问题描述
按这图上的步骤点就会崩溃。不知道怎么调试了。
解决方案
解决方案二：
贴代码吧，应该知道在哪行报错的吧
解决方案三：
在错误代码处打断点，记住是哪步操作出错，然后看当时的各个对象的值，是否超出索引等，然后一步步往上追踪
解决方案四：
附件怎么放上来
解决方案五：

解决方案六：
dataGridView_f.Rows[0].Cells[3].Value="sdfsf";这句出掉
解决方案七：
我就是想在点的那行的Cell【3】的值改成一个特定值，新增行除外
解决方案八：
引用5楼wyd1520的回复:
dataGridView_f.Rows[0].Cells[3].Value="sdfsf";这句出掉
不去掉不行吗
解决方案九：
你是想点某一行后把那一行的CELL值改掉？if(dataGridView_f.Rows.Count>0){dataGridView_f.Rows[0].Cells[3].Value="sdfsf";这句出掉}
