亲爱的朋友，



在gridview rowupdating事件中，该行实际上未更新。它会在更新前处理该行的事件。

Dear Friend,

In gridview rowupdating event, the row is not actually updated. It handles the event for the row before updates.

Please go through the link below; you will get to know the problem in your code.

我认为当您点击更新链接时，Gridview会在获取新值之前再次绑定。



你必须忘记在 GridView.DataBind（）之前忘记使用 if（！IsPostBack）。



理想情况下，在绑定之前，您应该检查下面的内容......

I think when you click update link, Gridview is binding again before taking new value.

You must have forgotten to use if(!IsPostBack) before GridView.DataBind().

Ideally before binding you should check that like below...

if(!IsPostBack)
{
    // Code to bind the GridView.
}
