  • How can I use a prefix for the fields in my strongly typed View?

    - by deadtime
    Hi, I have an EditProfile action in my PersonController, that finds a Person object by ID and does return View(person). The EditProfile view has a bunch of fields that should be filled in with the information from the Person object. One of the fields is named "Person.FirstName", and is not filled in automatically when the View is rendered. However, if I rename the textbox to "FirstName", it gets filled in. My question is: How can I specify to the view that it should use the "Person" prefix when filling in the information from the Person object? The reason I want to do this is because of consistency - in some of my views I allow the user to edit more than one object at the same time, and use prefixes in order to bind these correctly.

  • Spring Framework HttpRequestHandler failure

    - by sharadva
    We have an application which communicates via REST requests made by clients. The REST requests contain "region name" and a "ID" as parameters So, a request would look something like this (for a DELETE) http://host:port/regionnameID These REST requests between regions in a federation are properly URL encoded I find that these request fail if the region name has a slash ("/") in it. Then, the request would look like so http://host:port/region/nameID This is due to incorrect interpretation of the Rest URL by HttpRequesthandler when there is a '/' in the region name. Now, we have no control over clients sending REST request with "/" in the Region name. Is there any method / configuration / workaround that can be done to prevent the HttpRequestHandler from returning 404

  • FluentNHibernate: multiple one-to-many relationships between the same entities.

    - by Venemo
    Hi, I'm working on a bug tracking application. There are tickets, and each ticket has an opener user and an assigned user. So, basically, I have two entities, which have two many-to-one relationships with each other. Their schematic is this: User: public class User { public virtual int Id { get; private set; } ... public virtual IList<Ticket> OpenedTickets { get; set; } public virtual IList<Ticket> AssignedTickets { get; set; } } Ticket: public class Ticket { public virtual int Id { get; protected set; } ... [Required] public virtual User OpenerUser { get; set; } public virtual User AssignedUser { get; set; } } I use FluentNHibernate's auto mapping feature. The problem is, that no matter whether relationship I set, on the side of the User, both collections always contain the same data. I guess Fluent can't tell which end of which relationship belongs to where. I googled around but haven't found anything useful. Could anyone help me, please?

  • Detect whether or not a specific attribute was valid on the model

    - by Sir Code-A-Lot
    Having created my own validation attribute deriving from System.ComponentModel.DataAnnotations.ValidationAttribute, I wish to be able to detect from my controller, whether or not that specific attribute was valid on the model. My setup: public class MyModel { [Required] [CustomValidation] [SomeOtherValidation] public string SomeProperty { get; set; } } public class CustomValidationAttribute : ValidationAttribute { public override bool IsValid(object value) { // Custom validation logic here } } Now, how do I detect from the controller whether validation of CustomValidationAttribute succeeded or not? I have been looking at the Exception property of ModelError in the ModelState, but I have no way of adding a custom exception to it from my CustomValidationAttribute. Right now I have resorted to checking for a specific error message in the ModelState: public ActionResult PostModel(MyModel model) { if(ModelState.Where(i => i.Value.Errors.Where((e => e.ErrorMessage == CustomValidationAttribute.SharedMessage)).Any()).Any()) DoSomeCustomStuff(); // The rest of the action here } And changed my CustomValidationAttribute to: public class CustomValidationAttribute : ValidationAttribute { public static string SharedMessage = "CustomValidationAttribute error"; public override bool IsValid(object value) { ErrorMessage = SharedMessage; // Custom validation logic here } } I don't like relying on string matching, and this way the ErrorMessage property is kind of misused. What are my options?

  • Creating seed model from data already in DB

    - by Nick Brown
    Is there a way to convert data in an existing database into objects that can easily be put into a seed method? Essentially I'd like to let some people add lines to my DB via a form and then convert that into an object that I can re-seed the DB anytime I need to make changes. The database itself is created via code-first using the following model: public class Combo { public int Id { get; set; } public string MainPrefix { get; set; } public string MainDescriptor { get; set; } public string MainDish { get; set; } public string Connector { get; set; } public string SecondaryDescriptor { get; set; } public string SecondaryDish { get; set; } }

  • using partials in view helpers

    - by takeshin
    Creating custom Zend View helpers I often end up with something like: // logic here if ($condition) { $output = <<<EOS... } else { $output = <<<EOS... } or using switch. Then to eliminate this, I create setPartial(), getPartial() and htmlize() for using external .phtml's. This is not the best solution, because partials do not support doctype changing. Is there any better solution, than creating abstract class handling this common case? Are there any ready Zend solutions for this case? Separate view helper for each case? And where to put common code?

  • How to limit select items with L2E/S?

