Web浏览器控件：如何捕获文档事件？ [英] Web browser control: How to capture document events?

问题描述

我使用WPF的WebBrowser控件加载一个简单的网页。在这个页面我有一个锚或一个按钮。我想捕获按钮的点击事件在我的应用程序的code的后面（即C＃）。

I am using WPF's WebBrowser control to load a simple web page. On this page I have an anchor or a button. I want to capture the click event of that button in my application's code behind (i.e. in C#).

时有WebBrowser控件捕捉点击加载页面的元素事件的方法吗？

Is there are a way for the WebBrowser control to capture click events on the loaded page's elements?

此外，是否有可能进行沟通事件触发​​页面和web浏览器之间的数据？上述所有的应该是可能的是吗？

In addition, is it possible to communicate event triggered data between the page and the WebBrowser? All of the above should be possible am I right?
