Hii允许在griedview中进行分页功能.可能是ds中的记录数大于gried中的默认记录.增加griedview的页面大小或将其嵌入具有分页功能希望它对您有帮助... !!

Hii allow paging functionallity in your griedview.May be the number of records in the ds is more than the default records in gried.either increase the pagesize of griedview or embed it with paging functionallity.Hope it helps you...!!

这个问题只有一种解决方法..

您的问题是您尚未处理gridview的PageIndexChanging事件..只需为您的gridview编写一个事件处理程序即可.它将100％工作..

编写活动的步骤:

1)选择您的网格视图.
2)转到该网格视图的属性窗口
3)选择PageIndexChanging事件，然后双击该事件

编写代码以处理gridview分页(如果需要)..
如果您需要页面视图的分页编码，请与我联系.
尝试一下.如果您愿意，请接受答案..
最好的..:)

There is only one solution to this problem..

Your problem is that you have not handled PageIndexChanging event of your gridview.. Just write an event handler for your gridview.. It will 100% work..

steps for writing the event:

1) select your grid view.
2) go to properties window of that grid view
3) select the PageIndexChanging event and double click on the event

write the code to handle the gridview paging(if required) ..
If you need the paging coding for grid view just contact me..

try it.. Accept the answer if you like it..
All the best.. :)
