If I pass in true to the ValidationSummary() helper so that it only displays model-level errors, how can I get the summary to display custom errors I add to ModelState?For instance, here is what I am after. I want my data annotation errors to display next to the textbox's using the ValidationMessage helper, but in my business layer I may throw an exception that I want to display in the validation summary.

I want to capture errors on a per-page level. I've added the following code to my code behind page:
public void Page_Error(object sender, EventArgs e)
{
Response.Write("Unhandled error on the page.");
}
I have also ensures that AutoEventWireup="true".
I have some gridviews on this webpage that use a SQLDataSource. I'm hoping to use this error message (which will be better when I get it working, response.write is mostly just to test) to cover up those errors with something more user friendly. Yet when I have an error ("Cannot open database" for instance), Page_Error never fires and I get the ugly yellow screen of death instead.
When setting up asp.net error handlers for things like 404 errors, it is more 'efficient' to do this in IIS, or handle it in the Global.asax Application_Error event? I know the latter will be called, and I want to log this information in a database, but should I then just return without any redirect and let IIS do the redirect, or would it be better to do a response.redirect inside application_error once we've logged it?

The first time I created my model, I thought a manual fix would keep it okay. But everytime I open my project, the model is updated and the Designer.cs is formatted weird. The following picture shows the main problem: I'm just not sure how to permanently fix it other than going through and deleting the "System.Data." and "System.whatever" paths when they are referenced. That is the only way the build/publish succeeds, and it's very time consuming to complete each time.
View 3 RepliesSuppose i have an insert function in my model like so:

I've got a multi level dependency chain in my object model: An organization has the following children relationships:
Organization
.CompetitionGroups
.CompetitionGroups.Venues
.CompetitionGroups.Competitions
.Divisions.Games
.Divisions.Games.Participants
.Divisions.Games.Participants.GameSegments
.Divisions.SubDivisions...
.Divisions
.Teams
.Teams.Players
.Teams.Participants
.Teams.Participants.GameSegments
.VenueDates
This is just a glimpse at the object model, but it's focused on the complexity of the relationships and lists. What I can't really get is what's the best way to factor my repository interfaces, given the requirements to do a unit of work. For example, to create a game, you'll need a venuedate and two participants. Does that mean the GamesController should require an IGameRepository, an IVenueDateRepository, and an IParticipant repository? Should they be rolled into one repository?
Also, what about in the consumption cases? For example, to display a signle team's schedule, you'll need all of the Participants for that Team, all of the Games for that participant, and all of the GameSegments for the participant. If those are factored into individual repositories I can't see how you can do efficient queries. Does that mean you have Repositories specifically focused on different cases? for example:
public interface IScheduleRepository {
public ICollection<Game> GetScheduleForTeam(Team team);
// More consumption methods
}
public class ScheduleRepositry : IScheduleRepository {
public ScheduleRepository (ModelContext context) {
// Do stuff with context
}
public ICollection<Game> GetScheduleForTeam(Team team) {
return (
from p in context.Participants
where ((p.Game.VenueDate != null) &&
(p.TeamId == team.Id))
orderby p.Game.VenueDate.StartTime
select p.Game).ToList();
}
// more consumption methods
}
public interface IGameRepository {
public void AddGame(Game game);
// More crud methods
}
// Not showing games repository
public class GamesController : Controller {
public GamesController (IGameRepository gamesRepo,
IVenueDateRepository venueDateRepo,
IParticipantRepository participantRepo) {
// do stuff with repos here
}
[HttpPost]
public ActionResult AddGame(Game game) {
// Skipping validation logic
// this?
VenueDate = venueDateRepo.Add(game.VenueDate);
foreach (Participant p in Game.Participants)
{
participantRepo.Add(p);
}
Game = gamesRepo.AddGame(game);
// or this?
// how would the game repo know to persist
// the children elements? is that tight coupling?
Game = gamesRepo.AddGame(game);
}
// more consumption methods
}
My question is I don't yet understand to what degree factoring your repositories make sense based on a connected object model. I'd love to get some advice here.
I am a MVC newbie & am lost in various ways validation can be implemented in my application.
I created a custom model-level data annotation validator attribute, but am unable to display its error message in the view. Basically, I have let's say 5 properties in the Entity class Job (model-level custom attribute called UniqueKeywords defined on it):
1) LoginID: value comes in the URL
2) Title: Required property level attribute defined on it
3) CatID1, CatID2, CatID3 - 3 categoryIDs - these are dropdowns in the view with same list of keywords in all 3.
I want to mandate that the values picked by the user in all 3 category dropdowns should be different.
With reference to the code pasted below, here is the explanation of what happens:
When I submit the form without specifying a title or picking anything from any of the 3 category dropdowns, the validation occurs for the property level Required attribute as well as model level uniquekeywords attribute, but the error is displayed only next to the required field "Title". I can confirm that the custom validation also works by filling in some text in the Title field & then re-posting the form...this re-displays the view, but the error message "Category cannot be duplicated" is not displayed.
Only relevant code sections are pasted below:
My Entity class code:

