I am developing an application using VS2008 .Net 3.5 with MS SQL 2008 targeting .Net 2.0
The project is created as Web Application ... does not use any third party controls
I have changed both my web.config and assemblyinfo.cs with AllowPartiallyTrustedCallers ...
I am still getting the error message, "That assembly does not allow partially trusted callers"

first of all: this probelm was already an issue in [URL] but it does not resolve my problem: I have VS2008 and SQL Server 2008 Express with Adv. Option istalled. When compiling a page with the reportviewer control I get the error Type 'Microsoft.Reporting.RdlBuildProvider' cannot be instantiated under a partially trusted security policy (AllowPartiallyTrustedCallersAttribute is not present on the target assembly). C:websitesadAgencyweb.config
From the obove mentioned post I learned to use <trust level="Full" /> in the web.config file (which I never used on other Implementations that work). Now the compilation works, but when I start the web application and call that page I get a lot of JScrip Errors like: Runtime error in Microsoft JScript: 'RSClientController' is undefined, which comes from a line in the dynamic page.aspx file: document.getElementById('ctl00_maincontent_ReportViewer1').ClientController = new RSClientController "ctl00_maincontent_ReportViewer1_ctl03", "ReportFramectl00_maincontent_ReportViewer1", ...
I should mention, that I had SQL Server 2005 Express uninstalled before the 2008 version.

I tried to export a grid view to pdf using iTextSharp. When i build the program it does not leave me any exception.But when i tried to run the program and click on "Export to PDF" button, it leaves me with an following exception saying
"Could not load file or assembly 'itextsharp, Version=4.1.2.0, Culture=neutral, PublicKeyToken=8354ae6d2174ddca' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)"
I can guess that it is not a dll error.

I have recently discovered that I am affected by this bug http://www.mail-archive.com/mono-bugs@lists.ximian.com/msg71515.html
Well,at http://www.mail-archive.com/mono-bugs@lists.ximian.com/msg71529.html they say the work around is to create a global policy assembly and redirect the assemblies that way since it is not read from the web.config.
How do you actually do what they describe there? There is a huge documentation gap in that area with Mono.Also,I can't just recompile the assembly to use the new Mono assembly versions because the assembly is closed source.(but it does work with Mono.)

I'm using WCF services ensuring that UserName/Password must be provided for each request. I need use same service from many clients, but I need impersonate the call to access the appropriate resources for each client. When I call the service directly from the client there is no problem, because I use for each client a pair UserName/Password defined in theirs web.config. The problem came when I need to call a second Web service from a call to the first-one using the same identity. This second Web service requires UserName/Password, but I only know who is the caller (UserName) but not the password.
How I can impersonate this second call without knowing the password for the corresponding username?
EDIT: The app (Web App and Services) is running in a shared hosting environment where I can't use Windows Authentication to configure Kerberos for Delegation. I have defined a UserNameValidator to process on each call the pair UserName/Password against a custom SQLServer database. Moreover, the intended customers of this app will use it from Internet, without requiring a windows account, that is because I need a more flexible, SQL-based, authentication schema.

the page can be seen here [URL]
the client side validation is working for the adding date and time, but there is no validation firing for the count and room fields, I think i have coded them all the same, see sample for time and room below, maybe somebody see's something i missed? the validation group fires when the add button is clicked. also if possible I would like to get validation messages to appear in a validationsummary control that I already have coded and that is working when using the edit/update the rows presented with existing data.

I have an ASP.NET 2.0 web app which calls a one way web method on a web service. This web method contacts remote servers and pulls back config information to confirm the state of new server builds (settings etc) and inserts the collected data into a SQL database. The web app is supposed to pass through the callers kerberos ticket to the web service and then again to the newly built server which is being checked, all via impersonation and delegation using the calling users administrator privileges.
The trouble is, I just can't get the web service to run under the callers context. I have the SPN's set up, delegation turned on in the active directory objects for the computer running the web app and service and the worker process domain user service account. I have windows authentication on and impersonation set to true in both the web app and service's web.config, integrated authentication in IIS, and IE settings are all ok. All has been checked out and passes the tests in DelegConfig, but it still won't work.
It appears that any data that's is written to the database is written under the context of the web pool service account, and not the calling users, plus along with the fact that I get access denied messages when trying to collect data from the server says impersonation isn't working. Also, is it possible to run the checks under the calling users context, but write to the database with the web pool identity service account without specifying the user details in the web config?? I am working in a secure environment and we must user windows based accounts only, no SQL accounts.

