在处理WebBrowser控件的关键事件 [英] Handling key events on WebBrowser control

问题描述

我现在用的是 web浏览器在C＃应用程序控制，并希望处理所有按键事件，而 web浏览器有的焦点，无论什么各个内容要素（输入字段，链接等）被​​聚焦。我试图只是一个事件处理程序添加到浏览器控件的KeyDown 事件，但这不起作用。我不想明确地将一个处理器连接到每一个聚焦的的HtmlElement 。

I am using the WebBrowser control in a C# application and want to handle all key events while the WebBrowser has the focus, regardless what individual content element (input field, link, etc.) is focused. I tried to simply add an event handler to browser controls KeyDown event, but this does not work. I don't want to explicitly hook a handler to each focusable HtmlElement.

我怎样才能收到所有重要事件的 的它们传递到浏览器或其内容元素之前？

How can I receive all key events before they are passed to the browser or its content elements?

您的<一个href=\"http://msdn.microsoft.com/en-us/library/system.windows.forms.control.$p$pviewkeydown.aspx\">$p$pviewKeyDown事件只是把它挂起来。

you have the PreviewKeyDown event just hook it up.

private void wb_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
{
    // your code handling the keys here, like:
    if (e.Control && e.KeyCode == Keys.C)
    {
        // Do something funny!
    }
}
