无法检测上的keydown事件按Ctrl +快捷键，只要有一个只读的文本框，重点 [英] Can't detect a Ctrl + Key shortcut on keydown events whenever there's a readonly textbox with focus

问题描述

我想我通过自己解决了这个问题，但它回来困扰我的应用程序，使这里有云：

i thought i solved this problem by myself but it came back to haunt my application so here it goes:

我已经注册的形式与一对夫妇的残疾人和只读文本框下面的keydown事件处理程序，他们只对按键简单快捷方式：

i have the following keydown event handler registered in a form with a couple of disabled and readonly textboxes and they are only simple shortcuts for the buttons:

private void AccountViewForm_KeyDown(object sender, KeyEventArgs e)
    {
        //e.SuppressKeyPress = true;
        //e.Handled = true;
        if (Control.ModifierKeys == Keys.Control && e.KeyCode == Keys.E && !isInEditMode)
            btnEditMode_Click(sender, e);
        if (Control.ModifierKeys == Keys.Control && e.KeyCode == Keys.S && isInEditMode) btnEditMode_Click(sender, e);
        if (e.KeyCode == Keys.Escape) btnCancel_Click(sender, e);
        if (Control.ModifierKeys == Keys.Control && e.KeyCode == Keys.W) Close();
    }

的形式主要有preVIEW设置为true，但每当一个只读文本框具有焦点，并且我preSS按Ctrl + E我不能让Control.ModifierKeys == Keys.Control和e.Key code == Keys.E既如此在同一时间。什么是真正奇怪的是，按Ctrl + W的作品。任何人有任何想法，这到底是怎么回事？ ：（

the form has KeyPreview set to true but whenever a readonly textbox has focus and i press Ctrl + E i can't get "Control.ModifierKeys == Keys.Control" and "e.KeyCode == Keys.E" to be both true at the same time. What is really strange is that Ctrl + W works. Anyone has any idea what the hell is going on? :(

推荐答案

根据这个问题和的this 之一，它看起来像处理键盘快捷键的更普遍的方法是重写给ProcessCmdKey（）方法：

According to this question and this one, It looks like a more general way to handle keyboard shortcuts is to override the ProcessCmdKey() method:

protected override bool ProcessCmdKey(ref Message msg, Keys keyData) {
  if (keyData == (Keys.Control | Keys.F)) {
    MessageBox.Show("What the Ctrl+F?");
    return true;
  }
  return base.ProcessCmdKey(ref msg, keyData);
}

你有没有考虑过使用<大骨节病>替代 + <大骨节病>电子和<大骨节病>替代 + <大骨节病>取值，只是设置的助记符属性您按钮？这似乎很好地工作对我来说，它更容易建立起来。

Have you considered using Alt + E and Alt + S and just setting the mnemonic property for your buttons? That seems to work well for me, and it's easier to set up.
