容更新到类中。如果我首先将焦点更改为另一个控件，则数据会正确更新为
类。

As I input data into the TextBoxes, if the cursor is on a TextBox and I press the "Save" button, this last TextBox will not update its content into the class. If I first change the focus to another control, the data is updated correctly into the class.

是否可以强制所有TextBox更新类？

Any way to force all the TextBox to update the class?

推荐答案

听起来好像没有"支持"绑定文本框的属性和/或没有INPC或Dependencyproperty实现。 为了使双向绑定工作，必须向WPF发送某种通知，只有两种方法可以实现。 
DependencyProperty（我最喜欢的）和INotifyPropertyChanged接口实现！

It sounds as if there is no "Backing" property to the bound textbox and or there is no INPC or Dependencyproperty implementation.  In order for two-way binding to work there must be some sort of notification to WPF, there are only two ways to do it.  DependencyProperty (my favorite) and INotifyPropertyChanged interface implementation!
