Maintaining session state in a visual webpart

Posted By:      Posted Date: September 27, 2010    Points: 0   Category :SharePoint

I am building a visual web part that will allow users to navigate the document libraries and view the *.pdf files within them. I am using a static class which exposes a number of properties which essentialy get and set session objects. For example here is the CurrentDocumentLibrary;

Session State throws error in ASP.NET Site Pages for SharePoint 2010 portal using Visual Studio 2010


I'm developing Visual Studio 2010 solution for site pages. I’ve created Site Pages in SharePoint 2010 and I’m trying to access Session variables in code behind in ASP.NET but it throws the following error.

Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration>\<system.web>\<httpModules> section in the application configuration.

I set the page directive as enableSessionState=&quo

SQL Server Session state problem.


Hi to all,

I have some things that I want to know. I am right now using a free asp.net webhosting ("somee.com"). The problem is that when I am visiting a page, there's a tendency that values stored in my session variables are lost. Therefore, it causes an error when the requested page is loaded.

1. I am thinking of using sessionState mode="SqlServer". Will it solve my problem?

Actualy Im working on it but Im having problems when connecting to the sql database.

2.  Is that a problem in the webhost?

3. Do free webhosting sites provide allow session state in the sql server?. Because ive tried it locally into my computer and error say's i should intall the ASP.NET Session State SQL Server version 2.0 or above.

Custom Server Control Property not maintaining state


I have created a server control consisting of a TextArea and a div under it.  My goal is to create my own asp:TextArea type control.  the div is for a Character count of the text area and seems to work ok but i added a CharacterCountVisible property to the control that is always returning true.  See Proptery definition below


<Bindable(False), Category("Appearance"), DefaultValue("True"), Localizable(True)> Property CharacterCountVisible() As Boolean
        Return _CountBoxVisible
    End Get
    Set(ByVal value As Boolean)
        _CountBoxVisible = value
    End Set
End Property

Note the _CountBoxVisible variable is define inside the class as :

Dim _CountBoxVisible as Boolean = True

What I am trying to do is give the user/coder the option to show/utilize the char count feature.  Can make it disappear with textarea1.CharacterCountVisible = False but setting it to true will not make it display.

Taming the Stateless Beast: Managing Session State Across Servers on a Web Farm


Running a Web farm means managing session state across servers. Since session state can't be shared across a Web farm with Internet Information Services 5.0, a custom solution is required. One such solution using a tool called the session manager is described here. The article begins with a description of the SQL Server database used to store state information, the stored procedures used to update it, and the retrieval of session data. ASP code drives the session manager tool and the COM and COM+ components that run the stored procedures.

Session State Problem




I just for the first time into a session state problem. So I am hoping someone

here has the answer.


I have written an ASP.Net website and tried to implement the common poor mans online user count.
The problem I am having is the following.

On App_Start I create a variable and assign it the value of 0;

Then increase the number on session_start and decrement on session_end.

On my local IIS it works perfectly from IE8 and Opera. The value increments correctly.
As soon as I upload to my live server. The value increments on every link I click and every page refresh when I test with IE8.
This does not happen when testing with Opera.

Could someone please shed some light on the subject.

Good news for those of you who get "Unable to make the session state request to the session state se


Dear all,

Due to the known problem of session variables getting lost if using InProc-server during frequent changes in development, I had to choose between SQL and ASP.NET State server, so I opted for the second. Initially, all fine, but after using it for a few days, I started to get this error:

 Server Error in '/cv2' Application.
Unable to make the session state request to the session state server. Please ensure that the ASP.NET State service is started and that the client and server ports are the same.  If the server is on a remote machine, please ensure that it accepts remote requests by checking the value of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aspnet_state\Parameters\AllowRemoteConnection.  If the server is on the local machine, and if the before mentioned registry value does not exist or is set to 0, then the state server connection string must use either 'localhost' or '' as the server name.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Session State for Listview Items?