I'm wondering what the best practice is in reporting back to the browser about application or model state errors that would be displayed to the user. Can you throw an exception and handle it in the error handler of the jquery post? For example, consider this method:
[HandlerErrorWithAjaxFilter, HttpPost]
public ActionResult RetrievePassword(string email)
{
User user = _userRepository.GetByEmail(email);
if (user == null)
throw new ClientException("The email you entered does not exist in our system. Please enter the email address you used to sign up.");
string randomString = SecurityHelper.GenerateRandomString();
user.Password = SecurityHelper.GetMD5Bytes(randomString);
_userRepository.Save();
EmailHelper.SendPasswordByEmail(randomString);
if (Request.IsAjaxRequest())
return Json(new JsonAuth { Success = true, Message = "Your password was reset successfully. We've emailed you your new password.", ReturnUrl = "/Home/" });
else
return View();
}
Is it correct to throw an exception in this case when the user is null? Or should I instead do this and handle it in the success handler of the jquery post: return Json(new JsonAuth { Success = false, Message = "The email you entered does not exist in our system. Please enter the email address you used to sign up.", ReturnUrl = "/Home/" });
Curious what the best practice is for returning errors to a view from a controller where the error isn't really a validation error, but more like "user not found" or "service timeout" type of errors. (in ASP.NET MVC2 framework)
I've been adding them to the ModelState's model errors, but that doesn't seem appropriate. (although easy to implement and maintain)
Example - A user tries to log in, and their credentials do not match a known user.
I have to handle error related to web application. I am not sure how its works. I am thinking that I will add an error page (error.aspx) and in global.asax ,application_onError, I will redirecting the user to error page and that should be enough ! i mean it will handle error automatically.

This would be a minor inconvenience except that by the fact it falls back to IIS native instead of my application it completely circumvents Elmah logging my 404 exceptions correctly.

