  • How to update model in the database, from asp.net MVC2, using Entity Framework?

    - by Eedoh
    Hello. I'm building ASP.NET MVC2 application, and using Entity Framework as ORM. I am having troubles updating object in the database. Every time I try entity.SaveChanges(), EF inserts new line in the table, regardless of do I want update, or insert to be done. I tried attaching (like in this next example) object to entity, but then I got {"An object with a null EntityKey value cannot be attached to an object context."} Here's my simple function for inserts and updates (it's not really about vehicles, but it's simpler to explain like this, although I don't think that this effects answers at all)... public static void InsertOrUpdateCar(this Vehicles entity, Cars car) { if (car.Id == 0 || car.Id == null) { entity.Cars.AddObject(car); } else { entity.Attach(car); } entitet.SaveChanges(); } I even tried using AttachTo("Cars", car), but I got the same exception. Anyone has experience with this?

  • ASP.NET MVC:Why does the CheckBoxFor render an additional input tag and how can I get the value usin

    - by Nikron
    Hi, In my ASP.NET MVC app I am rendering out a checkbox using the following code: <%= Html.CheckBoxFor(i=>i.ReceiveRSVPNotifications) %> Now I see that this renders both the checkbox input tag and a hidden input tag. The problem that I am having is when I try retrieve the value from the checkbox using the FormCollection: FormValues["ReceiveRSVPNotifications"] I get the value "true,false". When looking at the rendered out HTML I can see the following: <input id="ReceiveRSVPNotifications" name="ReceiveRSVPNotifications" value="true" type="checkbox"> <input name="ReceiveRSVPNotifications" value="false" type="hidden"> So the FormValues collection seems to join these two values since they have the same name. Any Ideas?

    - by Rita
    Hi I have a customer Registartion page using ASP.NET MVC with fields like FirstName, LastName, Address from AddressDetail Table. When i create a new object for CustomerMaster and trying to update the fields using TryUpdateModel, it is not updating. But the TryUpdateModel is working fine on the Edit Profile Page and that particular record is referenced. CODE on Registartion Page: AddressDetail add = new AddressDetail(); bool status = TryUpdateModel<AddressDetail>(add, "addr", new[] { "FirstName", "LastName", "Address_1", "Address_2", "ZipCode", "City", "Phone", "Fax" }, formData); CODE on Edit Profile Page: AddressDetail addr = (from a in miEntity.AddressDetail where a.AD_Id == 20 select a).First(); bool rc = TryUpdateModel<AddressDetail>(addr, "addr", new[] { "FirstName", "LastName", "Address_1", "Address_2", "ZipCode", "City", "Phone", "Fax" }, formData); Does anybody run into same issue with TryUpdateModel? Doesn't it update the Model for New Record? Thanks

  • Passing parameter to SOAP Web Service Requests Using Visual Studio Team System 2008

    - by Nicholas
    How can I pass in the current datetime parameter to a SOAP request? I know you can pass in parameters by adding a datasource to the web test project and reference it like this {{DataSource.TableName.FieldName}}. But I want to pass in current datetime parameter as a dynamic value (something like DateTime.Now). How do I go about doing this? Below is sample SOAP request that I put into String Body: <soap:body> <MyQuery xmlns="http://something.com"> <req> <QueryType>{{DataSource.Table.QueryType}}</QueryType> <Name>{{DataSource.Table.Name}}</Name> <RequestDateTime>{{insert DateTime.Now here}}</RequestDatetime> </req> </MyQuery> </soap:body> P.S.

  • Does the DataAnnotations.DisplayAttribute.Order property not work with ASP.NET MVC 2?

    - by Zack Peterson
    I set values for the Order property of the Display attribute in my model metadata. [MetadataType(typeof(OccasionMetadata))] public partial class Occasion { private class OccasionMetadata { [ScaffoldColumn(false)] public object Id { get; set; } [Required] [DisplayName("Title")] [Display(Order = 0)] public object Designation { get; set; } [Required] [DataType(DataType.MultilineText)] [Display(Order = 3)] public object Summary { get; set; } [Required] [DataType(DataType.DateTime)] [Display(Order = 1)] public object Start { get; set; } [Required] [DataType(DataType.DateTime)] [Display(Order = 2)] public object Finish { get; set; } } } I present my models in strongly-typed views using the DisplayForModel and EditorForModel methods. <%= Html.DisplayForModel() %> and <%= Html.EditorForModel() %> But, ASP.NET MVC 2 displays the fields out of order! What might I have wrong?

