Excel VSTO中的复制粘贴正在删除更改事件而事件没有执行

Question

如果我将粘贴内容从A2单元复制到B2单元，则更改事件会很好，但是当我执行剪切和粘贴操作时，它不执行更改事件，因此我认为在剪切和粘贴过程中事件已被删除。以下是VSTO代码。

[我尝试过其他事件，例如取消选择或选择更改，但它们也不适用于从A2单元到B2单元的数据剪切和粘贴。

Blockquote我认为在剪切和粘贴期间事件已被删除。以下是VSTO代码。

您是否已通过设置断点并在复制粘贴后手动编辑单元格来确认这一点？

想到的一个选项是尝试捕获某个范围或整个工作表上的“粘贴”事件，但由于该事件似乎不存在，我发现以下线程可能会指导您找到解决方案Excel VBA How to detect if something was pasted in a Worksheet
