使用Gridview在刷新时遇到问题 [英] Using Gridview having problem in refreshing

问题描述

大家好，



我正在开发一个网络应用程序，我有一个gridview。 gridview不断刷新.Gridview有一列有文本框，还有一列有按钮。



现在我的问题是，我可以写入文本框，因为gridview在updatepanel.but as gridview不断更新，所以当我点击gridview按钮时会抛出一个错误，因为

 Sys.WebForms.PageRequestManagerServerErrorException：$时出现未知错误b $ b在服务器上处理请求。从服务器返回的状态代码是：12029 

请您需要。我正在等待答案以及任何其他人可以建议我的其他控件。



谢谢

解决方案

请查看以下几点

1）检查时间web.config中的值out

 <   authentication     mode   = 表单 >  
 <  表格    loginUrl   =  Users_Login.aspx   超时  =  555555555  /  >  
 <   / authentication  >  

2）你也可以点击确认如果用户存在身份验证，则为按钮。就像你仍然得到的被认证是真的



3）此外你可以写一些像下面的代码来检查错误的原因究竟是什么

 受保护的  Sub  ScriptManager1_AsyncPostBackError（ ByVal  sender 作为 对象， ByVal  e  As  Microsoft.Web.UI.AsyncPostBackErrorEventArgs）句柄 ScriptManager1.AsyncPostBackError 
  Dim  conn  As  新 SqlConnection 
 尝试 
 conn.ConnectionString = ConfigurationManager.ConnectionStrings（  ApplicationDatabase ）。ConnectionString 
  Dim  comm  As  SqlCommand = conn.CreateCommand 
 comm .CommandText =   AjaxRecordError 
 comm.CommandType = CommandType.StoredProcedure 
 comm .Parameters.AddWithValue（  exMessage，e.Exception.Message）
 comm.Parameters .AddWithValue（  exStack，e.Exception.StackTrace）
 comm.Parameters.AddWithValue （  exSource，e.Exception.Source）
 comm.Parameters.AddWithValue（< span class =code-string>  exServerName，Server.MachineName）
 comm.Parameters.AddWithValue（  date，DateTime.UtcNow）
 comm.Parameters.AddWithValue（  ip，Request.UserHostAddress）
 conn.Open（）
 comm.ExecuteNonQuery（）
  Catch  ex  As 异常
 最后 
 conn.Close（）
 结束 尝试 

如果您发现结果，请告诉我们任何其他可能的解决方案......

基于错误代码12029

来自MSDN： [ ^ ]

12029 ERROR_INTERNET_CANNOT_CONNECT

尝试连接服务器失败。

请检查您的设置（连接，防火墙等）

或者我认为你是超时。所以在web.config中增加脚本超时的值

不再ú。



错误12029.删除'或其他。

解决方案

Can you please check below points
1) check the time out value in web.config

<authentication mode="Forms">
            <forms loginUrl="Users_Login.aspx" timeout="555555555"/>
        </authentication>

2) can you also verify on clicking on the button if authentication exists for the user. Like are you still getting is authenticated as true

3) Further you can write some thing like below code to check what exactly is the reason for the error

Protected Sub ScriptManager1_AsyncPostBackError(ByVal sender As Object, ByVal e As Microsoft.Web.UI.AsyncPostBackErrorEventArgs) Handles ScriptManager1.AsyncPostBackError
      Dim conn As New SqlConnection
      Try
         conn.ConnectionString = ConfigurationManager.ConnectionStrings("ApplicationDatabase").ConnectionString
         Dim comm As SqlCommand = conn.CreateCommand
         comm.CommandText = "AjaxRecordError"
         comm.CommandType = CommandType.StoredProcedure
         comm.Parameters.AddWithValue("exMessage", e.Exception.Message)
         comm.Parameters.AddWithValue("exStack", e.Exception.StackTrace)
         comm.Parameters.AddWithValue("exSource", e.Exception.Source)
         comm.Parameters.AddWithValue("exServerName", Server.MachineName)
         comm.Parameters.AddWithValue("date", DateTime.UtcNow)
         comm.Parameters.AddWithValue("ip", Request.UserHostAddress)
         conn.Open()
         comm.ExecuteNonQuery()
      Catch ex As Exception
      Finally
         conn.Close()
      End Try

Please let us know the result or in case you find any other possible solution as well....

Based on the error code 12029

From MSDN:[^]

12029 ERROR_INTERNET_CANNOT_CONNECT
The attempt to connect to the server failed.

So check your settings (connection ,firewall, etc.,)
Or I think you are getting timeout. So increase the the value for script time out in web.config

Hi!

I don''t speak English. I''m brazilian.
I removed this: ´
My city: Criciúma.
I removed ´ and my city: Criciuma.
No more ú.

For error 12029. Remove ´ or other.
Ok?
