  • ASP.Net MVC2 Client and Server Validation sharing the same code - is it possible?

    - by RemotecUk
    With the excellent XVal by Steve Sanderson, it is possible to tell the client side validation to post the value being validated to the server using jquery. A method on the server then uses the same server side code you use for your server side validation, and returns simply a true or false to determine if the field is valid. The advantage of this method is that you write your complex validation logic once in C# code and then put some JQuery plumbing in to tell your client page where to go to access your server validation. I have been reading some blogs on MVC2 but no one seems to mention this functionality. Is it possible to tell the Microsoft MVC validation javascript to call a url validate data? Or do you have to write your own client side validation routines. I should note that using the xVal method a custom validation to say if an email address is in use or not can be run from the client via a JQuery post which accesses the server side validation logic.

  • ASP.NET MVC Users unable to login after password change, and being locked out.

    - by Russell Kay
    All, I have a website that is in use and has several users, using the MySqlMembershipProvider. We have had a few users that have been locked out (for some reason) and recently I unlocked them and reset the passwords, using the MembershipUser.UnlockUser and MembershipUser.ResetPassword methods. Now they are definitely marked in the database as Unlocked and the password has been reset, but they still cannot log in. Does anyone have any ideas why this might happen?

  • ASP.NET MVC - Data Annotations - Why add a default RequiredAttribute?

    - by redsquare
    Can anyone explain why it is assumed that a non nullable type property should always have a RequiredAttribue? I am trying to write a label helper that will auto append * or change the css class so that I can indicate to the user that the field is required. However when querying the metadata the non nullable properties end up with a required attribute. MVC Source Code: protected override IEnumerable<ModelValidator> GetValidators( ModelMetadata metadata, ControllerContext context, IEnumerable<Attribute> attributes) { _adaptersLock.EnterReadLock(); try { List<ModelValidator> results = new List<ModelValidator>(); if (metadata.IsRequired && !attributes.Any(a => a is RequiredAttribute)) { //******* Why Do this? attributes = attributes.Concat(new[] { new RequiredAttribute() }); } foreach (ValidationAttribute attribute in attributes.OfType<ValidationAttribute>()) { DataAnnotationsModelValidationFactory factory; if (!_adapters.TryGetValue(attribute.GetType(), out factory)) factory = _defaultFactory; results.Add(factory(metadata, context, attribute)); } return results; } finally { _adaptersLock.ExitReadLock(); } }

  • Asp.net HttpWebResponse - how can I not depend on WebException for flow control?

    - by Campos
    I need to check whether the request will return a 500 Server Internal Error or not (so getting the error is expected). I'm doing this: HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest; request.Method = "GET"; HttpWebResponse response = request.GetResponse() as HttpWebResponse; if (response.StatusCode == HttpStatusCode.OK) return true; else return false; But when I get the 500 Internal Server Error, a WebException is thrown, and I don't want to depend on it to control the application flow - how can this be done?

  • How can I highlight empty fields in ASP.NET MVC 2 before model binding has occurred?

    - by Richard Poole
    I'm trying to highlight certain form fields (let's call them important fields) when they're empty. In essence, they should behave a bit like required fields, but they should be highlighted if they are empty when the user first GETs the form, before POST & model validation has occurred. The user can also ignore the warnings and submit the form when these fields are empty (i.e. empty important fields won't cause ModelState.IsValid to be false). Ideally it needs to work server-side (empty important fields are highlighted with warning message on GET) and client-side (highlighted if empty when losing focus). I've thought of a few ways of doing this, but I'm hoping some bright spark can come up with a nice elegant solution... Just use a CSS class to flag important fields Update every view/template to render important fields with an important CSS class. Write some jQuery to highlight empty important fields when the DOM is ready and hook their blur events so highlights & warning messages can be shown/hidden as appropriate. Pros: Quick and easy. Cons: Unnecessary duplication of importance flags and warning messages across views & templates. Clients with JavaScript disabled will never see highlights/warnings. Custom data annotation and client-side validator Create classes similar to RequiredAttribute, RequiredAttributeAdapter and ModelClientValidationRequiredRule, and register the adapter with DataAnnotationsModelValidatorProvider.RegisterAdapter. Create a client-side validator like this that responds to the blur event. Pros: Data annotation follows DRY principle (Html.ValidationMessageFor<T> picks up field importance and warning message from attribute, no duplication). Cons: Must call TryValidateModel from GET actions to ensure empty fields are decorated. Not technically validation (client- & server-side rules don't match) so it's at the mercy of framework changes. Clients with JavaScript disabled will never see highlights/warnings. Clone the entire validation framework It strikes me that I'm trying to achieve exactly the same thing as validation but with warnings rather than errors. It needs to run before model binding (and therefore validation) has occurred. Perhaps it's worth designing a similar framework with annotations like Required, RegularExpression, StringLength, etc. that somehow cause Html.TextBoxFor<T> etc. to render the warning CSS class and Html.ValidationMessageFor<T> to emit the warning message and JSON needed to enable client-side blur checks. Pros: Sounds like something MVC 2 could do with out of the box. Cons: Way too much effort for my current requirement! I'm swaying towards option 1. Can anyone think of a better solution?

