  • retain drop down value page posting back to itself asp.net

    - by d3020
    I have an aspx page that has... if (!IsPostBack) { PopulateBrand(); in the Page_Load. This PopulateBrand() simply populates my drop down. That works great and on post back it retains the value. The problem I'm having is that there is also a link on the page that is posting back some parameters to this page. What is happening is that when this is clicked it's falling through this !IsPostBack section and wiping out my drop down values that I had selected and repopulating it. How can I prevent this and just retain what I selected when this page is posting back to itself when the link is clicked? Thanks.

  • WS-Security using the ASMX file in ASP.NET 3.5

    - by Adam
    Basically I need to setup my ASMX file so that when I pull it up in a browser to display the WebMethod specification the Soap Header conforms to this format: <soap:Header> <wsse:Security> <wsse:UsernameToken wsu:Id='SecurityToken-securityToken'> <wsse:Username>Username</wsse:Username> <wsse:Password>Password</wsse:Password> <wsu:Created>Timestamp</wsu:Created> </wsse:UsernameToken> </wsse:Security> </soap:Header> Back-story: I'm integrating with a client application that is already built (and owned by another company). Basically this client application already has their soap messages all set up from its past integrations with other companies. So we've opted to just build a web service using an ASMX file that matches the WSDL that they're already setup to consume. Is it possible to get WS-Security working on an ASMX file or is ASMX too simplistic and I have to upgrade to WFC (which I really don't want to do)?

  • ASP.NET MVC BaseController to dynamically set MasterPage file

    - by rockinthesixstring
    I've built a Base Controller that all of my Controllers inherit from, and I've got it setup so that it checks the browser type and returns the appropriate MasterPageFile on the fly. I'm wondering if this is an efficient way to do this or if I should optimize it another way. Public Class BaseController : Inherits System.Web.Mvc.Controller Protected Overrides Function View(ByVal viewName As String, ByVal masterName As String, ByVal model As Object) As System.Web.Mvc.ViewResult If Request.Browser.IsMobileDevice Then Return MyBase.View(viewName, "Mobile", model) Else Return MyBase.View(viewName, "Site", model) End If End Function End Class

  • ASP.Net URL rewriting and redirecting....

    - by DDiVita
    I am trying to wrap my head around a URL rewrtie / redirect project I need to work on. We currently have this url: www.domain.com/Details/Detail.aspx?param1=8&param2=12345 Here is what the rewritten URL will look like: www.domain.com/Param1/8/Param2/12345 I am using the ISAPI_Rewrite filter to allow for the "nice" url and make the page think it is still using the old url. That works fine. Now, I need to redirect users, if they use the old URL, to the new URL. I fgiure I would need to use a combination of the filter and an HTTPModule / Handler to perfomr the redirect. Any ideas?

  • Usehttpget for script methods in config of asp.net web services

    - by Ajay
    Is there a way to put the usehttpget true/false option for scriptmethods in web.config? I see that even the scriptmethod annotations are placed inline with the code. Is there a way to move this to config as well? Ive seen usehttpget/post option in web.config for webservices but I need the same thing applicable for scriptservices.

  • Using ASP.NET Redirect without string URL?

    - by David Dietrich
    For instance, what I have right now is the following: Page.Response.Redirect("Default.aspx", false); Needing to hardcode the string just seems odd to me. The Default.aspx page is already in my project. So is there a way to do the redirect something like the following: Page.Response.Redirect(Default.aspx, false); Where Default.aspx is just the web form. I'd think that this way it would be obvious if there was a problem such as you deleted the web form but didn't update the redirects. Is this possible? Or is there another way entirely I should be looking at this? I suppose I could do something with a static property on the class, but I am wondering if there is a built in thing for this?

