  • Multiple Actions (Forms) on one Page - How not to lose master data, after editing detail data?

    - by nWorx
    Hello all, I've got a form where users can edit members of a group. So they have the possibilty to add members or remove existing members. So the Url goes like ".../Group/Edit/4" Where 4 is the id of the group. the view looks like this <% using (Html.BeginForm("AddUser", "Group")) %> <%{%> <label for="newUser">User</label> <%=Html.TextBox("username")%> <input type="submit" value="Add"/> </div> <%}%> <% using (Html.BeginForm("RemoveUser", "Group")) %> <%{%> <div class="inputItem"> <label for="groupMember">Bestehende Mitglieder</label> <%= Html.ListBox("groupMember", from g in Model.GetMembers() select new SelectListItem(){Text = g}) %> <input type="submit" value="Remove" /> </div> <%}%> The problem is that after adding or removing one user i lose the id of the group. What is the best solution for solving this kind of problem? Should I use hidden fields to save the group id? Thanks in advance.

  • How to dynamically set validation messages on properties with a class validation attribute

    - by Dan
    I'm writing Validation attribute that sits on the class but inspects the properties of the class. I want it to set a validation message on each of the properties it finds to be invalid. How do I do this? This is what I have got so far: [AttributeUsage(AttributeTargets.Class, AllowMultiple = false, Inherited = true)] public class LinkedFieldValidationAttribute : ValidationAttribute { private readonly string[] _properiesToValidate; public LinkedFieldValidationAttribute(params string[] properiesToValidate) { _properiesToValidate = properiesToValidate; } public override bool IsValid(object value) { PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(value); foreach (var propertyName in _properiesToValidate) { var propertyValue = properties.Find(propertyName, false).GetValue(value); //if value is invalid add message from base } //return validity } }

  • ListBoxFor not populating with selected items

    - by user576838
    I've see this question asked a couple of other times, and I followed this after I tried things on my own with the MS music store demo to no avail, but I still can't get this to work. I've also noticed when I look at my MultiSelectList object in the viewmodel, it has the correct items in the selected items property, but if I expand the results view, it doesn't have any listboxitem with the selected value. What am I missing here? I feel like I'm taking crazy pills! Thanks in advance. model: public class Article { public int ArticleID { get; set; } public DateTime? DatePurchased { get; set; } public DateTime? LastWorn { get; set; } public string ThumbnailImg { get; set; } public string LargeImg { get; set; } public virtual List<Outfit> Outfits { get; set; } public virtual List<Tag> Tags { get; set; } } viewmodel: public class ArticleViewModel { public int ArticleID { get; set; } public List<Tag> Tags { get; set; } public MultiSelectList mslTags { get; set; } public virtual Article Article { get; set; } public ArticleViewModel(int ArticleID) { using (ctContext db = new ctContext()) { this.Article = db.Articles.Find(ArticleID); this.Tags = db.Tags.ToList(); this.mslTags = new MultiSelectList(this.Tags, "TagID", "Name", this.Article.Tags); } } } controller: public ActionResult Index() { ArticleIndexViewModel vm = new ArticleIndexViewModel(db); return View(vm); } view: @model ClosetTracker.ArticleViewModel @using (Html.BeginForm()) { <img id="bigImg" src="@Model.Article.ThumbnailImg" alt="img" /> @Html.HiddenFor(m => m.ArticleID); @Html.LabelFor(m => m.Article.Tags) @* @Html.ListBoxFor(m => m.Article.Tags, Model.Tags.Select(t => new SelectListItem { Text = t.Name, Value = t.TagID.ToString() }), new { Multiple = "multiple" }) *@ @Html.ListBoxFor(m => m.Article.Tags, Model.mslTags); @Html.LabelFor(m => m.Article.LastWorn) @Html.TextBoxFor(m => m.Article.LastWorn, new { @class = "datepicker" }) @Html.LabelFor(m => m.Article.DatePurchased) @Html.TextBoxFor(m => m.Article.DatePurchased, new { @class = "datepicker" }) <p> <input type="submit" value="Save" /> </p> } EDITED Ok, I changed around the constructor of the MultiSelectList to have a list of TagID in the selected value arg instead of a list of Tag objects. This shows the correct tags as selected in the results view when I watch the mslTags object in debug mode. However, it still isn't rendering correctly to the page. public class ArticleViewModel { public int ArticleID { get; set; } public List<Tag> Tags { get; set; } public MultiSelectList mslTags { get; set; } public virtual Article Article { get; set; } public ArticleViewModel(int ArticleID) { using (ctContext db = new ctContext()) { this.Article = db.Articles.Find(ArticleID); this.Tags = db.Tags.ToList(); this.mslTags = new MultiSelectList(this.Tags, "TagID", "Name", this.Article.Tags.Select(t => t.TagID).ToList()); } } }

  • Conditionally embed ASP.NET MVC2 Views as resources during build in Visual Studio 2010

    - by jslatts
    I have a ASP.NET MVC2 project in VS2010 that can be deployed in two modes: standalone or plugin. In standalone mode, the views should live outside the compiled assembly as .aspx files (the default setup). In plugin mode, the views are switched (currently by hand) to embedded resources and the entire assembly is dropped into a host project folder. Currently, this requires the developer to go through each view and switch it from Build Action: "Content" to "Embedded Resource" and vice versa. I would like to create a new solution configuration to automatically grab all .aspx files and build them as resources. This SO post seems like the solution, but I would prefer not to have to edit the .csproj every single time I add a new view to the project. Is there a way to use a wild cards or some other batch/global conditionally statement to change resources from content to embedded?

