在WPF中创建文本框事件? [英] Create a textbox event in WPF?

问题描述

我想在我的窗口中有一个文本框，有人可以在其中输入内容，然后当他们按Enter键时，它会在屏幕上生成某些内容，例如，其中包含该文本的小框.是否可以为文本框创建事件或命令，并将该文本框的text属性绑定到其生成的内容?

谢谢.

I want to have a textbox in my window where someone can type something into it and when they hit enter, it generates something on the screen, say, a small box with that text in it. Is it possible to create and event or command for a textbox and have that textbox''s text property bound to what it generates?

Thanks.

你好，

您可以使用以下提示以更简单的方式完成此操作:

我想您是在谈论双向绑定.
参见此处.

I guess you are talking about two-way binding.

我通过创建自己的TextBox类(称为CommandTextBox)解决了这个问题，该类注册了3个依赖项属性:command，commandParameter和commandTarget.

I solved this problem by creating my own TextBox class, called CommandTextBox which registers 3 Dependency properties: command, commandParameter, and commandTarget.