  • ASP.NET MVC: How to transfer more than one object to View method?

    - by ile
    I finished NerdDinner tutorial and now I'm playing a bit with project. Index page shows all upcoming dinners: public ActionResult Index() { var dinners = dinnerRepository.FindUpComingDinners().ToList(); return View(dinners); } In DinnerRepository class I have method FindAllDinners and I would like to add to above Index method number of all dinners, something like this: public ActionResult Index() { var dinners = dinnerRepository.FindUpComingDinners().ToList(); var numberOfAllDinners = dinnerRepository.FindAllDinners().Count(); return View(dinners, numberOfAllDinners); } Of course, this doesn't work. As I'm pretty new to OOP I would need help with this one. Thanks, Ile

  • How to track changes in many MSSQL databases from .NET application?

    - by Yauheni Sivukha
    Problem: There are a lot of different databases, which is populated by many different applications directly (without any common application layer). Data can be accessed only through SP (by policy) Task: Application needs to track changes in these databases and react in minimal time. Possible solutions: 1) Create trigger for each table in each database, which will populate one table with events. Application will watch this table through SqlDependency. 2) Watch each table in each database through SqlDependency. 3) Create trigger for each table in each database, which will notify application using managed extension. Which is the best way?

  • What is the correct way to create dynamic javascript in ASP.net MVC2?

    - by sabbour
    I'm creating a Google Maps partial view/user control in my project that is passed a strongly typed list of objects containing latitude and longitude values. Currently, this is the code I have for the partial: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<Project.Models.Entities.Location>>" %> <!-- Place for google to put the map --> <div id="report_map_canvas" style="width: 100%; height: 728px; margin-bottom: 2px;"> </div> <script type='text/javascript'> google.load("maps", "2"); $(document).ready(initializeMap); function initializeMap() { if (GBrowserIsCompatible()) { var map = new GMap2(document.getElementById('report_map_canvas')); map.setCenter(new GLatLng(51.5, -0.1167), 2); <% foreach (var item in Model) { %> map.addOverlay(new GMarker(new GLatLng('<%= Html.Encode(item.latitude)%>','<%= Html.Encode(item.longitude)%>'),{ title: '<%= Html.Encode(String.Format("{0:F}",item.speed)) %> km/h '})); <% } %> map.setUIToDefault(); } } </script> Is it right to dynamically create the javascript file this way by looping over the list and emitting javascript? Is there a better way to do it?

  • ASP.NET - How to add a label to a RadioButtonList ListItem?

    - by EWizard
    I have a RadioButtonList with two ListItems included: <asp:RadioButtonList runat="server" ID="optRollover" OnSelectedIndexChanged="RolloverOptionSelected" AutoPostBack="true"> <asp:ListItem Value="0">100% </asp:ListItem> <asp:ListItem Value="1">Less than 100%</asp:ListItem> </asp:RadioButtonList><br /> On the first ListItem I need to have a label that displays some text from the code behind of the page. Logically it seems to me like I would be able to do something like this: 100% Obviously this does not work because I am getting an error: The 'Text' property of 'asp:ListItem' does not allow child objects. Can anyone think of a way around this constraint?

  • How can I include additional markup within a 'Content' inner property within an ASP.Net WebControl?

    - by GenericTypeTea
    I've searched the site and I cannot find a solution for my problem, so apologies if it's already been answered (I'm sure someone must have asked this before). I have written a jQuery Popup window that I've packaged up as a WebControl and IScriptControl. The last step is to be able to write the markup within the tags of my control. I've used the InnerProperty attribute a few times, but only for including lists of strongly typed classes. Here's my property on the WebControl: [PersistenceMode(PersistenceMode.InnerProperty)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] public something??? Content { get { if (_content == null) { _content = new something???(); } return _content; } } private something??? _content; Here's the HTML Markup of what I'm after: <ctr:WebPopup runat="server" ID="win_Test" Hidden="false" Width="100px" Height="100px" Modal="true" WindowCaption="Test Window" CssClass="window"> <Content> <div style="display:none;"> <asp:Button runat="server" ID="Button1" OnClick="Button1_Click" /> </div> <%--Etc--%> <%--Etc--%> </Content> </ctr:WebPopup> Unfortunately I don't know what type my Content property should be. I basically need to replicate the UpdatePanel's ContentTemplate. EDIT: So the following allows a Template container to be automatically created, but no controls show up, what's wrong with what I'm doing? [PersistenceMode(PersistenceMode.InnerProperty)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] public ITemplate Content { get { return _content; } set { _content = value; } } private ITemplate _content;

  • How does "Require SSL" affect ASP.NET MVC application lifecycle?

