• Can I have two separate projects, 1 WebForms and 1 ASP.NET MVC, to both point to the same domain?

  - by Hamman359

  Is it possible to setup two separate projects, 1 WebForms and 1 ASP.NET MVC, to both point to the same domain? i.e. both point to different pages within www.somesite.com. Here's some background on the application and why I'm asking. This is a brownfield application that is currently 2.0 WebForms and is full of WebFormy 'goodness' (i.e. ObjectDataSources, FormView controls, UpdatePanels, etc...) There are lost of other 'fun' things in the code base like 600+ Stored Procedures and 200+ line methods in the business layer code that get data from the DB via stored proc, do some processing on the data, build an HTML string using string concatenation and then return that string to the UI layer. What we are planning on doing is developing new features in MVC and slowly converting the existing features over to MVC one at a time. As part of this transition, we will also be re-writing the layers below the UI to clean up the mess there and to do things like replace the stored procedures with NHibernate and introduce an IOC container. I know that you can run WebForms and MVC side-by-side in the same project, however, because we will be making wholesale changes to the way we do many things throughout our entire development stack, I'd like the new stuff to be a completely separate project within the solution. This should help serve as very visual reminder that this is a different way of doing things than before and make it easier to remove the old code as it is no longer needed. What I don't know is, is this even possible? Can two separate project point to the same domain? Here's an quick example of what I'm thinking: www.somesite.com/orders.aspx?id=123 (Orders page from existing WebForms project) www.somesite.com/customer/987 (Customer page from new MVC project)

• ASP MVC: Custom Validation Attribute

  - by user323395

  I'm trying to write my own Custom Validation attribute but i'm having some problems. The attribute i'm trying to write is that when a user logs in, the password will be compared against the confirmation password. namespace EventCompanion.Data.Attributes { public class ComparePassword : ValidationAttribute { public string PasswordToCompareWith { get; set; } public override bool IsValid(object value) { if (PasswordToCompareWith == (string)value) { return true; } return false; } } Now my problem is when i'm trying to set the attribute like this in the model file: [Required] [ComparePassword(PasswordToCompareWith=ConfirmPassword)] public string Password { get; set; } [Required] public string ConfirmPassword { get; set; } } I get the following error: Error 1 An object reference is required for the non-static field, method, or property 'Project.Data.Models.GebruikerRegistreerModel.ConfirmPassword.get' It seems that VS is not accepting the confirmpassword in the "PasswordToCompareWith=ConfirmPassword" part Now my question: What am i doing wrong? Thanks in advance!!!

• ASP.Net MVC elegant UI and ModelBinder authorization

  - by SDReyes

  We know authorization stuff is a cross cutting concern, and we do anything we could to avoid merge business logic in our views. But I still not found an elegant way to filter UI components (e.g. widgets, form elements, tables, etc) using the current user roles without contaminate the view with business logic. same applies for model binding. Example Form: Product Creation Fields: Name Price Discount Roles: Role Administrator Is allowed to see and modify the Name field Is allowed to see and modify the Price field Is allowed to see and modify the Discount Role Administrator assistant Is allowed to see and modify the Name Is allowed to see and modify the Price Fields shown in each role are different, and model binding needs to ignore the discount field for 'Administrator assistant' role. How would you do it?

Controler function populating the jqgrid is something like this : Function GetGridRecordset(ByVal qry As String) As JsonResult Dim result = New JsonResult() ... ... Return result End Function Is there anyone who have a solution?

• ASP.NET MVC unit testing

  - by Simon Lomax

  Hi, I'm getting started with unit testing and trying to do some TDD. I've read a fair bit about the subject and written a few tests. I just want to know if the following is the right approach. I want to add the usual "contact us" facility on my web site. You know the thing, the user fills out a form with their email address, enters a brief message and hits a button to post the form back. The model binders do their stuff and my action method accepts the posted data as a model. The action method would then parse the model and use smtp to send an email to the web site administrator infoming him/her that somebody filled out the contact form on their site. Now for the question .... In order to test this, would I be right in creating an interface IDeliver that has a method Send(emailAddress, message) to accept the email address and message body. Implement the inteface in a concrete class and let that class deal with smtp stuff and actually send the mail. If I add the inteface as a parameter to my controller constructor I can then use DI and IoC to inject the concrete class into the controller. But when unit testing I can create a fake or mock version of my IDeliver and do assertions on that. The reason I ask is that I've seen other examples of people generating interfaces for SmtpClient and then mocking that. Is there really any need to go that far or am I not understanding this stuff?

