  • ASP.NET MVC2 : DateTime modelbinding via HTTP GET

    - by mathieu
    I'm getting some trouble binding a date from QueryString : I have the following model public class QueryParms { public DateTime Date { get; set; } } And the following controller action : public ActionResult Search( QueryParms query ); I have a form, with a field where I can type my date. If the form is FormMethod.Post, everything is fine, my date is correctly bound to my model. If the form is FormMethod.Get, it is not working anymore. The date is left to the default value (01/01/0001) I think it is a culture issue : When i look into the value provider, the FormValueProvider has a culture property set for my date : {fr-FR}. The QueryStringValueProvider doesn't have the culture property set. Is there a way to set this property ?

  • How to separate model and view with Core Data?

    - by andrewebling
    I have a subclass of UIView which draws itself based on data held in a corresponding model class, which is a subclass of NSManagedObject. The problem is, some fields in the data model (e.g. the position of the view) are already held in the view (i.e. the frame property in this case). I then have a data duplication/synchronization problem to solve. To complicate matters further, the view needs to update in response to changes made to the data model and the data model needs to be updated in responses made to the view (e.g. the user dragging it to a new location). What's the best way to solve this? Using KVO and references in both directions? Or is there a better approach?

    - by Ian Boyd
    If from one view a user enters some invalid data, e.g.:     E-mail: [email protected]     then i want the controller to: not place the data into the model color the text box reddish not allow the user to save But it's possible that if the user enters the same invalid data in a different view i want the controller to: place the data into the model color the text box reddish allow the user to save But it's possible that if the user enters the same invalid data in a different view i want the controller to: place the data into the model color the text box bluish allow the user to save And it's possible that another view will: place the data into the model leave the text box uncolored allow the user to save And it's possible that another view will: auto-correct the data, placing it into the model color the text-box reddish allow the user to have And it's possible for another view to: auto-correct the data, placing it into the model update the view with the new data color the text-box bluish allow the user to save [ad infinitum] Without using n-controllers for n-views, how do i do this?

  • Cannot see index view of my controller - routing related

    - by olst
    Hi. I have a controller named Content, which has an Index action, which is associated with a view. I would like the simple route "content" to show me the index view of the content controller, so I use the following code (with the addition of the default site home route): routes.MapRoute( "ContentIndex", "content", new { controller = "Content", action = "Index"} ); routes.MapRoute( "Default", "{controller}/{action}", new { controller = "Home", action = "Index" } ); when I type the url : "http://localhost/content/", I get an error 404 saying the resource cannot be found, but when I type "http://localhost/content/index", it shows the content index view. How can I get rid of the index in the url ? Thanks !

  • Using AJAX to return SelectList selected value

    - by Adventure
    At risk of asking the obvious... I need to use AJax.ActionLink to send the current value of a SelectList back to my controller. How do I do that? Below is part of my current View. I need to replace "15" with the current value of the SelectList. <% If Model.ShoppingListNames IsNot Nothing Then%> <%: Html.DropDownList("ShoppingListNames", Model.ShoppingListNames)%> <%: Ajax.ActionLink("Add to List", "AdjustMaterials", "Docs", New With {.userDocId = 15, .prodId = Model.ID, .quantity = 1}, New AjaxOptions With {.OnSuccess = "handleUpdate"})%> <% End If%>

  • error while adding WCF service reference

    - by user1561256
    There was an error downloading . Unable to connect to the remote server No connection could be made because the target machine actively refused it Metadata contains a reference that cannot be resolved.There was no endpoint listening at that could accept the message. This is often caused by an incorrect address or SOAP action. See Inner Exception, if present, for more details. Unable to connect to the remote server No connection could be made because the target machine actively refused it. If the service is defined in the current solution, try building the solution and adding the service reference again. can pls somebody solve this.

  • What is the best way to store static data in C# that will never change

    - by Luke101
    I have a class that stores data in asp.net c# application that never changes. I really don't want to put this data in the database - I would like it to stay in the application. Here is my way to store data in the application: public class PostVoteTypeFunctions { private List<PostVoteType> postVotes = new List<PostVoteType>(); public PostVoteTypeFunctions() { PostVoteType upvote = new PostVoteType(); upvote.ID = 0; upvote.Name = "UpVote"; upvote.PointValue = PostVotePointValue.UpVote; postVotes.Add(upvote); PostVoteType downvote = new PostVoteType(); downvote.ID = 1; downvote.Name = "DownVote"; downvote.PointValue = PostVotePointValue.DownVote; postVotes.Add(downvote); PostVoteType selectanswer = new PostVoteType(); selectanswer.ID = 2; selectanswer.Name = "SelectAnswer"; selectanswer.PointValue = PostVotePointValue.SelectAnswer; postVotes.Add(selectanswer); PostVoteType favorite = new PostVoteType(); favorite.ID = 3; favorite.Name = "Favorite"; favorite.PointValue = PostVotePointValue.Favorite; postVotes.Add(favorite); PostVoteType offensive = new PostVoteType(); offensive.ID = 4; offensive.Name = "Offensive"; offensive.PointValue = PostVotePointValue.Offensive; postVotes.Add(offensive); PostVoteType spam = new PostVoteType(); spam.ID = 0; spam.Name = "Spam"; spam.PointValue = PostVotePointValue.Spam; postVotes.Add(spam); } } When the constructor is called the code above is ran. I have some functions that can query the data above too. But is this the best way to store information in asp.net? if not what would you recommend?

  • Where do you put non-controller classes in codeigniter?

