[英]Is it possible to bind two source properties to one control property?
Using WPF, is it possible to bind two source properties, via one-way binding, to one control property (ie textbox.text)?? 使用WPF,是否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)? 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.
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上下文中的两个不同属性。 My workaround is to create a dummy property and have the setter set the two values manually.
我的解决方法是创建一个虚拟属性,并让设置器手动设置两个值。
You need to use a MultiBinding with a IMultiValueConverter . 您需要将MultiBinding与IMultiValueConverter一起使用。 See the example in the documentation
请参阅文档中的示例
You could use kind of binding-proxy, as described in this blog post: 您可以使用一种绑定代理,如此博客文章所述:

Then just follow these steps for example: 然后,请按照以下步骤操作:
This way, you will have Prop1 and Prop2 synchronized with tb.Text. 这样,您将使Prop1和Prop2与tb.Text同步。