I'm building an MVC 2 RTM app, and I want to be able to share my model across applications. I'd *like* to be able to implement it like:ASP.NET MVC2 app (holds Views and Controllers)Class library to hold Model(s)WCF app to handle the data transactions with the models via different data stores across apps I had the MVC app working fine, but I wanted to abstract the data stuff and be able to work with the model across apps through the WCF site, so I created a class library project and moved all of the Models classes into that and set-up a WCF app, then added project references to the MVC and WCF apps that point at the class library. The idea was I can create services that take and return objects from the model via method calls across apps. It appears that everything's wired up correctly in the MVC project, so I'm passing the objects stored in the Models class library between controllers and views and everythig is compiling just fine, but for some reason the data is not being passed back from the views to the controller on POST -- all of the properties in the classes are null or empty.
When I debug the app, I can see that the values are stored in the model data dictionary but not the model object itself. What am I doing wrong? Am I on the wrong path, or missing something obvious (to some)?
Is it possible, inside a Custom Model Binder, to fire "something" that "says" the value is invalid so it gets handled by validation part?
Basically, I am getting an exception when the value for the property is invalid.
I made a few changes to the DB in SQL server management studio then right clicked on the .edmx doc to get it to update. That seemed to work fine but when i compiled the app everything that referenced the EF seems to be broken.The Error list now contains the below error for all classes that used it.
The type or namespace name '' could not be found (are you missing a using directive or an assembly reference?)
I have an issue of static variable in an asp.net application. Let's say I have a server with 8 CPUs running windows 2008 R2 hosting an asp.net webbsite, nothing fancy here, no funny configuration.
Is the following statement true? at any single time, there's one and only one process is running and accepting requests, even in the recycling stage. The reason I am asking is: I have a static field in my class, and I want to make that's the only static instance in the website. I've heard in some circumstances, IIS is recylcing your application, and it will start a new process, but the old process is still working, thus I will have 2 static instances in memory, which defeat the purpose of static field.
One step further, let's assume there might be 2 instances in memory, can I assume there are at most 2 instances at any single time? And can I assume once the second instance is up, the first instance will NEVER accept new requests?
Another question: Recently I have a problem with an applicationdomain concept. Looks like if an application domain causes a memory leak, unload the domain will not release the memory (Umanaged leak). So to what extent Application Domain is isolated?
I am new to ASP.NET so may be my question sounds stupid but here is it anyway: Why a postback happens when we use aValidationSummary control? When I am using RequiredFieldValidator control then postback is not happening if the validation fails which is right. But if I useValidationSummary control then postback starts happening even if the validation should fail.
I have 2 text boxes txtUserName and txtPassword and a button btnLogin on my page. I have a RequiredFieldValidator control for each text box. If any of the text box is empty and I click the Login button, the postback does not happen and I got error message(s) which is good.
[Code]....
Now I add a ValidationSummary control. Now if any of the text box is empty and I click the Ok button, the postback happens which is bad.

I am trying to make a post that should use the Default Model Binder functionality in ASP.NET MVC 2 but unfortunately I can't get through. When I click on the checkout button I populate a form dinamically using jQuery code and then submit this form to the server. This is the form that get submitted
<form action="/x/Order/Checkout" id="cartForm" method="post">
<input name="__RequestVerificationToken" type="hidden" value="UDjN9RdWheKyWK5Q71MvXAbbDNel6buJd5Pamp/jx39InuyYIQVptcEubIA2W8DMUzWwnZjSGkLspkmDPbsIxy8EVuLvfCSZJJnl/NrooreouptwM/PaBEz2v6ZjO3I26IKRGZPqLxGGfITYqlf8Ow==">
<input id="CustomerID" name="CustomerID" type="hidden" value="1">
<input id="FirmID" name="FirmID" type="hidden" value="2">
<input type="hidden" name="CartItems[0].ServiceTypeID" value="1">
<input type="hidden" name="CartItems[0].Quantity" value="1">
<input type="hidden" name="CartItems[1].ServiceTypeID" value="2">
<input type="hidden" name="CartItems[1].Quantity" value="1">
</form>
This is the jQuery code that handle the submit event for the form
$("#cartForm").submit(function (event) {
event.preventDefault(); var form = $("#cartForm");
var panel = form.parent(); panel.parent().block();
$.ajax({ type: "post", dataType: "html",
url: '<%: Url.Content("~/Order/Checkout") %>',
async: false, data: form.serialize(),
success: function (response, status, xml) { panel.parent().unblock(); },
error: function (response) { panel.parent().unblock(); } }); });
This is the controller action that should be get called
[HttpPost]
[ValidateAntiForgeryToken]
public virtual ActionResult Checkout( CartModel cart ) {
} And finally this is the CartModel class involved
public class CartModel : BaseModel{
public int CustomerID { get; set; }
public int FirmID { get; set; }
public List<CartItemModel> CartItems { get; set; }
public CartModel() { CartItems = new List<CartItemModel>();
} } public class CartItemModel : BaseModel
{ public int ServiceTypeID { get; set; }
public int Quantity { get; set; } }
But the default Model Binder does not bind the web form data to a CartModel class. Using Fiddler I have been able to see that the data sent to the server is correct as you can see from the following snapshot.
