Informing The Client / View Of Exceptions Caught By The Controller?
Dec 18, 2010
I have basic client-side validation working in my MVC3 RC2 application, but I'm now interested in recommended practices for conveying server side validation errors, as well as server side exceptions, to the client. I know I can add properties to my view model and display these if populated, but I don't want to reinvent the wheel, and I would like to tie in with MVC's way of doing things. So, how should I, a) notify the user of server side validation errors, and, b) notify the user of server side exceptions, e.g.

When doing some custom validation on DateTime fields the thrown exceptions are not caught and simply cause the application to end.

I know there are a few posts on this issue already, however I haven't found the answers I was really looking for.
My situation is like this: I have a DLL project containing my business logic. Then I have a web application that refers to this DLL, and calls a function from it. And I have a global.asax which handles errors on Application_Error
Sample:
// MyWebsite.aspx.cs
using MyBusinessLogic;
protected void Page_Load(object sender, EventArgs e)
{
MyBusinessLogicClass.DoSomething();
}
// global.asax.cs
protected void Application_Error(object sender, EventArgs e)

What's the best way to handle exceptions that happen from within a controller's constructor?
All I can think of to do is use Application_OnError() or put a try/catch in my ControllerFactory.
Neither of these solutions seem ideal. Application_OnError is to broad - I have some non-mvc content in the site that has its own error handling. Using a try/catch block seems kinda hacky.
If I'm serving different content type -html/text/json/rss.... I would like to be able to handle the exception from within the action method instead of having to write all kinds of conditions to determine what kind of error message to serve.

I have a simple model where a Person has Gifts. I have a view which is a list of Gifts belonging to one Person.
My problem is with the Create action for a new Gift. I want it to default to the PersonID that we are already viewing the list of Gifts for. I tried simply passing the last PersonID (they are all the same)
Html.ActionLink("Create New", "Create", new { id = Model.Last().PersonID }) which works fine if there is already at least one Gift for that person but if this is the first Gift I don't have a value.
My Gift List controller knows the PersonID I want to pass but the view doesn't.
How do I pass this PersonID from my Gift List controller to my Gift Create controller via the Gift List view? Or is there a better way to do this?

I've been developing a web application (C#) that has to send an e-mail to around 10 users, how ever, when the user clicks the button is like nothing happened cause the server is processing the e-mails. After the emails have been sent the site is redirected to another page that I have set up, but it takes about 10 seconds until it happens, that way the user will think that the system is frozzen.I'd like to know how do I do to after the user click the Submit button show an advice. I was thinking about put a label, and after the click, the text would change to "Sending the emails", however, I'm making a loop to send the emails, and I believe that if I put the code changing the text before the loop I'll get nothing, once the page will refresh after the loop's execution, am I right

I'm building the standard 3-tier ASP.NET web application but I'm struggling as to where to do certain things - specifically handling exceptions.
I've tried to have a look around on the web for some examples but can't find any which go as far as a whole project showing how everything links together.
In my data-tier I'm connecting to SQL Server and doing some stuff. I know I need to catch exceptions that could be raised as a result but I'm not sure where to do it.
From what I've read I should be doing it in the UI tier but in that case I'm not sure how to ensure that the connection to the database is closed. Is anyone able to clarify how to do this? Also if anyone knows as to where I could find an example 3-tier web application that follows best practices that would be great too.

We have a asp.net application and want to implement logging. The first idea was to use the Application_Error method in the global.asax file.
The problem is that ASP.NET very often seem to throw exceptions internally that are not caused by the application and which seem not to interfer with the users normal workflow. For example we often get HTTPExceptions, UnauthorizedAccessExceptions and others caught in this method, although there is no real error in the application.

I have a View:
<div class="editor-field" id = "nick">Nick <%: Html.TextBoxFor(model => model.Nick)%><img src="/Content/Images/loading.gif" alt = "loading...."/>
<%: Ajax.ActionLink("Check", "Check", new AjaxOptions { UpdateTargetId = "check-valid", LoadingElementId = "loading"})%>
</div>
I used: Nick = ViewData.Model.Nick in ActionLink as below, but I cannot get value of Nick from View.
<%: Ajax.ActionLink("Check", "Check", new {Nick = ViewData.Model.Nick}, new AjaxOptions { UpdateTargetId = "check-valid", LoadingElementId = "loading"})%>

I came upon this when had problem trying to return a view of a different controller.
In controller1, I have view view1.
In Action1 of controller2, I wanted to do something like:
public ViewResult Action1()
{
return View("/Controller1/View1");
}
but, found out, I couldn't do it. So I searched and found this:[URL]
One guy there responded and said that, for my case, it is possible to do things like below:
return View("~/Views/Controller1/View1.aspx");
this is considered an acceptable MVC practice. Is it OK, good, perfect to do so in the asp.net MVC realm?

I have a view that receives a Model and displays info of that model.
I have a submit button and when it is clicked i want it to send the id to the method to process it and delete a row that has such id.

@Html.ActionLink("Delete", "Delete", new { id = Model.Id }) |

I'm a newbie and I tried finding a solution of this error message:
"The model item passed into the
dictionary is of type
'NerdDinner.Controllers.DinnerFormViewModel',
but this dictionary requires a model
item of type
'NerdDinner.Models.Dinner'"
There are similiar problem error but not the same context problem. I believe that the problem is located in the edit.aspx and still i can't solve it.
DinnersController:
//
// GET: /Dinners/Create
public ActionResult Create()
{
Dinner dinner = new Dinner()
{
EventDate = DateTime.Now.AddDays(7)
};
return View(new DinnerFormViewModel(dinner));
}

I'm a php programmer (code igniter) but interested in learning ASP.net MVC, I have a few question regarding this new exciting framework In php codeigniter's controller I can easily catch a post variable using
[Code]....
In comparison in ASP.net MVC we can create an action method that will accept post variable (but the parameter can get very crowded if we're passing a lot)
[Code]....
Or using FormCollection
[Code]....
Is there a way to catch post variable in ASP.net that looks like php's codeigniter? I mean not by adding the parameter, because I wanted a controller method that is flexible in receiving post request A controller that can accept and process any post request like in php (where we don't have to put that parameter to the controller method, we just call them

I have setup an httppost that sends a string into my controller, searches for some results using linq, and then sends the results to a view. In debug stepping through the code I can see the data that I am looking for being passed into the return view statement, but the page just appears to refresh (it doesn't render the view as expected with the result). why my controller fails to redender the view? (note: I didn't include the view because I can send a ToList() to it without an issue. For example, return View(_entities.Persons.ToList());
[HttpPost]
public ActionResult RenderSearch(string usersearchtext)
{
if (usersearchtext != null)
{
var search_results = from s in _entities.Persons
where s.Description.Contains(usersearchtext)
select s;
return View("SearchResult", search_results.ToList());
}
else
{
throw new NotImplementedException();
}
}