  • Why is my asp:Substitution control suddenly not working in ASP.NET 4.0?

    - by Steve Wortham
    I just upgraded my site from ASP.NET 3.5 to 4.0. I've been working through some breaking changes and there were more than I expected. One I can't figure out, however, is why my <asp:Substitution /> control suddenly stopped working like it should. It's supposed to ignore the output cache settings of the parent page and update upon every request. For some reason that isn't happening. It's caching for the full 10 minutes (the OutputCache setting for my home page). Any ideas?

  • Can I retrieve data from server to client during an asynchronous post-back using ASP.NET Ajax Librar

    - by André Pena
    ASP.NET Ajax Library provides some client-side events. For instance: Sys.Application.add_load( function(args) { // handle the end of any asynchronous post-back. Every-time there's // a server round-trip, this method will be called. } ); During the asynchronous post-back I want to retrieve information to the client. This information must be available in some event like the discribed above. Does the UpdatePanel or the ScriptManager have any server-side way to retrieve data back to client during an asynchronous post-back?

  • How can I make this Route (ASP.Net MVC2) ?

    - by Felipe
    Hi All, I'm begginer in asp.net mvc and I have some doutbs about routes. Im' developing a system to manage documents and I need make an URL like this: routes.MapRoute("Documentos", "{controller}/{documentType}/{documento}/{action}/{id}", new { controller = "Home", documentType = "", documento = "", action = "Index", id = UrlParameter.Optional }); and the app working an URL like theses: "Document/Administrative/Contract" - (Index action by default to list documents of type 'Contract') "Document/Administrative/Contract/New" - (new action in controller) "Document/Administrative/Contract/10" - (detail action in controller) "Document/Administrative/Contract/Edit/10" - (edit action in controller) Document would be a Controller, and Administrative would be just a description in url to identify that documents of 'Contract' is Administrative... So, My doubts is about my controllers and actions, How should be the signature of the methods of controller ? Need I make an Area called Documents to do this more easy ? PS: Sorry for my english! Thanks a lot, Cheers! Felipe

  • PHP voting system with sessions?

    - by pingu
    Hi guys, I've been reading up on stackoverflow about creating voting systems in PHP that minimize abuse/multiple voting from the same user, but I haven't come across the answer to my question. I've got an application where users don't need to register to vote or "like" an entry. Obviously, I want to minimize abuse and I don't want to limit votes per IP address because some organisations (mine included) use shared IP addresses. I've never used sessions in a non-authenticated system before, but since this application is centered around entry votes I was wondering if this approach would work and whether there were any disadvantages such as performance implications, and whether it's even possible to use sessions in this way: start a session when the website is loaded allow one vote per item per session If this is a bad idea, my alternative options would be to allow a reasonable number of votes per IP address (say 25), or put a time limit between votes from the same IP address. What do you guys recommend?

  • Call up last exception on an ASP.NET error page.

    - by Aren B
    I've got an error page here SiteError.aspx and it's configured correctly in the web.config to go there when unhandled exceptions are encountered. I want to use this page to log the exception that triggered it as well because I only want to LOG the errors that the users encounter (i.e. if SiteError.aspx is ever hit.) This is the code I Have: In the OnLoad(...) in SiteError.aspx Exception lastEx = Context.Server.GetLastError(); if (lastEx != null) log.Error("A site error was encountered", lastEx); However, my log is never showing up in my Output, and If i breakpoint on line 2 (in this example) code execution is never interupted (after letting the exception clear to ASP.NET handling in the debugger.

    Say I have a controller called "HomeController" which inherits from Mvc.Controller. Also say I have written the constructor of the controller and some filters for some actions. Public Class ClientController Inherits System.Web.Mvc.Controller Public Sub New() ''Some code End Sub <SomeActionFilter()> _ Function Index() As ActionResult Return View() End Function End Class My questions are : What is the order of execution of constructor, filter, action? Can I have a filter for the Constructor, if I do not want to run the code in it by checking for some conditions?

  • It is okay to migrate to Asp.NET 4.0 now?

    - by Tarik
    Okay today, as most of you noticed Framework 4.0 has been released. I've been working on a project which is being built on framework 3.5. Since I want to use dynamic keyword and most of the asp.net features like Tableless Menu Control, ClientIDMode and clean web.config etc. I am kinda urging to migrate the unfinished project to 4.0 but I am little hesitating about that.Some times I think it is way better to wait for SP1. So what do you think about it? You guys will migrate to unfinished projects or will still hang out with 3.5 for a while. Thanks.

