是否可以将两个源属性绑定到一个控件属性？ [英] Is it possible to bind two source properties to one control property?

问题描述

使用WPF，可以通过单向绑定将两个源属性绑定到一个控件属性（即textbox.text）？我想让用户在文本框中输入一个值，并将该值推送到源数据文本中的两个不同的属性。我的解决方法是创建一个虚拟属性，并让setter手动设置两个值。

Using WPF, is it possible to bind two source properties, via one-way binding, to one control property (ie textbox.text)?? I'd like to have the user input a value in a textbox and have that value pushed to two different properties in the source datacontext. My workaround is to create a dummy property and have the setter set the two values manually.

推荐答案

代理，如本博客文章中所述：

You could use kind of binding-proxy, as described in this blog post:

然后只需按照这些步骤，例如：

Then just follow these steps for example:

1. 使用x定义一个TextBox：Name = tb


2. 将TextBox.Text绑定到Prop1

使用In ={Binding Text，ElementName = tb}添加代理元素，Out ={Binding Prop2}（不在TextBox内）

这样一来，您可以将Prop1和Prop2与tb.Text同步。

This way, you will have Prop1 and Prop2 synchronized with tb.Text.