• ASP.NET MVC: Routing

  - by JamesBrownIsDead

  Let's say I have this Controller: public class GlobalizationController : Controller { public JavaScriptResult GlobalizedLabels(string virtualPath) { return new JavaScriptResult(); } } I want the controller to handle (i.e. invoke from) any of the relative URLs below: /globalization/~Enlargement/Controls/Container.ascx /globalization/test/foobar.aspx /globalization/HappyTimes/Are/Right/Now What would my entry in global.asax routes.MapRoute() entry look like? As in... routes.MapRoute("Globalization", "globalization/{virtualPath}", new { controller = "Globalization", action = "GlobalizedLabels" }); The URL pattern "{virtualPath}" is wrong. What should it be?

• Preserve data in .net mvc

  - by Wei Ma

  I am implementing a search module with result page support paging. The example provided by NerdDinner passes pagenumber as a parameter for the Index action, and the action uses the pagenumber to perform a query each time the user hit a different page number. My problem is that my search take many more criteria such as price, material, model number etc. than just simple pagenumber. Therefore, I would like to preserve the criteria after users' first submission, so that I only have to pass the pagenumber back and forth. Using ViewData is not possible because ViewData get cleared once it is sent to the View. Is there any good way to preserve the criteria data as I wish?

• Asp.Net MVC best way to update cached table

  - by Eddy Mishiyev

  There are certain tables that get called often but updated rarely. One of these tables is Departments. So to save DB trips, I think it is ok to cache this table taking into consideration that the table has very small size. However, once you cached it an issue of keeping the table data fresh occurs. So what is the best way to determine that the table is dirty and therefore requires a reload and how that code should be invoked. I look for solution that will be scalable. So updating the cache right after inserting will not work. So if one machine inserted the record all other on network should get notified to reload the cache. I was thinking for calling corresponding web service from T-SQL but don't really like the idea of consuming recourses on sql server. So what are the best practices to resolve this type of problems. Thanks in advance Eddy

• HttpRequestValidationexception on Asp.Net MVC

  - by elranu

  I’m getting an HttpRequestValidationexception with this error message: “A potentially dangerous Request.Form value was detected from the client”. But I have AllowHtml on the property that I’m getting the error. The problem is that later in my code I’m getting the following property to know in witch format I will show my view ControllerContext.HttpContext.Request.Params.AllKeys.Contains("format"). And on this “Param Getter” I’m getting the error. Let’s say my code is similar to the following: public class House { [AllowHtml] public string Text { get; set; } public string Name { get; set; } } [HttpPost, ValidateAntiForgeryToken] public ActionResult CreateTopic(House h) { //business code if(ControllerContext.HttpContext.Request.Params.AllKeys.Contains("format")) { Return view; } } How can I solve this? I already try with the ValidateInput(false) attribute on the controller action method. Any idea?

• C#/ASP.NET MVC 4 Instantiate Object Derived From Interface In Factory Method

  - by Chris

  Currently have a Factory class that features a GetSelector function, which returns a concrete implementation of ISelector. I have several different classes that implement ISelector and based on a setting I would like to receive the appropriate ISelector back. public interface ISelector { string GetValue(string Params); } public class XmlSelector : ISelector { public string GetValue(string Params) { // open XML file and get value } } public static class SelectorFactory { public static ISelector GetSelector() { return new XmlSelector(); // Needs changing to look at settings } } My question is what is the best way to store the setting? I am aware of using AppSettings etc. but I'm not sure whether I want to have to store strings in the web.config and perform a switch on it - just seems to be really tightly coupled in that if a new implementation of ISelector is made, then the Factory would need to be changed. Is there any way of perhaps storing an assembly name and instantiating based on that? Thanks, Chris

I've done a lot of reading into the various patterns suggested for development, somthing that has split the team at the moment is when using Entity Framework should the classes be passed through the applciation layers so that a view accepts an Entity Framework class or should these classes be mapped to BLL Classes and if so at which point (Controller or Library) should this be done? I'm interested in hearing some positives and negitives for each solutions.

