  - by Hurricanepkt

  Just installed the trial version of Visual Studio 2010 RTM. Now I keep getting : The name 'NoPanel' does not exist in the current context Errors (where no panel is just about any control in the .aspx file) also I got several errors trying to deploy pages and it would not send the .cs file over ...or pdfs in the Content directory (even though I had copy always set)...

• Does it make sense to have a model with only static methods?

  - by Jamie Dixon

  Hey everyone, I have an ASP.NET MVC 2 project that I'm working on and I'm wondering where I should place some of my code. I currently have a UsersModel which consists of a bunch of static methods that operate against my data context. These methods include such things as: UserExistsInDatabase, UserIsRegisteredForActivity, GetUserIdFromFacebookId etc etc. Should these methods be inside a UsersModel class or would they be more suited to a user helper class outside of the models context? Cheers for any pointers.

• Passing a model into RedirectToAction()

  - by larryq

  I'm curious how this works. In MVC you can call View() and pass a model as a parameter, but RedirectToAction (one of its incarnations at least) takes a 'routeValues' object, which appears to be the closest match. If your model is passed in this parameter will that model type be available in the subsequent action method? Or are there caveats involved that might prevent accurate translation in some circumstances?

• Is it okay to mix session data with form and querystring values in a custom model binder?

  - by Byron Sommardahl

  Working on a custom model binder in ASP.NET MVC 2. Most of the time I am binding data from typical form or querystring data. There are times that I end up letting the model binder bind part of an object and get the rest out of session at the controller action level. Does it make better sense to bind the entire object from the model binder (e.g. querystring, form, and session)?

• Authorization security of ASP.NET Forms authentication

  - by Tomi

  I'm using Forms authentication in ASP.NET MVC website and I store user account login name in AuthCookie like this: FormsAuthentication.SetAuthCookie(account.Login, false); I want to ask if there is a possibility that user on client side will somehow manage to change his login name in AuthCookie and thus he will be for example impersonated as someone with higher privileges and authorized to do more actions than he is normally supposed to have. Also is it better to save in this cookie user account login name or user account ID number?

• loading method based on URL

  - by steeped

  I am trying to build a small mvc-based application. How do I call a method in a class based on a query string? For example, the $_GET query string is being set as load_master_form http://www.domain.com/settings/load_master_form And to call the method within the settings class, I am doing: function __construct(){ $this->{$_GET['method']}(); } But obviously that doesn't work - it just isn't possible to load a method like that. So how would it be done?
