On page load I am populating my own list object, storing in session & it is getting stored, When I am debugging i can see that list object is stored in session, But When I am reading that session variable in next page, it's throwing error like
The type 'Dispensary.ResourceScheduling.Views.SchedulingPopup' exists in both 'WebApplication.dll' and 'App_Web_6bndsqgu.dll'
I have read in many places that referencing IRequiresSessionState or IReadOnlySessionState will allow me access to the Session scoped variables from within the ProcessRequest method in an ASHX file.
I have implemented these changes, as follows, and I am unable to retrieve this data still, as the server returns a null object reference error:
using System;
using System.Web;
using System.Web.SessionState;[code]....
The error is most certainly specific to pulling data from the session, yet I am 100% certain that the session contains data in this key.
It shouldnt matter where I am storing the data (cookies, vs db, etc), right?
Its related to datatable in gridview store in session and then session retrive and store to database. basically i am using gridview here creating new row for button click and these row adding untill user's last entry then submit all these entry to database. so i want to use session variable to store this data temporarily and after final entry user click on submit button and all data shold be save in db.

View 3 RepliesIn my WAP project I have a reference to another C# Project (non-web). In that C# project I have an app.config and I renamed it to [projectName].config
I then tried to grab a key from my [project].config from some code within my C# Project and it can't find it:
return ConfigurationManager.AppSettings["somekey"]
So I am wondering why it can't read my app.config. I would think that ConfigurationManager would be able to read keys form the Web project's web.config AND my [projectName].config (app.config) file that is in my referenced project as well?

After I formated my system, When I run my website on local IIS databases, aspnetdb.mdf don't seem to work. But works fine on local Cassini (VS).

Does it have anything to do with SQL Managment Studio? I din't take any backup of master database and all.
Have not run the ASP.NET Development Server for a while. Today I copied a production website to my workstation and ran it with VS 2008. The following error message popped up. What is the problem with the ASP.NET development Server on my workstation? The website on the Production server still ran okay.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 KEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesaspnet_stateParametersAllowRemoteConnection.
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 '127.0.0.1' as the server name.

View 2 RepliesI'm in the middle of moving a web application from IIS6 to IIS7. I've enabled "Windows Authentication" and added <deny users="?" /> to the authorization section of my web.config file. When the app was running on IIS6 my users where able to access the web app without logging in because their windows login was automatically recognized. This does not seem to be the case in II7. I can not get a value for "Current.User.Identity.Name" in my ASP.Net code.

I have a page that displays content retrieved from XML with no problems:
<?xml version="1.0" encoding="UTF-8"?>
<Root>
<Fields>
<NamePrompt>名字</NamePrompt>
</Fields>
</Root>
Page encoding is set to GB18030 and it displays perfectly. However, when I retrieve inputted text from HttpContext.Current.Request.Form that's been entered with double-byte characters, the retrieved string contains unreadable characters. Single-byte characters are fine, obviously.
I've tried the following to no avail:
byte[] valueBytes = Encoding.UTF8.GetBytes(HttpContext.Current.Request.Form["fullName"]);
string value = Encoding.UTF8.GetString(valueBytes);
I don't see this problem with other double-byte languages like Japanese or Korean. How can I successfully retrieve double-byte characters from a page that's GB18030 encoded?

User is allowed to choose any radio option and enter any value in the textbox beside it and then goes for submit button to move to next stage.

I load the controls in the panel based on the index of a combo control on the same form.it is done in selectedIndexChanged - This is working fine.
When i go for the submit button and ask for the textbox control, it says "object reference not set to instance of object", denoting that instance is not available. Moreover the panel control list gets empty automatically.

I am trying to update the database with the edited data. However, it did not manage to read the edited data from the textbox. It returned the retrieve data that I have done in the Page_Load instead. Is there any part of the code that I have written wrongly? I did manage not to use <EditItemTemplate> in my past project and manage to update the database with the same logic.

I need to be able to retrieve the correct UserID when some one inputs there username and password upon login and then some how retrieve it on a new page something like this to retireve it but unsure?
string usrName = Convert.ToString(Session["UserID"]);
I just dont know how to add the first part, the session into my login code so I can some how store the UserID in my session but also retrieve the correct UserID from the submitted data that takes from my mysql login table.
I have taken up a project at work that was left half finished by the last guy that used to work here, it involves choosing a country, region and town from some drop down lists this is all done in Javascript which leaves this as a problem for me so now I need to retrieve the value of the townID that is stored in a hidden value, I tried this by putting the townID value inside a session and then on postback (after clicking the button) I wanted to parse the session value to retrieve the correct article, but I receive the following error:
Value cannot be null.
Parameter name: String
Here is what I am doing with the code (on the button):
[Code]....
(Postback)
[Code]....
This is the code I am using, the TownID is coming out null!
I want to pass multiple values to another page from my gridview. For sending i got this codes : (writing same page selected values)

Here is my question How can i catch from another page this values?
