Question

Hi All,

There is a report section in my MVC application. When I try to get report by putting break-pint it all goes  alright but when It redirects to another tab it shows error

Session state has been disabled for ASP.NET.  The Report Viewer control requires that session state be enabled in local mode.

I looked for the solution and found some code to fix it. But still the same result. The solution I found on google is to modify webconfig with some following tags.

<pages enableSessionState="true"  validateRequest="false" />

<httpModules>
      <add name="Session" type="System.Web.SessionState.SessionStateModule" />
    </httpModules>
 <sessionState mode="InProc" cookieless="false" timeout="20"/>
<system.webServer>
    
    <modules runAllManagedModulesForAllRequests="true">
      <remove name="Session" />
      <add name="Session" type="System.Web.SessionState.SessionStateModule"
      preCondition="" />
    </modules>
  </system.webServer>

Please suggest.

Hi demoninside,

Session state has been disabled for ASP.NET.  The Report Viewer control requires that session state be enabled in local mode.

To solve this problem, I recommend you can open the Sharepoint PowerShell as administrator and run the following command  'Enable-SPSessionStateService -Defaultprovision'.

For more details, you could refer to this link : 

SharePoint 2013: Session state has been disabled for ASP.NET. The Report Viewer control requires that session state be enabled in local mode.

If this still cannot solve your issue , you can also refer to this link :

Hi demoninside,

SharePoint Management Shell is an enhanced version of Windows PowerShell with the SharePoint libraries preloaded. You can run SharePoint commands from Windows PowerShell, you just have to load the SharePoint libraries manually.

Don't need those for this issue. I just made a silly mistake. In my form directive I put the EnableSessionState="False". Now I have change sit to True

<%@ Page Language="C#" AutoEventWireup="True" CodeBehind="ReportViewerWebForm.aspx.cs" EnableSessionState="True"  Inherits="ReportViewerForMvc.ReportViewerWebForm" %>

It is working fine now.