    - by sprugman
    I've got a class Widgets. Widgets are made up of Doohickies. I'm never going to need to access Doohickies directly via url -- they're essentially a private class, only used by Widgets. Where do you put your code to define the Doohicky class? In /app/controllers/doohicky.php? in app/controllers/widget.php? somewhere else? Obviously, the former seems cleaner, but it's not obvious to me how to make the Doohicky class available to Widget.

  • How to send link/url to confirm user registration and/or password reset/recovery using ASP.Net MVC2?

    - by Mark_DVM_Software
    Hi, I see it all over the place, yet, I could not find one example about this (maybe I don't know the proper wording), I am trying to build using ASP .Net MVC2 (but any example on just ASP .Net would be also helpful) a process that will send a link to the user at the end of the registration process to let him confirm his registration. Also, a similar process to let the user to reset his password, with the typical "forgot password" and send a link/url so that the user can click and type a new password. Can someone help me to either find an example or at least to let me know how to "google" it? Thanks, Mark

  • Render different view depending on the type of the data

    - by Miau
    Hi there So lets suppose we have an action in a controller that looks a bit like this: public ViewResult SomeAction(int id) { var data = _someService.GetData(id); ... //create new view model based on the data here return View(viewModel); } What I m trying to figure out is the best way to render a diferent view based on the type fo the data. the "_someService.GetData method returns an data that knows its out type (ie not only you can do typeof(data) but also you can do data.DataType and you ll get an enum value so I could achieve what I m trying to do doing something kinda like this public ViewResult SomeAction(int id) { var data = _someService.GetData(id); //I m mapping fields to the viewModel here var viewModel = GetViewModel(data); swtich(data.DataType) case DataType.TypeOne: return View("TypeOne", viewModel); break; ... } But this does not seem to be the nicest way, (I dont event know if it would work) Is this the way to go? Should I use some sort of RenderPartial Aproach? after all , waht will change in the view is mostly the order of the data (ie the rest of the view would be quite similar) Cheers

  • LINQ query for tag system: Matching any of several tags?

    - by David Veeneman
    I am just getting started with LINQ. I am creating an Entity Framework app that uses the canonical Post and Tag model. A Post contains an ID, Text, and Tags, and a Tag contains an ID, a Name, and Posts. A previous thread on StackOverflow showed me how to query for a Post that matches all Tag objects (A and B and C) in a search list. But how would I query for a Post that matches any Tag (A or B or C) in the list? Thanks for your help.

  • How with lambda function in MVC3

    - by doogdeb
    I have a model which contains view models for each view. This model is held in session and is initialised when application starts. I need to be able to populate a field from one view model with the value from another so have used a lambda function. Below is my model. I am using a lambda so that when I get Test2.MyProperty it will use the FunctionTestProperty to retrieve the value from Test1.TestProperty. public class Model { public Model() { Test1 = new Test1() Test2 = new Test2(FunctionTestProperty () => Test1.TestProperty) } } public class Test1 { public string TestProperty { get; set; } } public class Test2 { public Test2() : this (() => string.Empty) {} public Test2(Func<string> functionTestProperty) { FunctionTestProperty = functionTestProperty; } public Func<string> FunctionTestProperty { get; set; } public string MyProperty { get{ return FunctionTestProperty() ?? string.Empty; } } } This works perfectly when I first run the application and navigate from Test1 to Test2; I can see that when I get the value for MyProperty it calls back to Model constructor and retrieves the Test1.TestProperty value. However when I then submit the form (Test2) it calls the default constructor which sets it to string.Empty. So if I go back to Test1 and back to Test2 again it always then calls the Test2 default constructor. Does anyone know why this works when first running the application but not after the view is submitted, or if I have made an obvious mistake?

  • Dictionary to Json object, "Expected expression"

    I'm trying to convert a dictionery into a json object, so that I can work with it in my front end. sortFields = <%= SchrodersHtmlHelper.ToJson(ViewData["SortInfo"])%>; However, I keep on getting "Expected expression" for this all the time and I'm clueless why. Could anyone explain to me what I'm doing wrong? Edit: The conversion works fine, but I still get this issue in the front end, causing the browser to complain about it.

  • Call an action from another controller

    - by Brian
    I have two different objects: contracts, and task orders. My requirements specify that in order to view the Details for either object, the Url should be "http://.../Contract/Details" or "http://.../TaskOrder/Details" depending on which type. They are both very similar and the details pages are almost identical, so I made a class that can either be a contract or a task order, and has a variable "objectTypeID" that says which type it is. I wrote the action "Details" in the task order controller, but now I want to call that from the contract controller instead of recopying the code. So is there any way to have the url still say ".../Contract/Details" but call the action in the TaskOrder controller instead? I tried using TaskOrderController TOController = new TaskOrderController(); TOController.Details(id); This would have worked except that I can't use the HttpContext.Session anymore, which I used several times in the action.

  • EF Stored Procedure Complex Type

    I am using EF4. I am somewhat confused on on the Entity Framework Complex name. When I go to Functional Import of a Stored Procedure name and it ask me to type in the Complex name, is that supposed to be the name of of a class that can handle that output. For examle, say if my stored procedure returns FirstName, LastName. Is the Complex name supposed to be a class that can handle that output in this case PersonName? public class PersonName { public string FirstName {get; set;} public string LastName {get;set} }

    I'm using : $(window).scroll(function () { if ($(window).scrollTop() + 10 >= ($(document).height() - $(window).height())) { loadContent(); } } It works fine with Chrome, IE, Firefox but except in Safari.