  • How powerful is the <script> tag in ASP.NET ?

    - by MarceloRamires
    I'm new at web development with .NET, and I'm currently studying a page where I have both separated codebehinds (in my case, a .CS file associated to the ASPX file), and codebehind that is inside the ASPX file inside tags like this: <script runat="server"> //code </script> Q1:What is the main difference (besides logical matters like organization, readability and ETC), what could be done in one way that could not be done in another? What is each mode best suited for ? Q2:If I'm going to develop a simple page with database connection, library imports, access to controls (ascx) and image access in other folders.. which method should I choose ?

  • alternatives to System.Diagnostics.Process.Start when command is too long

    - by Frank Schwieterman
    I have some code which is generating a rather long command that is being sent to System.Diagnostics.Process.Start(). The call fails with a Win32Exception, message "The filename or extension is too long". The path to the program itself is not very long, but the parameters passed in are quite long. I am calling the version where an instance of ProcessStartInfo is passed as the parameter, and in this case its the ProcessStartInfo.Arguments .Field that is very long. (other parameters: CreateNoWindow = true, UseShellExecute = false, RedirectStandardError = true). It looks like the exception is coming from a call to win32 function CreateProcess. Does anyone have an idea of another way to start the process?

  • Should I replace string patterns in asp.net mvc using a custom viewengine?

    - by Roger Rogers
    Have an ASP.NET MVC site that is localized. The localization functionality adds the two digit language ID to the URL, e.g. /es/Page. If no language Id is found in the URL, the site switches to the user's browser culture. All's good. However, the site's hyperlinks, a mixture of hard-coded href tags, actionlinks, etc., don't include the base language ID, so when clicking through the site the set culture is lost, and the site reverts to the user's browser culture. My (lazy) thought is to replace all href values, that don't point to an external site, with the localized URL (e.g. include the /es/). Otherwise, all site links will need to be updated to include the culture code. Is this just plain dumb? Or, reasonable, and should be done using a custom view engine, or some other approach?

  • What does the "ApplicaionDirectory" Membership condition mean in .NET Code Access Security?

    - by smwikipedia
    I am not sure about the semantic of "ApplicationDirectory" membership condition. I am trying to use it in the .NET Framework 2.0 configuration tool. The tool's explanation to it is as below: The Application Directory membership condition is true for all assemblies in the same directory or in a child directory of the running application. Assemblies that meet this membership condition will be granted the permissions associated with this code group. All the other membership conditions such as strong name, hash, need me to input some criterias, only the Application Directory has not. How to use it? Could someone give an explanation by example? Many thanks.

  • How to retarget the scroll wheel in VB.Net?

    - by Orborde
    I have a form in VB.Net with Autoscroll enabled and several ComboBoxes within it. When I click on a ComboBox, I can use the mouse wheel to scroll through options, but I cannot deselect the ComboBox (by clicking off it on a blank portion of the parent form) in order to return to scrolling the parent form. This makes navigation in the form annoying, as I instinctively click off the control and flip the scroll wheel, causing the ComboBox to change selections instead of moving the parent form. Is there a way to make this work in the intuitive way I expect it to, or do I have some conceptual confusion that makes this the wrong question to ask?

  • Using the ASP.NET membership provider database with your own database?

    - by Shaharyar
    Hello everybody, We are developing an ASP.NET MVC Application that currently uses it's own databse ApplicationData for the domain models and another one Membership for the user management / membership provider. We do access restrictions using data-annotations in our controllers. [Authorize(Roles = "administrators, managers")] This worked great for simple use cases. As we are scaling our application our customer wants to restrict specific users to access specific areas of our ApplicationData database. Each of our products contains a foreign key referring to the region the product was assembled in. A user story would be: Users in the role NewYorkManagers should only be able to edit / see products that are assembled in New York. We created a placeholder table UserRightsRegions that contains the UserId and the RegionId. How can I link both the ApplicationData and the Membership databases in order to work properly / having cross-database-key-references? (Is something like this even possible?) All help is more than appreciated!

  • How to create a asp.net membership provider hashed password manually?

    - by Anheledir
    I'm using a website as a frontend and all users are authenticated with the standard ASP.NET Membership-Provider. Passwords are saved "hashed" within a SQL-Database. Now I want to write a desktop-client with administrative functions. Among other things there should be a method to reset a users password. I can access the database with the saved membership-data, but how can I manually create the password-salt and -hash? Using the System.Web.Membership Namespace seems to be inappropriate so I need to know how to create the salt and hash of the new password manually. Experts step up! :)
