推荐答案
据我所知..你正在用Java Script编写事件，它有一个Java脚本的逻辑在页面加载时触发...因此，它不会在网格视图的行编辑中被触发。
在.cs页面上定义事件而不是它当你编辑这行时，gona会被解雇。
希望它会有所帮助...或至少会给你一个暗示做一些更好的事情。

As far as I know.. You are writing the events in Java Script and There is a logic of Java script that it got fired when page loads... So that''s y its not getting fired on row editing of the grid view.
Define the events on .cs page and than it gona be fired when you will edit the row.
Hope It will help... or will at least give you a hint to do some thing better.