    - by Ragesh
    I have an application that taps into BeginRequest and EndRequest to set up and tear down NHibernate sessions like this: BeginRequest += delegate { CurrentSessionContext.Bind(SessionFactory.OpenSession()); }; EndRequest += delegate { var session = CurrentSessionContext.Unbind(SessionFactory); session.Dispose(); Container.Release(session); }; This works fine when deployed in IIS, until I check the "Require SSL" box. Once I do this, I get a NullReferenceException at session.Dispose(). I haven't debugged this yet and, yes, the fix is trivial, but I'm just curious about how "Require SSL" affects the lifecycle of a request. Is a session not set up on the server in these cases?

  • asp.net form validation. Server-side or client-side

    - by Jeroen
    Here's (i think) an interesting question. With AJAX more and more common i feel more and more like doing all form validation server-side. Picture a registration form pre-AJAX. You have all your validation client-side using the common asp validation controls and validation summery...except...checking username availability, check emailadress availability, captcha and what not. So you end up with 2 kinds of validation and so presenting the user with 2 different UI's at 2 different moments. 2 words come to my mind. Ugly. Inconsistent. So here's the question. Why not do all the validation server-side (using AJAX or not). (I'm not using JQuery yet, should i?)

  • How test that ASP.NET MVC route redirects to other site?

    - by Matt Lacey
    Due to a prinitng error in some promotional material I have a site that is receiving a lot of requests which should be for one site arriving at another. i.e. The valid sites are http://site1.com/abc & http://site2.com/def but people are being told to go to http://site1.com/def. I have control over site1 but not site2. site1 contains logic for checking that the first part of the route is valid in an actionfilter, like this: public override void OnActionExecuting(ActionExecutingContext filterContext) { base.OnActionExecuting(filterContext); if ((!filterContext.ActionParameters.ContainsKey("id")) || (!manager.WhiteLabelExists(filterContext.ActionParameters["id"].ToString()))) { if (filterContext.ActionParameters["id"].ToString().ToLowerInvariant().Equals("def")) { filterContext.HttpContext.Response.Redirect("http://site2.com/def", true); } filterContext.Result = new ViewResult { ViewName = "NoWhiteLabel" }; filterContext.HttpContext.Response.Clear(); } } I'm not sure how to test the redirection to the other site though. I already have tests for redirecting to "NoWhiteLabel" using the MvcContrib Test Helpers, but these aren't able to handle (as far as I can see) this situation. How do I test the redirection to antoher site?

  • Can I perform some processing on the POST data before ASP.NET MVC UpdateModel happens?

    - by Domenic
    I would like to strip out non-numeric elements from the POST data before using UpdateModel to update the copy in the database. Is there a way to do this? // TODO: it appears I don't even use the parameter given at all, and all the magic // happens via UpdateModel and the "controller's current value provider"? [HttpPost] public ActionResult Index([Bind(Include="X1, X2")] Team model) // TODO: stupid magic strings { if (this.ModelState.IsValid) { TeamContainer context = new TeamContainer(); Team thisTeam = context.Teams.Single(t => t.TeamId == this.CurrentTeamId); // TODO HERE: apply StripWhitespace() to the data before using UpdateModel. // The data is currently somewhere in the "current value provider"? this.UpdateModel(thisTeam); context.SaveChanges(); this.RedirectToAction(c => c.Index()); } else { this.ModelState.AddModelError("", "Please enter two valid Xs."); } // If we got this far, something failed; redisplay the form. return this.View(model); } Sorry for the terseness, up all night working on this; hopefully my question is clear enough? Also sorry since this is kind of a newbie question that I might be able to get with a few hours of documentation-trawling, but I'm time-pressured... bleh.

  • Where and which data to save into session on an ASP.NET MVC 2 application?

    - by Shaharyar
    I am having some trouble saving the state of my current view. Currenly I have several selectlist calling their own Action method on the controller that returns the Index view with the filtered model based on the values of the selectlist. I have also written a little FileResult action that creates a csv file based on the current model. But I am only covering one selectlist right now as I only save the value of selectList1 into the session and access it with Session["SelectListValue1"] What are the best practices in this situation? Should I redo the entire (each action for each SelectList) part? Should I save each SelectLists value into the session and check if it's null? Or should I just save the Lambda Expression into the session and modify it during every call?
