How do I allow CTRL-V (Paste) on a Winforms Textbox?
提问by Neil N
I have several textboxes on a windows form.
我在 Windows 窗体上有几个文本框。
I can't paste text into any of them using CTRL-V, though I can still right click and select paste. This is pretty annoying.
我无法使用 CTRL-V 将文本粘贴到其中任何一个中，但我仍然可以右键单击并选择粘贴。这很烦人。
I have tried this with the form's KeyPreview as both true and false. TextBox.ShortcutsEnabled is also true.
我已经用表单的 KeyPreview 尝试了这个，无论是对还是错。TextBox.ShortcutsEnabled 也是如此。

Check to see if you have a menu on the form with a shortcut for Ctrl-V.
检查表单上是否有带有 Ctrl-V 快捷方式的菜单。

The code you posted has nothing to do with your Ctrl + V problem, that is for certain. Not much else I can tell you unless you post some more code.
您发布的代码与您的 Ctrl + V 问题无关，这是肯定的。除非你发布更多代码，否则我不能告诉你更多。
Special code should not be needed for Ctrl + V, but one guess I have is to make sure you have YourTextBoxId.ShortcutsEnabledset to True.
不应需要特殊的代码，按Ctrl + V，但一想我已经是确保你已经YourTextBoxId.ShortcutsEnabled设置True。

The following code should help:
以下代码应该会有所帮助：
private void textBox1_KeyUp(object sender, KeyEventArgs e) {
if (e.KeyData == (Keys.Control | Keys.V))
(sender as TextBox).Paste();
}

Yeah.. I know this is answered but I thought I'd throw my 2cents in just for fun. I also had a similar problem. Setting the TextBox.ShortcutsEnabled value to True did nothing for me. I was surprised to see the note left by Microsoft here: http://msdn.microsoft.com/en-us/library/system.windows.forms.textboxbase.shortcutsenabled.aspxregarding this issue. Quite interesting to say the least.
是的..我知道这是回答，但我想我会为了好玩而投入我的 2 美分。我也有类似的问题。将 TextBox.ShortcutsEnabled 值设置为 True 对我没有任何作用。我很惊讶地看到微软在这里留下的注释：http: //msdn.microsoft.com/en-us/library/system.windows.forms.textboxbase.shortcutsenabled.aspx关于这个问题。至少可以说很有趣。
Given that, I just implemented the functionality through the key even handlers as indicated in the post by Webleeuw.
鉴于此，我只是通过 Webleeuw 的帖子中指出的关键偶数处理程序实现了该功能。

I was also going thru with the same problem. after a lot of googling finally I found the solution. It is because in the aplliciation ctrl+v shortcut was already defined(Edit menu-> Paste). After removing this...it work fine for me....Hope that it helps....
我也遇到了同样的问题。经过大量的谷歌搜索，我终于找到了解决方案。这是因为在应用程序中已经定义了 ctrl+v 快捷方式（编辑菜单-> 粘贴）。删除它后......它对我来说很好......希望它有帮助......

The TextBox control does not support the CTRL+Ashortcut key when the Multiline property value is true.
当 Multiline 属性值为 true 时，TextBox 控件不支持CTRL+A快捷键。

You can comment already assigned same shortcut to other control, from designer.cs/.vb form of your form. In my case I solved it for menu in following way
您可以从表单的designer.cs/.vb 表单中注释已分配给其他控件的相同快捷方式。在我的情况下，我通过以下方式解决了菜单
//this.copyToolStripMenuItem.ShortcutKeys = ((System.Windows.Forms.Keys)
((System.Windows.Forms.Keys.Control | System.Windows.Forms.Keys.C)));

Go to properties for the control:
转到控件的属性：
Properties>Behaviour>Shortcuts Enabled = true
属性>行为>快捷方式已启用 = true
job done - will now accept default windows shortcut strokes for this control
工作完成 - 现在将接受此控件的默认 Windows 快捷方式
