ASP.NET MVC2: How to return a file from a controller? I want to do this so the user can download the file from server.
my MVC2 delete and only my delete controller is refusing to return any class information. Its really similar to my edit function and the views are all auto-generated so I don't see the problem.
Function Delete(ByVal id As Integer) As ActionResult
Hi I have created the following controller i want to add view that should have the data access class UserMagnament.Controller.menuitems but when i add view by right clicking on view folder,it is not showing "UserMagnament.Controller.menuitems" in add data class
No controller is shown such as homecontoller, accounts controller, UMController(My Controller) etc i have converted my solution from mvc 1 to mvc2. i checked the web.config. it seems ok for MVC2
[Code]....
In MVC2 does every single controller method have to map to a DIFFERENT view?Or can I make two methods map to the same view?
View 3 RepliesI have a HTML table (grid). I want to pass the html table data to controller.(mvc 2.0)
View 2 RepliesI am posting a Jquery Json serialized object to my controller but not all of the data is getting passed. One of the members is a complex type that is also Json serialized. This is the one that isn't getting through to the controller.
Here is the class I'm passing to my controller via Ajax post. Note the complex type, RoutingRuleModel.
SourceCodeModel.cs:
[code]....
Problem: SourceCodeModel contains correct values EXCEPT for it's complex member: RuleModel, which comes back as a RoutingRuleModel with default (null or 0's) values.
Seems like there are a lot of ways to solve this problem.
Currently I make a partial view with a form like so:

What are other ways to accomplish the same thing and what are the pros and cons vs what I am doing?
Is Ajax.Form useful?
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?
If I have a controller and I want to return a view based on what my conditional logic goes to, is that possible? I have different types of models that i want to insert into a view DEPENDING on my conditional logic (if statements) Can i do this? and how would I do this
View 2 Repliesgetting data from multiple Entities models into an MVC controller. Most of the examples I have seen for using EF in an MVC2 app only use a single entitiy.
I have just started using MVC2 in C# using the Entity Framework models (CIOps.model) created from an SQL database. I can create the controller and views using single tables of the model in MVC2, but I just cannot get my head around how to get data from multiple entity tables into the controller (similar to joins in T-SQL). I have included an example below of the controller code that works with a single entity table, tbl_tours (tbl_tour in DB).
Could someone please illustrate how this code would be changed to include additional columns from FK tables in addition to tbl_tours columns. E.g. the clients name from the tbl_clients, the coordinators name from the tbl_employees, and costs from tbl_costs entities? Is it possible to do this directly using the EF model entities/classes that are already created and not use LINQ, POCO, Repositories, etc.? The FK relationships are already in the EF models. I have included the whole controller code, but I just need a few examples of how to join the multiple entities, not rewrite every CRUD function function in the controller. I think this will get me over the hump in using EF in an MVC2 App. Also ignore the fact I am using the home controller, this will change in the application.
[Code]....
I have a controller with several actions that all return a set of data that's the same among them all. Instead of adding the data to the ViewBag in every single action, is there some pattern or attribute or something I can call or set to add the same data to the viewdata or viewbag for every action, or some other better way to perform the get the same data in every view without calling the method in every action?

I am fairly new to MVC and just trying to achieve something which I think shouldn't be too complicated to achieve. Just want to know what the best approach for that is. I have an Event-RSVP application (NerdDinner kind) where you go to view details of the event and then click on an AJAX link that will RSVP you for the event.
<%
if (Model.HasRSVP(Context.User.Identity.Name))
{
%>
<p>
You are registered for this event!
<%:
Ajax.ActionLink("Click here if you can't make it!", "CancelRegistration", "RSVP", new { id = Model.RSVPs.FirstOrDefault(r => r.AttendeeName.ToLower() == User.Identity.Name.ToLower()).RSVPID }, new AjaxOptions { UpdateTargetId = "QuickRegister"})
%>
</p>
<%
}
else
{
%>

