大哥们我的Winform的DataGridview的数据源是数据库连接得到的，你帮小的看看这个怎么定义动态生成的DataGridview进行“数据修改操作”的事件呗。不胜感激啊！
简单的说下自己的具体编码实现功能吧：
1.根据用户输入的一个方程，解析出来其自变量如：x1,x2
2.在DataGridView1中定义每个变量的分布类型，

x1 正态分布

x2 对数正态分布

定义完毕后便是下面的代码，上面的功能小的已经实现了；
3.下面的代码是对各个变量在服从相应分布类型时所需要的参数信息，比如正态分布需要均值和方差；之所以选择动态生成自变量数个datagridview是因为各分布类型的参数个数和名称并不完全相同。
4.每个分布类型（如正态分布，对数正态分布）都在数据库中初建一个数据表。
