关于按键代码检测的keydown事件 [英] about keydown event for key code detect

问题描述

我有一个窗口窗体，它包含多个具有"Panel"类型的控件，
现在，我将KeyDown事件添加到此表单和控件中.

我发现表单的keydown可以提供向左/向右/向上/向下的按键检测，
但是，控件(面板)的keydown事件将不提供向左/向右/向上/向下
密钥检测，对吗?如果是，如何获得左/右/上/下
控制键按下事件的键代码?如果不是，那可能是什么问题?

感谢您在此问题上的全力支持.

I have a window form, and it includes several control with ''Panel'' type,
now I add KeyDown event to this form and control.

I found that the keydown of form can provide left/right/up/down key detect,
however, the keydown event of control (Panel) will not provide left/right/up/down
key detect, is that right ? If yes, how can I get the left/right/up/down
key code for control keydown event ? If not, what''s wrong it could be ?

Thanks of your fully support on this issue.

推荐答案

您好，

我认为您正在为控件(面板)搜索PreviewKeyDown-Event.

Hi,

I think you''re searching for PreviewKeyDown-Event for your Control (your panel).

private void panel1_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
        {
            if (e.KeyCode == Keys.Left)
            {
                //do something
            }
        }

致以最诚挚的问候

With Best Regards
