的WinForms文本框 - 使用Ctrl-Backspace键删除整个词 [英] Winforms Textbox - Using Ctrl-Backspace to Delete Whole Word

问题描述

我有其他控件中包含一个文本框，允许输入单行一个WinForms对话框。我想，让用户能够以preSS按Ctrl-Backspace键删除整个单词。这是不是与外的现成文本框的默认行为;我得到的长方形的角色，而不是删除的字。

I have a Winforms dialog that contains among other controls a TextBox that allows a single line of input. I would like to allow the user to be able to press Ctrl-Backspace to delete an entire word. This is not the default behaviour with the out-of-the-box TextBox; I get a rectangle character, rather than having the word deleted.

我已经确认了 ShortcutsEnabled 属性设置为真。

I have confirmed the ShortcutsEnabled property is set to True.

我也发现，我可以用一个RichTextBox，而不是一个TextBox得到我想要的行为。这里的问题是，RichTextBox的（境特别）的外观是从文本框的不同，我并不需要或想要的文字标记的能力。

I did find that I can use a RichTextBox rather than a TextBox to get the behaviour I want. The problem with this is that the apperance of the RichTextBox (border in particular) is different from that of the TextBox, and I don't need or want the ability to mark up text.

所以我的问题是如何最好地处理这种情况？是否有，我很想念文本框的一些财产？或者是它最好使用RichTextBox的，更新的外观，因此是一致的，而文字的禁用标记？

So my question is how to best handle this situation? Is there some property on the TextBox that I am missing? Or is it best to use the RichTextBox, update the appearance so it is consistent, and disable markup of the text?

我是比较快乐写code处理KeyDown和明确地重点preSS事件，如果没有更好的办法，但认为这是值得一试第一。

I am relatively happy to write the code to handle the KeyDown and KeyPress events explicity if there is no better way, but thought it was worth checking first.

推荐答案

我可以模拟按Ctrl + Backspace键发送按Ctrl + Shift +左键和Backspace到文本框。其效果是几乎相同的，而且也没有必要手动处理控制的文本。您可以使用此code ++实现的：

I would simulate Ctrl+Backspace by sending Ctrl+Shift+Left and Backspace to the TextBox. The effect is virtually the same, and there is no need to manually process control’s text. You can achieve it using this code:

class TextBoxEx : TextBox
{
    protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
    {
        if (keyData == (Keys.Control | Keys.Back))
        {
            SendKeys.SendWait("^+{LEFT}{BACKSPACE}");
            return true;
        }
        return base.ProcessCmdKey(ref msg, keyData);
    }
}

您还可以修改app.config文件，强制SendKey类使用发送键的较新的方法：

You can also modify the app.config file to force the SendKey class to use newer method of sending keys:

<configuration>
  <appSettings>
    <add key="SendKeys" value="SendInput" />
  </appSettings>
</configuration>
