MVC :: Removing ActionMethod Property From Action Filter Contexts?

Nov 17, 2010

I'm trying to get the current action method by this way.

ActionDescriptor actionDescriptor = filterContext.ActionDescriptor;
string actionName = actionDescriptor.ActionName;
var controllerType = filterContext.Controller.GetType();
var actionMethod = controllerType.GetMethod(actionName);

But if there're two action method with the same name, the AmbiguousMatchException will occur there. Without the ActionMethod property, how can I get the current action method now?

C# - Run Both Authorize Filter And Action Filter On Unauthenticated MVC Request

Mar 17, 2010

I have decorated my base controller with a couple of action filters. They work fine.

One of those filters sets up the request - does things like set the culture based on the domain, etc.

I also have a handful of actions that require authorization using the Authorize attribute.

My problem is that when an user attempts to request a page they are not authorized to access, the authorization filter kicks in and redirects them to a page telling them that they cannot vie the page.

The issue is that the action filters never run so the culture and other request data is never set. This effectively causes language to be wrong in the view and other data to be missing.

I know that authorization filters run first but my question is this: How can I design this such that I can ensure that certain methods are always run before the view is returned, regardless of the authorization.

MVC :: Is There A Way To Handle Dynamic Forms Using ViewModel

Sep 15, 2010

I need to create a dynamic form using the already existing DB entries, from 3 different tables. I am trying to do this by inheriting ViewModel class, which is comprised of all the model instances (or List of instances of unknown count) within it.

When I inherit the ViewModel in the View Template, the dynamic form gets generated without any issues, and looks fine. The dynamic form is generated based on iterating over the calls for each required model instance in the ViewModel passed to the View.Each call uses a partial view of the instance to generate the form, and hence multiple iterations create multiple instances of the form.

[Code]....

However, when I try to submit the form, the postback does not include the ViewModel object, but rather only the first model instance used in the form.

MVC :: Edit The Content Of A View From An Action Filter?

Jan 6, 2011

Is it possible to edit the content of a view from a action filter.

What I am working on is a Resourcemanager that I can use to manage

my style sheets, js and other resources. I want to be able to put

lines in the the view any where like Html.ResourceManager.AddScriptFile("MyScript")

or Html.ResourceManager.AddCSSFile("MyCSS")

and at the end of the view call Html.Render(); this would then place the content of my resources at this point. My problem is that I want to put the CSS stuff at the top of the view, but them problem is that it is renderend at the end of the view, so I tought that I could use a ActionFilter to move it to the top of the view.

1) What would be the best way to do this task ?

2) Is there any resources that describe the way that the MVC framework works in more detail ?

MVC :: Action Filter Attribute Breaking Change?

Jan 20, 2011

I have an app I am transitioning to MVC3 to see what the upgrade path is essentially. I've hit a snag. I believe I've run into a change that may be due to the changes for Dependency Injection in action filter attributes, but I have been unable to track down the cause, and the "correct" solution.This project uses StructureMap and NHibernate. The NHibernate session is started at the beginning of each request, and ends at the end of each request, thanks to a small module. This is just to give an idea of the stack involved...o I have a few custom Authorize attributes (Inheriting from AuthorizeAttribute) that perform some more complicated authorization logic for specific actions that they decorate. Part of their functionality involves using two repositories which they must either (a) have injected, or (b) get from the StructureMap ObjectFactory themselves. In MVC2 I was using option b, so that the CONSTRUCTOR of the attribute looked like this:

[Code]....

This worked fine, as in MVC2 the constructor was called each time the attribute was evaluated. This BREAKS in MVC3, where it would appear that this is no longer the case. Due to this apparent change, the FIRST time this attribute is evaluated, it runs fine, but each subsequent time, any calls in the repositories fails because it claims the NHibernate Session object hasn't been started! The reason being, as far as I can tell, that the CustomAuthorizeAttribute is created once, and then held in whatever state it exists in at that point for the lifetime of the application... Which means that the dependencies inside of it (Which SHOULD go out of scope at the end of each request, and be reinstantiated / fetched at the beginning of subsequent requests), are instead persisting with it becoming stale after the first evaluation.After banging my head against the desk for a few hours, I realized that simply moving these calls to the ObjectFactory into the AutorizeCore method made everything work again.Now, all of this was of course, a hack, because there wasn't a good easy to do real dependency injection into attributes in MVC2. I hear that is changed in MVC3, and I am wondering if this behavior is in response this change, and if so, what do I need to do to make this work?

Forms Data Controls :: Define A Static ItemTemplate For A Dynamic DataList?

May 22, 2010

I must create a few DataLists programmatically. All of them will share the same ItemTemplate. Is it possible to define this ItemTemplate in .aspx file, using wizard etc, and then create DataList programmatically and assign this template? There is information in the internet how to define both ItemTemplate and DataList programmatically, but I want to define the ItemTemplate statically and only DataList programmatically and then assign the template to it.

The problem that I encounter is that ItemTemplate tag only works inside some control tag. It looks like it is impossible to define an ItemTemplate (like e.g. resource in Silverlight) not associated with any DataList, using the wizard and design tools, and then reference this template in code during runtime.
