推荐答案

关于删除事件

GridView1.DeleteRow（ GridView1.SelectedIndex）;

On Delete Event
GridView1.DeleteRow(GridView1.SelectedIndex);

首先获取某些集合中的所有数据，比如说，在列表中< t>< / t> 。



将此列表作为数据源分配给Gridview。



并执行类似 INSERT-UPDATE-DELETE此列表< t> 的操作，然后再将其绑定到Gridview。



我没有任何实际的例子，所以我无法通过它来解释。但是，我刚刚做了这个，并且工作得很好。



请记住，你所要做的就是在List< t>周围玩游戏。而不是数据库:)

First get all the data in some collection, let's say, in a List<t></t>.

Assign this List as a DataSource to the Gridview.

And perform the operations like, INSERT-UPDATE-DELETE on this List<t> and then again bind it to the Gridview.

I don't have any working example, so I can't explain it through it. But yeah, I have done this a while ago, and worked properly.

Remember, all you have to do is, play around the List<t> rather than Database :)