    - by orlon
    This code is a no-go var errors = (from error in db.ELMAH_Error select new { error.Application, error.Host, error.Type, error.Source, error.Message, error.User, error.StatusCode, error.TimeUtc }).ToList(); return View(errors); as it results in a 'requires a model of type IEnumerable' error. The following code of course works fine, but selects all the columns, some of which I'm simply not interested in: var errors = (from error in db.ELMAH_Error select error).ToList(); return View(errors); I'm brand spanking new to MVC2 + L2E, so maybe I'm just not thinking in the right mindset yet, but this seems counter-intuitive. Is there an easy way to select a limited number of columns, or is this just part of using an ORM?

  • Passing Object From Controller to JavaScript JQuery

    - by TMan
    This is driving me crazy. All I'm trying to do is to pass in a Id to a ActionMethod which is working and have an Object be returned to the javascript. Then in javascript, I want to be able to say something like..Objec.Property, ie/ Student.Name, or Student.GPA. Any help is appreciated. I tried json but couldn't get that to work either. ActionResult: [AcceptVerbs(HttpVerbs.Get)] public Epic GetEpicPropertyDetails(int id) { var Epictemplist = epicRepository.Select().Where(x => x.Id.Equals(id)); return Epictemplist.SingleOrDefault(); } javascript: <script type="text/javascript"> $(document).ready(function () { $(".ListBoxClass").click(function (event) { var selectedid = $(this).find("option:selected").val(); event.preventDefault(); $.get("/Estimate/GetEpicPropertyDetails", { id: selectedid }, function (result) { $(".TimeClass").val(result); }); }); }); </script> result.Name is obviously wrong I just dont know how to call this the right way.

  • How to check if an entityset is populated

    - by TheQ
    How can i check if an entityset of a linq-object is populated or not? Example code below. My model have two methods, one joins data, and the other does not: public static Member GetMemberWithSettings(Guid memberId) { using (DataContext db = new DataContext()) { DataLoadOptions dataLoadOptions = new DataLoadOptions(); dataLoadOptions.LoadWith<Member>(x => x.Settings); db.LoadOptions = dataLoadOptions; var query = from x in db.Members where x.MemberId == memberId select x; return query.FirstOrDefault(); } } public static Member GetMember(Guid memberId) { using (DataContext db = new DataContext()) { var query = from x in db.Members where x.MemberId == memberId select x; return query.FirstOrDefault(); } } Then my control have the following code: Member member1 = Member.GetMemberWithSettings(memberId); Member member2 = Member.GetMember(memberId); Debug.WriteLine(member1.Settings.Count); Debug.WriteLine(member2.Settings.Count); The last line will generate a "Cannot access a disposed object" exception. I know that i can get rid of that exception just by not disposing the datacontext, but then the last line will generate a new query to the database, and i don't want that. What i would like is something like: Debug.WriteLine((member1.Settings.IsPopulated()) ? member1.Settings.Count : -1); Debug.WriteLine((member2.Settings.IsPopulated()) ? member2.Settings.Count : -1); Is it possible?

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

    - 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?

  • Does anyone know why jquery dialog is showing stale content on ajax update ?

    - by oo
    I have a series of links and when i click on a link i want to show a dialog with detail information. This detail is returned from an jquery ajax request. I am using the following code below to show a partial result through ajax onto a jquery dialog. Here is the jquery code: $(document).ready(function() { $('a.click').live('click', function() { var url = '/Tracker/Info?id=' + $(this).attr("id"); var dialogOpts = { modal: true, bgiframe: true, autoOpen: false, height: 600, width: 450, overlay: { opacity: 0.7, background: "black" }, draggable: true, resizeable: true, open: function() { //display correct dialog content $("#dialogDiv").load(url); } }; $("#dialogDiv").dialog(dialogOpts); //end dialog $("#dialogDiv").dialog("open"); }); }); Here is my controller action code: public ActionResult Info(int id) { return PartialView("LabelPartialView", _Repository.GetItem(id)); } Here is the issue: When i click this the first time (lets say i send id = 1234) it works fine. When i click on another item (lets say i send id = 4567) it shows the content from 1234 still. Which i click this second item again (again its 4567), then it will show the content from 4567. Does anyone know why it might not be refreshed the first time? Is this a timing issue?

I don´t know which tutorial from that I found is best for me.

  • Navigating by foreign keys in ADO.NET Entity Framework/MySQL

    - by Werg38
    I am using ASP.NET MVC2 on top of a MySQL database in VS2008. I am using the MySQL ADO.NET connector 6.2.3 to provide the connection for the ADO.NET Entity Data Model. This is mostly working ok, however navigating via foreign keys is causing me a real headache! Here is a simplified example.. Car (Table) CarID PK Colour Doors ManufacturerID FK Manufacturer (Table) ManufacturerID PK Name In the edmx file I can see the 1-many relationship shown as a navigation property in the both the Car and Manufacturer tables. I create a Models.CarRepository that allows me to returns a IQueryable. At the View I want to be able to display the Manufacturer.Name for each car. This is not accessible via the object I get returned. What is best way to implement this? Have I encountered a limitation of the Entity Framework/MySQL combination?
