我正在开发一个C#windows应用程序,并希望在DataGridView中复制一行并将其粘贴到一个新行中.我怎么能做到这一点?我正在使用.net framework 3.5.
能否请您提供一些想法或一些代码,以表明我如何实现这一目标?
我找到了一个帖子,其中包含将值从剪贴板粘贴到DataGridView中的代码.
我正在谷歌搜索如何从剪贴板粘贴到C#中的DataGridView,一个信息,从Excel复制,并没有找到完整的答案.收集了来自论坛的几个主题并提出了这个答案,希望它能让人们的生活更轻松.你不必理解代码只需复制和粘贴
下面是一个有点修改的版本.除了小的重构,我禁止粘贴到ReadOnly单元格中.
用法示例:
private void dataGridView1_KeyUp(object sender, KeyEventArgs e)
{
ClipboardUtils.OnDataGridViewPaste(sender, e);
}
