C# 在gridview中分页时尝试了解错误源
好的！所以，从过去的一周开始，我一直在试图找出为什么我会犯这个错误，但没有成功 <>我在我的网站中间有这个网格视图设置，我只是试图从数据库中画出大量的行（比如结果表中的20行）。当我设置allowpage=“true”并设置PageSize=“10”时，我得到 HTTP错误404.15-未找到请求过滤模块配置为拒绝查询字符串过长的请求。加载网站时单击网格视图的第2或3页时出错 但是当我删除allowpage=“True”和PageSize=“10”时，我会得到大量条目 代码C# 在gridview中分页时尝试了解错误源,c#,asp.net,gridview,C#,Asp.net,Gridview,好的！所以，从过去的一周开始，我一直在试图找出为什么我会犯这个错误，但没有成功 我在我的网站中间有这个网格视图设置，我只是试图从数据库中画出大量的行（比如结果表中的20行）。当我设置allowpage=“true”并设置PageSize=“10”时，我得到 HTTP错误404.15-未找到请求过滤模块配置为拒绝查询字符串过长的请求。加载网站时单击网格视图的第2或3页时出错 但是当我删除allowpage=“True”和PageSize=“10”时，我会得到大量条目 代码 <%@ Page

因此出现了错误。根据您的喜好增加webconfig中设置的值。我按照您所说的那样尝试（配置了我的web配置文件），但仍然收到了相同的错误。接下来，我甚至将我的类名称从“StaffDetailsForStaffSalaryMonitoringSystemAdd”减少到“StaffDetailsSmsadd”但它仍然给了我同样的错误。此外，我甚至将maxQueryStringLength和maxUrlLength的值设置为“2097151”这是他们可以接受的最大值，但我仍然得到了相同的错误。我可以做些什么来实现这一点？我已经更新了我的答案。尝试在您的web配置中使用这两种设置的组合。哇！！！成功了。谢谢：）如果可能的话，你能解释一下你是如何找到解决方案的，因为这不是很直观。通过这个链接。你能粘贴你在回帖上得到的链接吗？我还是觉得出于某种原因，生成的查询字符串太长了。
