问题描述
在Asp.net
In Asp.net
<asp:GridView ID="grvMatGrp" runat="server" AutoGenerateColumns="false" Width="50%" AllowPaging="true" PageIndex="10" OnPageIndexChanging="grvMatGrp_PageIndexChanging"
OnRowDeleting="grvMatGrp_RowDeleting">
在C＃
In C#

{
Matflag = 1;
grvMatGrp.PageIndex = e.NewPageIndex;
GetMaterialList();
}
public void GetMaterialList()

And here in page load

{
try

}
}
catch (Exception ex)
{

推荐答案
几点：
PageSize - 你在哪里定义这个？我在你发布的代码中看不到它。
PageIndex - 你已经将它定义为GridView标记中的一个属性：
Hi,
A couple of points:
PageSize - where do you define this? I can't see it in your posted code.
PageIndex - you have defined this as an attribute in the GridView markup:
<asp:GridView id="grvMatGrp" ... PageIndex="10" ... ></asp:GridView>
我会从标记中删除它，并将其留给您的代码在PageIndexChanging（）中为你照顾它。
我还建议读一下这篇文章：
< a href =http://www.codeproject.com/Articles/816953/How-To-Implement-Paging-in-GridView-Control-in-ASP>如何在ASP.NET中的GridView控件中实现分页 [ ^ ]
...因为这提供了比我在此解决方案中更好的分页功能解释。
...希望它有所帮助。
I would remove this from the mark up, and leave it to the code you have in PageIndexChanging() to take care of it for you.
I would also recommend that have a read at this article:
How To Implement Paging in GridView Control in ASP.NET[^]
... as this provides a better explanation of the available paging functionality than I can in this solution.
... hope it helps.
网格在每个pageindex上绑定相同。所以尝试根据pageindex获取新数据绑定网格
谢谢
Hi,
you grid is binding same on every pageindex. so try to get new data to bind the grid based on pageindex
Thanks
