            this.nullShow.Visible = false;
           int a= this.dgvProductList.EditIndex;//  测试这段代码的编辑行为0
           this.dgvProductList.EditIndex = -1;//然后赋值为-1  取消编辑行
           int b = this.dgvProductList.EditIndex;//断点显示值为-1｝上面的测试之后 this.dgvProductList.EditIndex 显示为-1. 但是仍旧取消不了编辑行？？ 为什么？？？  帮忙看一下吧。谢谢！

Answer 1

GridView 的 DataSource 楼主你是通过代码设置的，则：    设置 GridView 的 EditIndex 为 -1 后，
    需要重新设置 DataSource 属性，并且调用 DataBind() 方法。

Answer 2

What do you mean? I don't understand.
You said has nothing to do with my issues!

Answer 3

每次设定完EditIndex之后要重新绑一下数据，才能体现出来
