如何在wpf中清除另一个xaml文件的文本字段？ [英] how to clear the text fields of another xaml file in wpf ?

问题描述

我有2个表单，LoginInfo和CreditCardInfo。



我想在用户点击Loginfo中的OK按钮后清除CreditCardInfo中的字段。我怎么能这样做？

I have 2 forms, LoginInfo and CreditCardInfo.

I would like to clear the fields from CreditCardInfo once the user clicks the OK button that resides in Loginfo. How can I do this ?

推荐答案

你有权使用医生吗？如果是，请在用户单击按钮时使用介体从loginfo屏幕向CrediatCardInfo屏幕发送消息。 

do you have access to a medaitor. If yes, use the mediator to send a message from the loginfo screen to the CrediatCardInfo screen when a user clicks the button. 

信用卡屏幕应该"处理"消息并清除字段。

The Creditcard screen should "handle" the message and clear the fields.

如果您使用mvvm灯，棱镜那里已有一个，否则试试这个 -