Hi, I have a listview control, in it each item will have a checklist eg - Pass / Fail which will then have a label displaying the selected value. I also have datapager wired up to the listview. When i toggle between the datapages and toggle back, any result previously submitted will be wiped. I am thinking i should be using session state to temporarily store then info, and then once the session is finished use a submit button to send all values and ids into an xml. 1. Is this the right way of approaching the situation? 2. How would i specify session state for listview items, eg would i angle it through a itemdatabound event or the application itself?   Any assistance and advice would be appreciated as i have only started looking at state management and xml storage.  

Accessing Session State in a User Control

We have a web site that implements a custom SiteMapProvider using a User Control added in the master page. I need to be able to limit the sitemap nodes added depending on the logged in user, that is, certain users should not see certain sitemap nodes. Currently, the login processing code determines if users are in the certain category or role and then sets a value in session state, for example, Session["UserInRoleXXX"] = "Yes"; I tried changing the code in the user control to check the session state, but I got the following error: NullReferenceException ... Object reference not set to an instance of an object." Can session state be accessed in a user control? If so, how? If not, any suggested solutions? Thanks in advance for any help.

Problem setting Foreground with Visual State Manager (WPF - .Net v4.0

0 down vote favorite I have a WPF application, and I am attempting to style a TextBox using the .Net v4 Visual State Manager. Specifically, I am attempting to set the colors of the Foreground and Background for the MouseOver state. What is happening is that, while the background and border are changing perfectly, the foreground is not. If the brushes that I am using get their color via a StaticResource, then the foreground does not change at all. If the brushes that I am using get their color via a DynamicResource, then when I mouse over a TextBox, the foreground of all TextBoxes change. Clearly, either I'm doing something wrong, or what I want to do is simply not possible with VSM (which would be rather disappointing). Here are the resources that I am using:   <Color x:Key="ControlBackgroundColor" R="178" G="178" B="178" A="255" />  <Color x:Key="ControlForegroundColor" R="0" G="0" B="0" A="255" />  <Color x:Key="BorderColor" R="127" G="127" B="127" A="255" />  <Color x:Key="MouseOverControlBackgroundColor" R="0" G="0" B="0" A="255" />  <Color x:Key="MouseOverControlForegroundColor" R="255" G="2

Session state and MVC

I'm trying to maintain session state for a user with MVC.  What is the best approach?


I created a page which runs a THREAD.  Unfortunately, at the end of the THREAD which is designed to populate a table, an error is produced.  It says that the SESSION STATE CAN ONLY BE USED WHEN ENABLESESSIONSTATE IS SET TO TRUE.  I added the ENABLESESSIONSTATE to my page directive.  However, it seems that this does not suffice.  It also says the I need to add a CUSTOM SESSION STATE module in the CONFIGURATION section.  Is there an example of where I do this in the WEB.CONFIG.  I need a fairly detailed WEB.CONFIG as I don't want to break what I have at the moment. TIAJohn

What are the benefits of using ASP.NET Session State in a Web Service

I have a question regarding session state usage in a  Web Service method. I thought about this situation as I came across an article http://msdn.microsoft.com/en-us/library/aa480509.aspx Situation is that A. There are web service methods which are being exposed. One web method to store value in a session state and another to get value from session state. B. There is another asp.net website which calls the above web methods.        B                    ----------------------------------->       A (Another ASP.NET Website)                 (WebService hosted in an ASP.NET website)   Questions: Does webmethod can store data in a session variable in Webservice application's IIS (in Proc)? I tried this (refer below code snippets) but I was not able to store and get data thru webmethods into/from state. Why?? What is the use of storing it in the state of the Webservice's website IIS (in proc). Will there be any session objects create due to any web service calls from clients? What are the benefits of saving a value in WebService's session, not in the calling website's session. A WebService's webmethod can able to use session state, does that mean that a session will b
