在此先感谢

<！- 动态调试编译
将编译设置为debug ="true"以启用ASPX调试.否则，将此值设置为
false将提高此应用程序的运行时性能.
设置编译debug ="true"以插入调试符号(.pdb信息)
进入已编译的页面.因为这会创建一个较大的文件，该文件将执行
更慢的是，只有在调试时才应将此值设置为true，
在其他所有时间均为假.有关更多信息，请参阅有关以下内容的文档:
调试ASP.NET文件.

<！- 自定义错误消息
设置customErrors mode ="On"或"RemoteOnly"以启用自定义错误消息，将"Off"禁用.
添加< error>您要处理的每个错误的标签.

<！- 应用级跟踪日志记录
应用程序级跟踪可为应用程序中的每个页面启用跟踪日志输出.
设置trace enabled ="true"以启用应用程序跟踪日志记录.如果pageOutput ="true"，则
跟踪信息将显示在每页底部.否则，您可以查看
通过从Web应用程序浏览"trace.axd"页面来获取应用程序跟踪日志
根.
->
< 跟踪 =" requestLimit > 10" pageOutput =" false" traceMode SortByTime" localOnly =" / >
<！- 会话状态设置
默认情况下，ASP.NET使用cookie来识别哪些请求属于特定会话.
如果cookie不可用，可以通过将会话标识符添加到URL来跟踪会话.
要禁用cookie，请设置sessionState cookieless ="true".
->
< sessionState =" InProc" stateConnectionString tcpip = 127.0 .0.1:42424" sqlConnectionString 数据源= 127.0.0.1; Trusted_Connection =是" 无cookie false" 超时 =" / <！- 全球化

< system.codedom >
< /system.codedom >

解决方案
由于超时导致服务器会话丢失.您可以使用web.config中的以下语句来增加时间，-
< pre lang ="xml">& lt; system.web& gt;
& lt; sessionState timeout =& 540& quot;/& gt;</pre>
您需要在WEB.Config中增加Session timout
Dear sir/Mam
I am Shailendra Singh and I am new to .Net . I am getting an error in Project. The error is session loss on server in asp.net(C#) .Please Any help for particular problem .
Thanks In Advance
MY web.config file .

<!-- DYNAMIC DEBUG COMPILATION
Set compilation debug="true" to enable ASPX debugging. Otherwise, setting this value to
false will improve runtime performance of this application.
Set compilation debug="true" to insert debugging symbols (.pdb information)
into the compiled page. Because this creates a larger file that executes
more slowly, you should set this value to true only when debugging and to
false at all other times. For more information, refer to the documentation about
debugging ASP.NET files.
-->
<compilation defaultLanguage="c#" debug="true">
<assemblies>
<add assembly="System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
</assemblies></compilation>
<!-- CUSTOM ERROR MESSAGES
Set customErrors mode="On" or "RemoteOnly" to enable custom error messages, "Off" to disable.
Add <error> tags for each of the errors you want to handle.
"On" Always display custom (friendly) messages.
"Off" Always display detailed ASP.NET error information.
"RemoteOnly" Display custom (friendly) messages only to users not running
on the local Web server. This setting is recommended for security purposes, so
that you do not display application detail information to remote clients.
-->
<customErrors mode="Off"/>
<!-- AUTHENTICATION
This section sets the authentication policies of the application. Possible modes are "Windows",
"Forms", "Passport" and "None"
"None" No authentication is performed.
"Windows" IIS performs authentication (Basic, Digest, or Integrated Windows) according to
its settings for the application. Anonymous access must be disabled in IIS.
"Forms" You provide a custom form (Web page) for users to enter their credentials, and then
you authenticate them in your application. A user credential token is stored in a cookie.
"Passport" Authentication is performed via a centralized authentication service provided
by Microsoft that offers a single logon and core profile services for member sites.
-->
<!--<authentication mode="Windows"/>-->
<!-- AUTHORIZATION
This section sets the authorization policies of the application. You can allow or deny access
to application resources by user or role. Wildcards: "*" mean everyone, "?" means anonymous
(unauthenticated) users.
-->
<authorization>
<allow users="*"/>
<!-- Allow all users -->
<!-- <allow users="[comma separated list of users]"
roles="[comma separated list of roles]"/>
<deny users="[comma separated list of users]"
roles="[comma separated list of roles]"/>
-->
</authorization>
<!-- APPLICATION-LEVEL TRACE LOGGING
Application-level tracing enables trace log output for every page within an application.
Set trace enabled="true" to enable application trace logging. If pageOutput="true", the
trace information will be displayed at the bottom of each page. Otherwise, you can view the
application trace log by browsing the "trace.axd" page from your web application
root.
-->
<trace enabled="false" requestLimit="10" pageOutput="false" traceMode="SortByTime" localOnly="true"/>
<!-- SESSION STATE SETTINGS
By default ASP.NET uses cookies to identify which requests belong to a particular session.
If cookies are not available, a session can be tracked by adding a session identifier to the URL.
To disable cookies, set sessionState cookieless="true".
-->
<sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes" cookieless="false" timeout="60"/>
<!-- GLOBALIZATION
This section sets the globalization settings of the application.
-->
<globalization requestEncoding="utf-8" responseEncoding="utf-8"/>
</system.web>
<system.codedom>
</system.codedom>
<system.webServer>
</system.webServer>
</configuration> 解决方案
Session loss in server because of time out. You can increase time with the following statement in web.config,-
<pre lang="xml"><system.web>
<sessionState timeout="540"/></pre>
You need to increase the Session timout in WEB.Config