• Problem Paging with Post Action in ASP.NET MVC

  - by Lukasz

  I have a page that takes a number of parameters on a form and posts them to an action. It returns a number of search results that need to be paged through. My pager uses ActionLink; <%= Html.ActionLink(i.ToString(), "Basic", new { page = (i - 1) })%> The results comeback as expected but when I click on page two it goes to the default Action, not the one marked with post. The form values do no get submitted again and the results that are shown for page two are the default results not filters with the parameters. I am not sure how to solve this problem? One way was to save the form values into the database on the post and reading them back on the default action but it seems overkill. Thank You!

• Problem with ASP.NET MVC DropDownList not displaying selected value

  - by Jova

  I have an aspx page which allows me to edit articles. Among things I can edit is which category the article belongs to. The category is chosen through a DropDownList as shown here, <%= Html.DropDownList("categoryID", (IEnumerable<SelectListItem>)ViewData["CategoryID"], new { @class = "textbox" }) %> However, the articles category isn't selected when I go to that page. The ViewData I use for the DropDownList looks like this, ViewData["CategoryID"] = new SelectList(categories, "CategoryID", "Title", article.CategoryID); Which should select the article.CategoryID as it's selected value. Have I done this wrong?

• Passing data from a View to a controller in ASP.Net MVC

  - by kingrichard2005

  Hello, I have a dictionary I'm passing to a View. I want to be able to pass the values of that dictionary back to a Controller action from this same View. Is there anyway this can be accomplished without using a form? The situation is that I need to be able to pass these back to a controller action that is called when a user clicks an ActionLink from the View, and in my experience an ActionLink cannot be used to submit a values of a form, i.e. I've only been able to submit values of a form using the form's submit button. Unless there's a way to use an ActionLink to submit values in a form.

• MVC Partial View Not Refreshing when using JSON data

  - by 40-Love

  I have a dropdown that I'm using to refresh a div with checkboxes. I am trying to figure out why my view is not refreshing if I pass in data in JSON format. If I pass in just a regular string, the view refreshes. If I pass in JSON data, the view does not refresh. If I step through the code in the Partial view, I can see the correct number of records are being passed in, however the view doesn't get refreshed with the correct number of checkboxes. I tried to add some cache directives, it didn't work. This doesn't work: $(function () { $('#ddlMoveToListNames').change(function () { var item = $(this).val(); var selectedListID = $('#ddlListNames').val(); var checkValues = $('input[name=c]:checked').map(function () { return $(this).val(); }).toArray(); $.ajax({ url: '@Url.Action("Test1", "WordList")', type: 'POST', cache: false, data: JSON.stringify({ words: checkValues, moveToListID: item, selectedListID: selectedListID }), dataType: 'json', contentType: 'application/json; charset=utf-8', success: function (result) { } }) .done(function (partialViewResult) { $("#divCheckBoxes").replaceWith(partialViewResult); }); }); }); This works: $(function () { $('#ddlMoveToListNames').change(function () { var item = $(this).val(); var selectedListID = $('#ddlListNames').val(); var checkValues = $('input[name=c]:checked').map(function () { return $(this).val(); }).toArray(); $.ajax({ url: '@Url.Action("Test1", "WordList")', type: 'POST', cache: false, data: { selectedListID: item }, success: function (result) { } }) .done(function (partialViewResult) { $("#divCheckBoxes").replaceWith(partialViewResult); }); }); }); Partial View: @model WLWeb.Models.MyModel <div id="divCheckBoxes"> @foreach (var item in Model.vwWordList) { @Html.Raw("<label><input type='checkbox' value='" + @Html.DisplayFor(modelItem => item.Word) + "' name='c'> " + @Html.DisplayFor(modelItem => item.Word) + "</label>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"); } </div> Controller: [AcceptVerbs(HttpVerbs.Post)] [OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")] public PartialViewResult Test1(MyModel vm, string[] words, string moveToListID, string selectedListID) { int listNameID = Convert.ToInt32(moveToListID); List<vwWordList> lst = db.vwWordLists.Where(s => s.Word.StartsWith("wa") && s.ListID == listNameID).ToList(); vm.vwWordList = lst; return PartialView("Partial1", vm); } View: @Html.DropDownListFor(x => Model.FilterViewModel.MoveToListNameID, Model.FilterViewModel.MoveToListNameList, new { @id = "ddlMoveToListNames", style = "width:100px;" })