  • SharePoint 2010 / ASP.Net Integration - Looking for advice

    - by jpennal
    I have been Googling a problem that I have with trying to integrate the web application that I am working on with SharePoint 2010. The web application is a wiki style tool that allows users to log in via forms authentication or WIA against Active Directory and create content for themselves and others. What we would like to do is to allow a user have a page with the content they have created in our web application mixed in with content that they have living on the SharePoint server. For example, they may want to see a list of documents that they have on the SharePoint server mixed in with some of their content. To accomplish this, we would like to take the credentials the user has logged into our web application with (for example MYDOMAIN\jsmith) and be able to query SharePoint for the documents of that same user (MYDOMAIN\jsmith) WITHOUT the user being prompted to re-enter their credentials to access the SharePoint server (we are trying to avoid the double-hop problem) We have come up with some options for how we want to do this, but we are unsure of what the best approach is. For example, we could - Have a global user, shared by all users to get information we need from SharePoint. The downside is that we cannot filter SharePoint content to a particular user - We could store the users credentials when they log in, but that would only work for users authenticating via forms auth and would be a security issue that some users/clients would not like - Writing a SharePoint extension using WCF to allow us to access the information we need, however we'd still have the issue of figuring out how to impersonate the user we want. Neither of these options are ideal and in our investigation we came across the Claims Authentication/STS option which seems like it is trying to solve the problem we are having. So my question is, based on what I have written, is Claims/STS the best approach for us? We have not been able to find much direction on how to use this method to call into SharePoint from a Web Application and pass along the existing credentials. Does anyone have any experience with any of these issues?

  • ASP.NET MVC Custom Error Pages with Magical Unicorn

    - by FLClover
    my question is regarding Pure.Kromes answer to this post. I tried implementing my pages' custom error messages using his method, yet there are some problems I can't quite explain. a) When I provoke a 404 Error by entering in invalid URL such as localhost:3001/NonexistantPage, it defaults to the ServerError() Action of my error controller even though it should go to NotFound(). Here is my ErrorController: public class ErrorController : Controller { public ActionResult NotFound() { Response.TrySkipIisCustomErrors = true; Response.StatusCode = (int)HttpStatusCode.NotFound; var viewModel = new ErrorViewModel() { ServerException = Server.GetLastError(), HTTPStatusCode = Response.StatusCode }; return View(viewModel); } public ActionResult ServerError() { Response.TrySkipIisCustomErrors = true; Response.StatusCode = (int)HttpStatusCode.InternalServerError; var viewModel = new ErrorViewModel() { ServerException = Server.GetLastError(), HTTPStatusCode = Response.StatusCode }; return View(viewModel); } } My error routes in Global.asax.cs: routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.IgnoreRoute("{*favicon}", new { favicon = @"(.*/)?favicon.ico(/.*)?" }); routes.MapRoute( name: "Error - 404", url: "NotFound", defaults: new { controller = "Error", action = "NotFound" } ); routes.MapRoute( name: "Error - 500", url: "ServerError", defaults: new { controller = "Error", action = "ServerError" } ); And my web.config settings: <system.web> <customErrors mode="On" redirectMode="ResponseRewrite" defaultRedirect="/ServerError"> <error statusCode="404" redirect="/NotFound" /> </customErrors> ... </system.web> <system.webServer> <httpErrors errorMode="Custom" existingResponse="Replace"> <remove statusCode="404" subStatusCode="-1" /> <error statusCode="404" path="/NotFound" responseMode="ExecuteURL" /> <remove statusCode="500" subStatusCode="-1" /> <error statusCode="500" path="/ServerError" responseMode="ExecuteURL" /> </httpErrors> ... The Error views are located in /Views/Error/ as NotFound.cshtml and ServerError.cshtml. b) One funny thing is, When a server error occurs, it does in fact display the Server Error view I defined, however it also outputs a default error message as well saying that the Error page could not be found. Here's how it looks like: Do you have any advice how I could fix these two problems? I really like Pure.Kromes approach to implementing these error messages, but if there are better ways of achieving this don't hestitate to tell me. Thanks! *EDIT : * I can directly navigate to my views through the ErrorController by accessing /Error/NotFound or Error/ServerError. The views themselves only contain some text, no markup or anything. As I said, it actually works in some way, just not the way I intended it to work. There seems to be an issue with the redirect in the web.config, but I haven't been able to figure it out.