  • Caching asp.net viewdata

    - by Tomh
    Hey guys, I'm currently thinking about caching most of my viewdata excpt user specific data after a user logs on. I thought the simplest way was caching the ViewData object itself and adding the user specific data after it was loaded. Are there any downsides of this approach? Are there better ways? string cacheKey = "Nieuws/show/" + id; if (HttpRuntime.Cache[cacheKey] != null) { ViewData = HttpRuntime.Cache[cacheKey] as ViewDataDictionary; } else { // add stuff to view data HttpRuntime.Cache.Insert(cacheKey, ViewData, null, DateTime.Now.AddSeconds(180), Cache.NoSlidingExpiration, CacheItemPriority.NotRemovable, null); }

  • Does UserId data type affect FormsAuthentication.SetAuthCookie(UserId.ToString(), false)?

    - by FreshCode
    Does the original data type of the username string in a call to FormsAuthentication.SetAuthCookie(...) make any difference with regards to security or code maintainability? As I understand it, the cookie is encrypted and used to identify a user on each request. I'm curious whether it should affect the design of the primary key on my Users table in my database, eg. Guid vs int or a unique username string.

  • spring-nullpointerexception- cant access autowired annotated service (or dao) in a no-annotations class

    - by user286806
    I have this problem that I cannot fix. From my @Controller, i can easily access my autowired @Service class and play with it no problem. But when I do that from a separate class without annotations, it gives me a NullPointerException. My Controller (works)- @Controller public class UserController { @Autowired UserService userService;... My separate Java class (not working)- public final class UsersManagementUtil { @Autowired UserService userService; or @Autowired UserDao userDao; userService or userDao are always null!

  • Java Web Application on Tomcat - Displaying a File Uploaded by User

    - by walnutmon
    I need to display uploaded files on a web application, the flow is as follows User uploads file through web UI Validation on image Makes call to imageRepository.store( uploadedImage, user.getSite() ) The user wants the image displayed which adds <img src="${anUploadedImage.getUrl()}"/> but that is where I'm stuck, what can getUrl() do? The simple solution is to put it someplace and let Apache serve the file, but then I can't use the application to ensure that one user isn't modifying the URL to view other users files, which in this case is important

  • Moq.Mock<T> - how to setup a method that takes an expression

    - by Paul
    I am Mocking my repository interface and am not sure how to setup a method that takes an expression and returns an object? I am using Moq and NUnit Interface: public interface IReadOnlyRepository : IDisposable { IQueryable<T> All<T>() where T : class; T Single<T>(Expression<Func<T, bool>> expression) where T : class; } Test with IQueryable already setup, but don't know how to setup the T Single: private Moq.Mock<IReadOnlyRepository> _mockRepos; private AdminController _controller; [SetUp] public void SetUp() { var allPages = new List<Page>(); for (var i = 0; i < 10; i++) { allPages.Add(new Page { Id = i, Title = "Page Title " + i, Slug = "Page-Title-" + i, Content = "Page " + i + " on page content." }); } _mockRepos = new Moq.Mock<IReadOnlyRepository>(); _mockRepos.Setup(x => x.All<Page>()).Returns(allPages.AsQueryable()); //Not sure what to do here??? _mockRepos.Setup(x => x.Single<Page>() //---- _controller = new AdminController(_mockRepos.Object); }

  • Unable to step into interface implementation configured by unity application block

    - by Rahul
    I have configured a set of interface implementations with EntLib. unity block. The constructor of implementation classes work fine as soon as I run the application: 1. The interface to implement when I run the application the cctor runs fine, which shows that unity resolution was successful: But when I try to call a method of this class, the code just passes through without actually invoking the function of the implemented class: Edit: Added on June 11, 2012 Following is the Unity Configuration I have. (This is all the unity configuration I am doing) public class UnityControllerFactory : DefaultControllerFactory { private static readonly IUnityContainer container; private static UnityControllerFactory factory = null; static UnityControllerFactory() { container = new UnityContainer(); UnityConfigurationSection section = (UnityConfigurationSection)ConfigurationManager.GetSection("unity"); section.Configure(container); factory = new UnityControllerFactory(); } public static UnityControllerFactory GetControllerFactory() { return factory; } protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) { return container.Resolve(controllerType) as IController; } } I am unable to step into this code and the implementation simply skips out without executing anything. What is wrong here?

  • Possible to write an Extension Method for ASP.NET's Html.ActionLink() method?

