我昨天发布了这样的内容，但想想也许我的措辞不是很好，因为我通常会在几分钟内得到多个答案而且什么都没有。
我使用VS 2008在C＃环境中工作。我使用datagridviews，并且可以使用按钮（DataGridViewButtonColumn）或复选框（DataGridViewCheckBoxColumn）来处理它们而没有任何问题。我已经使用按钮通过“CellContentClick”功能触发简单操作。我已经使用复选框检查所选项目，然后使用外部数据网格视图按钮，但仍然在表单中运行批量处理。我的代码就在这篇文章的最底部。
我现在面临着创建具有两者的datagridview的任务;所以我将有一列按钮（DataGridViewButtonColumn），一列复选框（DataGridViewCheckBoxColumn），然后是一个按钮otuside引用复选框列的DGV。
我留下的是我无法弄清楚如何解决CellContentClick，即使在我单击复选框时也会触发，因为当我单击复选框时我不需要触发任何内容。我已经让底层代码跳过CellContentClick中的代码，因为它识别出它不是单击按钮的正确列，但是复选框永远不会被选中，因为CellContentClick在识别框已被检查之前触发。
任何人都有任何代码段，链接或建议。我不太熟悉DGV的基础知识，但意识到我真的需要学习。