  • Dependency Injection Question - ASP.NET

    - by Paul
    I'm starting a web application that contains the following projects: Booking.Web Booking.Services Booking.DataObjects Booking.Data I'm using the repository pattern in my data project only. All services will be the same, no matter what happens. However, if a customer wants to use Access, it will use a different data repository than if the customer wants to use SQL Server. I have StructureMap, and want to be able to do the following: Web project is unaffected. It's a web forms application that will only know about the services project and the dataobjects project. When a service is called, it will use StructureMap (by looking up the bootstrapper.cs file) to see which data repository to use. An example of a services class is the error logging class: public class ErrorLog : IErrorLog { ILogging logger; public ErrorLog() { } public ErrorLog(ILogging logger) { this.logger = logger; } public void AddToLog(string errorMessage) { try { AddToDatabaseLog(errorMessage); } catch (Exception ex) { AddToFileLog(ex.Message); } finally { AddToFileLog(errorMessage); } } private void AddToDatabaseLog(string errorMessage) { ErrorObject error = new ErrorObject { ErrorDateTime = DateTime.Now, ErrorMessage = errorMessage }; logger.Insert(error); } private void AddToFileLog(string errorMessage) { // TODO: Take this value from the web.config instead of hard coding it TextWriter writer = new StreamWriter(@"E:\Work\Booking\Booking\Booking.Web\Logs\ErrorLog.txt", true); writer.WriteLine(DateTime.Now.ToString() + " ---------- " + errorMessage); writer.Close(); } } I want to be able to call this service from my web project, without defining which repository to use for the data access. My boostrapper.cs file in the services project is defined as: public class Bootstrapper { public static void ConfigureStructureMap() { ObjectFactory.Initialize(x => { x.AddRegistry(new ServiceRegistry()); } ); } public class ServiceRegistry : Registry { protected override void configure() { ForRequestedType<IErrorLog>().TheDefaultIsConcreteType<Booking.Services.Logging.ErrorLog>(); ForRequestedType<ILogging>().TheDefaultIsConcreteType<SqlServerLoggingProvider>(); } } } What else do I need to get this to work? When I defined a test, the ILogger object was null. Thanks,

  • Testing the context in asp.net mvc

    - by user252160
    I got pretty experienced with testing controllers, my question here is though, aren't we supposed to test the data context as well, and how ? I mean, there are a lot of relationships and constraints coming from the DB that simply testing controllers does not cover. On the other hand, testing against the DB is not considered a good practice - what then ? Simply testing without db.SubmitChanges() or what ?

  • Troubleshooting ASP .NET Application on Shared Hosting

    - by James
    Hi, My company has a CRM site hosted externally on a shared server and recently it has been very problematic. Users are being logged out randomly, sometimes only seconds after logging in. We are also getting viewstate validation errors at times. Both problems seem to occur more often when there are two or more people logged in at the same time, but I can't really see any particular pattern. I am using log4net to track the application state and from what I can tell it seems that the application is frequently restarting, causing all sorts of issues. I can see log messages from the Application_Start event handler but there is not always a corresponding message from the Application_End event handler. There is also logging code in the Application_Error event handler but it is not catching anything at the time of the restart. These errors started to occur soon after we moved our site to this shared server, although I don't remember it being this bad at first. Any advice on how to track down these problems would be appreciated. The server is running Windows Server 2003 and IIS 6.0. Sadly I don't have access to the server other than through Parallels Plesk and it doesn't seem to have any useful diagnostic information.

  • Issue Querying LDAP DirectoryEntry in ASP.NET

    - by davemackey
    I have users login to my application via Active Directory and then pull from their AD information to garner information about that user like so: Dim ID as FormsIdentity = DirectCast(User.Identity, FormsIdentity) Dim ticket as FormsAuthenticationTicket = ID.Ticket Dim adDirectory as New DirectoryEntry("LDAP://DC=my,DC=domain,DC=com") Dim adTicketID as String = ticket.Name.Substring(0, 5) Session("people_id") = adDirectory.Children.Find("CN=" & adTicketID).Properties("employeeID").Value Session("person_name") = adDirectory.Children.Find("CN=" & adTicketID).Properties("displayName").Value Now, I want to be able to impersonate other users...so that I can "test" the application as them, so I added a textbox and a button to the page and when the button is clicked the text is assigned to a session variable like so: Session("impersonate_user") = TextBox1.Text When the page reloads I check to see if Session("impersonate_user") has a value other than "" and then attempt to query Active Directory using this session variable like so: If CStr(Session("impersonate_user")) <> "" Then Dim adDirectory as New DirectoryEntry(LDAP://DC=my,DC=domain,DC=com") Dim adTicketID as String = CStr(Session("impersonate_user")) Session("people_id") = adDirectory.Children.Find("CN=" & adTicketID).Properties("employeeID").Value Session("person_name")= adDirectory.Children.Find("CN=" & adTicketID).Properties("displayName").Value Else [use the actual ticket.name to get this info.] End If But this doesn't work. Instead, it throws an error on the first Session line stating, "DirectoryServicesCOMException was unhandled by user code There is no such object on the server." Why? I know I'm giving it a valid username! Is something strange happening in the casting of the session? The code is essentially the same between each method except that in one method rather than pulling from ticket.Name I pull from a session variable for the login I'll be looking up with AD.

  • ASP.NET MVC does not add ModelError when invoking from unit test

    I have a model item public class EntryInputModel { ...

Why doesn't this work?
