ASP.NET MVC: What is the correct way to redirect to pages/actions in MVC?

- by Mark Redman

I am fairly new to MVC but not sure exactly which Redirect... replaces the standard redirect used in WebForms ie the standard Response.Redirect() For instance, I need to redirect to other pages in a couple of scenarios: 1) WHen the user logs out (Forms signout in Action) I want to redirect to a login page 2) In a Controller or base Controller event eg Initialze, I want to redirect to another page (AbsoluteRootUrl + Controller + Action) It seems that multiple redirects get called in some cases which causes errors, something to do with the fact a page is already being redirected? How can cancel the current request and just redirect?

ASP.NET MVC: trying out a script injection hangs Visual Studio 2010 completely?

- by Mark Redman

Wondering if anyone has an idea of whats going on: I am new to ASP.NET MVC and am trying out a few things with jquery/ajax. The basic scenario is a dropdownlist with an add button next to it. Clicking the add button launches a jquery ui dialog with a textbox form, entering a value saves the item to the database and refreshes the drop-downlist. The dropdownlist is re-populated using a JSON result. This all works ok. I thought I would try a script injetion attack, ie add the text: alert("oh dear") to seee what would happen and to check if I need to encode anything. When I try and save this item (similar to the same process of adding a plain text entry) Visual Studio 2010 Beta 2 hangs completely. Any ideas? UPDATE: It happens when posting: "</"

Are there any programmable barcode scanners that can call a webservice?

- by Mark Redman

I am looking at integrating a C# application with a barcode scanner. The last time I did this was with Delphi 1 (win 3.11) using a scanner that plugged in-line into the keyboard cable. Looking around it appears most scanners are USB based these days and assume they emulate keyboard entry. Anybody know of more sophisticated/programmable scanner that can call a webservice or even just do a basic POST/GET this would eliminate the C# application and the computer to support it?

ASP.NET MVC: How to create a basic Pseudo Viewstate? Or better solution?

- by Mark Redman

I am newish to MVC and understand all the great things about it, including the reasons why voewstate isnt available, however there are some circumstances where I think having some kind of view state will be quite handy, In my case I am thinking about list pages with various search filters that can be applied to the list. Would it be worthwhile implementing some kind of pseudo viewstate to hold this info in some cases? or is there a better solution? Any examples out there? Your comments appreciated.

SQL Server: Deleting Rows with Foreign Key Constraints: Can Transactions override the constraints?

- by Mark Redman

I have a few tables where Foreign Key constraints are added. These are used with code generation to set up specific joins in generated stored procedures. Is it possible to override these constraints by calling multiple deletes within a transaction, specifically "TransactionScope" in C# or is cascaded deleting absolutely required?