    - by Pretzel
    Right now, I'm trying to work around an IE6/7 bug which requires the wrapping of the </a closing tag with this IE specific comment to make some drop-down menu work: <!--[if IE 7]><!--></a><!--<![endif]--> Unfortunately, I cannot inject this directly into my View page code like this: <%= Html.ActionLink("LinkName<!--[if IE 7]><!--></a><!--<![endif]-->","Action","Controller") %> As Html.ActionLink will do the safe thing and filter out the comment to prevent a Javascript injection attack. Ok, cool. I'm fine with that. Good design decision. What I'd like to do is write an Extension Method to this, but the process is eluding me as I haven't done this before. I thought this would work, but Intellisense doesn't seem to be picking up this Extension method that I've written. public static class MyLinkExtensions { public static string ActionLinkIE(this HtmlHelper htmlHelper, string linkText, string actionName, string controllerName) { return LinkExtensions.ActionLink(htmlHelper, linkText, actionName, controllerName). Replace(@"</a>", @"<!--[if IE 7]><!--></a><!--<![endif]-->"); } } Any suggestions?

  • radiobutton checked on condition in jquery

    - by RememberME
    I have the following fields: <label>Company Type:</label> <label for="primary"><input onclick="javascript: $('#sec').hide('slow');$('#primary_company').find('option:first').attr('selected','selected');" type="radio" runat="server" name="companyType" id="primary" />Primary</label> <label for="secondary"><input onclick="javascript: $('#sec').show('slow');" type="radio" runat="server" name="companyType" id="secondary" />Secondary</label> <div id="sec"> <fieldset> <label for="primary_company">Primary Company:</label> <%= Html.DropDownList("primary_company", Model.SelectPrimaryCompanies, "** Select Primary Company **") %> </fieldset> If there is a primary_company, then the secondary radio button should be selected. If there is no primary_company, then the primary radio button should be selected. Here is my jQuery: $(document).ready(function() { if ($('#primary_company').val().length > 0) { $('#secondary').attr({ checked: true }); } else { $("#primary").attr('checked', true ); $('#sec').hide(); } The sec div hides and shows properly, but a radio button is never selected. I've tried .attr('checked', 'checked') and .attr({ checked: true }) and .attr('checked', true) but nothing is ever selected.

  • Session is Closed! NHibernate shouldn't be trying to grab data

    - by Jeremy Holovacs
    I have a UnitOfWork/Service pattern where I populate my model using NHibernate before sending it to the view. For some reason I still get the YSOD, and I don't understand why the object collection is not already populated. My controller method looks like this: public ActionResult PendingRegistrations() { var model = new PendingRegistrationsModel(); using (var u = GetUnitOfWork()) { model.Registrations = u.UserRegistrations.GetRegistrationsPendingAdminApproval(); } return View(model); } The service/unit of work looks like this: public partial class NHUserRegistrationRepository : IUserRegistrationRepository { public IEnumerable<UserRegistration> GetRegistrationsPendingAdminApproval() { var r = from UserRegistration ur in _Session.Query<UserRegistration>() where ur.Status == AccountRegistrationStatus.PendingAdminReview select ur; NHibernateUtil.Initialize(r); return r; } } What am I doing wrong?

  • How to add reference an assembly that is not in the GAC from a t4mvc template (.tt)

    - by stephen
    I have found the place near the very top in a T4MVC template file (.tt) where assembly references can be added, which looks like: <#@ assembly name="System.Core" #> <#@ import namespace="System.Collections.Generic" #> However, it seems that I can only reference assemblies that are in the GAC. i.e. if I have an assembly MyProject.Stuff.dll (not in the GAC) added as a reference to the VS project containing the template then I expected to be able to add something like the following: <#@ assembly name="MyProject.Stuff" #> <#@ import namespace="MyProject.Stuff" #> If I do this then I get the following error: Error 1 Compiling transformation: Metadata file 'MyProject.Stuff' could not be found C:\Work\Development\DotNetSolution\MyProject\Utils\T4MVC\T4MVC.tt 1 1 How can I add a reference to an assembly that isn't in the GAC?

  • Why are my connections not closed even if I explicitly dispose of the DataContext?

    - by Chris Simpson
    I encapsulate my linq to sql calls in a repository class which is instantiated in the constructor of my overloaded controller. The constructor of my repository class creates the data context so that for the life of the page load, only one data context is used. In my destructor of the repository class I explicitly call the dispose of the DataContext though I do not believe this is necessary. Using performance monitor, if I watch my User Connections count and repeatedly load a page, the number increases once per page load. Connections do not get closed or reused (for about 20 minutes). I tried putting Pooling=false in my config to see if this had any effect but it did not. In any case with pooling I wouldn't expect a new connection for every load, I would expect it to reuse connections. I've tried putting a break point in the destructor to make sure the dispose is being hit and sure enough it is. So what's happening? Some code to illustrate what I said above: The controller: public class MyController : Controller { protected MyRepository rep; public MyController () { rep = new MyRepository(); } } The repository: public class MyRepository { protected MyDataContext dc; public MyRepository() { dc = getDC(); } ~MyRepository() { if (dc != null) { //if (dc.Connection.State != System.Data.ConnectionState.Closed) //{ // dc.Connection.Close(); //} dc.Dispose(); } } // etc } Note: I add a number of hints and context information to the DC for auditing purposes. This is essentially why I want one connection per page load
