禁用复制并粘贴在datagridview中 [英] disable copy and paste in datagridview

问题描述

我是.net的初学者.这可能是一个愚蠢的问题.我想禁用 ctrl + c 和 ctrl + v 键盘快捷键.

I am a beginner in .net. This could be a silly question. I want to disable ctrl + c and ctrl + v keyboard shortcuts.

在这里问之前，我尝试了以下代码 link1 和链接2 (不起作用)

Before asking here I tried these codes link1 and link2 (not working)

private void dgvMain_CellEndEdit(object sender, DataGridViewCellEventArgs e)
    {
        this.dgvMain.ClipboardCopyMode = DataGridViewClipboardCopyMode.EnableWithoutHeaderText;
    }

    private void dgvMain_CellBeginEdit(object sender, DataGridViewCellCancelEventArgs e)
    {
        this.dgvMain.ClipboardCopyMode = DataGridViewClipboardCopyMode.Disable;
    }

还有

this.dgvMain.ClipboardCopyMode = DataGridViewClipboardCopyMode.Disable;

dgvMain是datagridview
我可能在这里错过了一些东西.

dgvMain is datagridview
I maybe missing something here.

我已更改的datagridview的属性是:

The properties for my datagridview which I have altered are:

AllowUserToResizeColumns      -- False
AllowUserToResizeRows         -- False
ClipboardCopyMode             -- disable
ColumnsHeadersHeightSizeMode  -- AutoSize
Dock                          -- Fill
ReadOnly                      -- True   
TabStop                       -- False

请帮助
预先感谢.

Please help
Thanks in Advance.

推荐答案

您不会拼写出不起作用的部分，因此我只能猜测您是指网格的TextBox部分.

You don't spell out the not-working part, so I can only guess that you are referring to the TextBox part of the grid.

仅具有ClipboardCopyMode = Disable应该足够了，但是如果单元格的TextBox处于编辑模式，则该属性将被忽略.您必须自己禁用按键和ContextMenu:

It should be enough to just have ClipboardCopyMode = Disable but if the TextBox of the cell is in edit mode, that property gets ignored. You would have to disable the keys and the ContextMenu yourself:

示例:

public Form1()
{
  InitializeComponent();
  dgvMain.ClipboardCopyMode = DataGridViewClipboardCopyMode.Disable;
  dgvMain.EditingControlShowing += dgvMain_EditingControlShowing;
}

void dgvMain_EditingControlShowing(object sender,
                                   DataGridViewEditingControlShowingEventArgs e)
{
  TextBox tb = e.Control as TextBox;
  if (tb != null) {
    tb.ContextMenuStrip = new ContextMenuStrip();
    tb.KeyDown -= TextBox_KeyDown;
    tb.KeyDown += TextBox_KeyDown;
  }
}

void TextBox_KeyDown(object sender, KeyEventArgs e)
{
  if (e.Control && (e.KeyCode == Keys.C | e.KeyCode == Keys.V)) {
    e.SuppressKeyPress = true;
  }
}