I'm trying to write my first server control. It's supposed to be a pager (like in the GridView Control Pageing-"thingy").
(It looks something like this : 1 2 3 4 5 6 7 8 9 10 ...)
I'm trying to implement it by making the control inherit Table properties and then adding two rows. One row has a hidden field that has the current selected page and the other has LinkButtons in individual TableCells.
The problem I'm facing is that the LinkButton.Click event only fires on the first 10 linkButtons but not the dots (...). What I mean is, when I press the dots (...) it renders like this: .... 11 12 13 14 15 16 17 18 19 20 ... BUT when I press any of these LinkButtons the control just "reloads" itself and renders from 1 to 10 ... (and the Event never fires) I don't know what I'm doing wrong but I think it has something to do with the "override" functions because I don't know which to use. I have tried quite a few but haven't found the right way to do this. The Code I got so far:

My web service app on my Windows XP box is trying to log in to my sql server 2005 database on the same box. The machine is part of a domain. I am logged in in the domain and I am an admin on my machine. I am using Windows Authentication in my connection string as in "Server=myServerAddress;Database=myDataBase;Trusted_Connection=True". SQLServer is configured for both types of authentication (mixed mode) and accepts remote connections and accepts tcp and named pipes protocols. Integrated authentication is enabled in IIS and with and without anonymous access. 'Everyone' has access to computer from network setting in local security settings. ASPNET is a user in the sql server and has access to the daatabase. user is mapped to the login.
The app works fine for other developers which means the app shouldn't be changed (It's not new code). So it seems it's my machine which has an issue.
I am getting the error "Login failed for user ''. The user is not associated with a trusted SQL Server connection" Note the blank user name. Why am I getting this error when both the app and database are on my machine? I can use SQL Server authentication but don't want to. I can connect to the database using SSMS and my Windows credentials.
It might be related to setspn, kerberos, delegation, AD. I am not sure what further checks to make?

Before using any class in your website project/page we have to add it's assembly reference to our project. Right?
Now, when I am using SmtpClient class from System.Net assembly after adding the System.Net.Mail namespace in namespace node of application's web.config file but without adding assembly reference to the project, it still accepting and running the code. Why?
I enquired the machine's web.config file located at C:WINDOWSMicrosoft.NETFrameworkv2.0.50727CONFIG but didnt find assembly reference for System.Net there also.
So bit confused how it is working and where the assembly reference has been added and how?

i have a beginners question. I would like to build a website with n areas with usercontrols inside for different actions. For example one usercontrol should show up last n logged in users, or another usercontrol should do a long running operation and should show some calculated information on sales information etc.
Building these controls and the page for this is no problem without AJAX, but how could i make it, that the n single usercontrols load AFTER the base page is loaded with an progress bar like "Loading data. Please wait." and when its finished it should show the information.
How could i make that? I think that this is possible, cause i saw it on several websites.
My first testing was to put two or more updatepanels and in each update one usercontrols. But that didnt work.

I have a asp.net treeview control that I need to be able to set a parent node to partially checked to show that child nodes are checked. Basically I need a 3 state or multi-state checkbox. All I can see from looking through the code is ways to set checked true or false.

I've created a service that validates credentials against Active Directory using System.DirectoryServices.AccountManagement. I need to validate credentials against the local domain as well as a trusted domain. The response time for validating credentials is fast for both the local and trusted domain when run on my computer. When I move this service to our server, the local domain response is fast however, the trusted domain response is very slow (20 - 30 seconds).
I've also found that if I change the domain name in the PrincipalContext from the NetBios name to the DNS name it corrects the the performance problem on the server.
Here's some examples
PrincipalContext context = new PrincipalContext(ContextType.Domain, sNetBiosName)
context.ValidateCredentials(sUsername, sPassword)
On the server, the above will take 20-30 seconds using the NetBios Name
PrincipalContext context = new PrincipalContext(ContextType.Domain, sDNSName)
context.ValidateCredentials(sUsername, sPassword)
Using the DNS name the response is 0-2 seconds
Any ideas on what needs to be setup on the server to speed this up using the NetBios name?
