推荐答案
它是一个自定义网格，因此它是从GridView继承的.它只是引发基类事件OnPageIndexChanging，该事件的声明在GridView中.使用IDE浏览事件的定义(在OnPageIndexChanging上单击鼠标右键->转到定义")，您将看到它的位置.
It''s a custom grid, so it''s inheriting from GridView. It''s simply raising the base class event OnPageIndexChanging, the declaration for that is in GridView. Use the IDE to browse the definition of the event (right mouse over OnPageIndexChanging -> go to defintion) and you will see where it is.
基本上，任何事件默认情况下都是空的.我们需要在事件中定义代码才能执行.
让我们检查一下您的分页.
您是否在页面上定义了OnPageIndexChanging事件.
如果是，则在PageIndexChanging中编写以下代码.
Basically any event is empty by default. we need to define the code in that events to carried it out.
Lets check about your Paging.
Have you defineOnPageIndexChangingevent on Page.
If yes then write following code in PageIndexChanging.
GridView1.PageIndex = e.NewPageIndex;
//Bind grid Again.
要在GridView中使用分页，您需要注意以下事项
1.指定PageSize.
2.编写PageIndexChanging事件.
To use paging in GridView you need to take care of following things
1. Give PageSize.
2. write PageIndexChanging event.
