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
前台功能：1. 首页－查询配置，显示最新发布新闻，2. 自选配置－根据你所选的CPU或主板型号自动配置成主机并自动计算总价和产生机器ID方便以后查询。3. 今日报价－根据你在后台发布的配件报价信息在这里清楚发显示出来，并有价波动功能。4. 留言功能－这个不用说了，除了和大多留板一样，就是多了一些产品订购信息。后台功能：1. 超级管理员功能，可以增加高级管理员和数据输入员，各有不同功能限制,密码再以
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。