I have a list of items(surveys) displayed on my home page. When I click the edit button for a particular item I have a modal pop up with the items details to edit. When the user clicks Save I submit the form via ajax. Depending on whether ModelState.IsValid == true I want to update the modal with validation information or close the modal and update the list of items with the new information.
This is how I am submitting the form:
[Code]...
My Questions
The only thing I can think to do is return JSON from my controller with a flag indicating the state of the ModelState.IsValid and the corresponding partial that I should show.
1) How would I do this?
2) Is there a better way?
Update
I found this: [URL]
but it seems more likely that I am going about the whole thing incorrectly.
display the first tier of data so the user can select and tweak desired rows. On occasion, they will want to drill into a row to see the children and select/tweak them. After a tweaking session, I wanted to be able to commit.
If I build an aggregate ViewData and prepopulate it, I can display it just fine in the View, and I get the collection back in the postback just fine.
Starting with empty child data, I experimented with jscript to fetch that data and displayed it by adding elements with jquery.
What I can't figure out how to do is to return that data to the controller. The newly added elements aren't in "Show Source" ... I heard elements added via jscript are not posted back. I even tried adding items to a prepopulated list ... only those items originally passed in are returned.
I have an application that has an public 'end user' mode and a 'back office' mode. Both 'modes' pretty much share the same controller logic but the user interfaces for these different 'modes' are radically different. Using the out of box default routing that you get when a project is created for the first time I have something like the following:
Controllers
HomeController.cs
Views
BackOffice
Index.aspx
Public
Index.aspx
Shared
BackOfficeSite.Master
PublicSite.Master
In my HomeController.cs I have logic that looks like this:
public ActionResult Index()
{
var devices = DeviceRepository.FindDevicesByCustomer(100);
if(IsBackOffice())
{
return View(@"~/Views/BackOffice/Index.aspx", devices);
}
return View(@"~/Views/Public/Index.aspx", devices);
}
Is this the correct way to be doing this or am I digging myself an anti-pattern hole? I'm using ASP.NET MVC 2.

How does a controller action return an HTML stream as the View? ( in place of the name of the View file )
I want to return a simple "error detected" or "action completed" page to the browser. And I dont want to clutter up my project with yet another view. The return string being "<html><body><h1>Error. Customer xxxx is not found</h1></body></html>"
( thinking about it, better to have a general purpose view in a folder named "Common". Then pass the message text in ViewData. Still curious to know how to return an html stream. )
I want to do is to get the record number in my database of the first record that matches my search. Its to skip to a random point in the database based on user input.
[Code]....
It returns the number of records that preceed the first one to match the string. I have tried to call this procedure from MVC and it always returns -1, so I have a fundamental problem there. I have also tried ot figure out how to just duplicate the code in MVC and I also cannot seem to get anywhere on that front.
Does anyone know a simple elegant solution to either embed this code diretly into MVC or to call my stored procedure from MVC and get the correct integer response back, instead of -1? I am engaged in relearning development after many years, so I am getting stuck on the basics.
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 am getting the above when I try and open a view in a controller in an Area. Ninject is set up as follows:
public class NinjectControllerFactory : DefaultControllerFactory
{
private IKernel kernel = new StandardKernel(new RLSBCWebSiteServices());

Has anyone managed to get Areas working with NinjectControllerFactory, or is there something wrong with my set-up?
I want to know two things about ASP.NET MVC2 that I've researched from Google but still confusing. Hope I can find clear and clean answer here.
First, how to upload a file to server with custom file path. (Eg. to /Content/Files)
Second, how to download that file, since the url has applied URL Rounting, how to map to them?
We have a mid-sized asp.net project that we just promoted from our dev server (Windows 2003) to an external test server (Windows 2008 R2). On the test server, IIS is not finding our home page, which is located in the views/home folder (404 error). As far as we can tell, the settings are the same on both servers. I've confirmed HTTP redirection is installed. Is there perhaps some critical configuration we may have missed on IIS7.5 to let it know where to find the view and/or home page?
View 2 RepliesUML and Patterns: An Introduction to Object-Oriented Analysis and Design and Iterative Development, that follows the UP(Unified Process). It uses a Grasp Controller pattern to interact with domain classes by some methods like NewSale(), AddNewItemToSale() and CloseSale. In windows form, I can instantiate a object of this class in the UI and then use its methods to perform the actions. This works well in Client apps, but when I use asp.net mvc, I cannot find a way to instantiate an object (one for each user) that was always visible for a Controller (MVC). I cannot insert as an attribute inside Controller because it always create a new one.
