i currently work on an asp.net mvc 2 project and noticed that inside an asp.net mvc view page i can get the user name authenticated via User.Identity.Name, but if i try to use the DsiplayFor method in order to display my model from a view user control, it just does not exist. Could i pass this parameter to my model using additional ViewData parameter that comes with DisplayFor html extension?

I want to execute some logic if the Logged in User can view a page "~/MyPage.aspx". IF the logged in user should be elligible to view the page is determined by the role based security I configured in the web.config file. There are many methods to find out if the user is in role XXX or not. But I did not find any method to find out if the user can view a page or not ahead of transferring the user to that page. Maybe I will hide a link to a specific page to the logged in user if the user is not elligible to view that page if I know the technique i am asking here to know.

Basically I have a page where a user can select up to 3 vehicles by make and model. I have 3 divs on the page that is generated with a basic foreach loop. When the user selects a make and model from respective dropdown lists I am firing a javascript function that returns a JSonResult that loads a dynamic partial view into a seperate div. This partial view displays a div with a grid whereby the user can select one of n-number of services using a checkbox.Next what I would like to do is if the user selects a servce for the one of the vehicle selections, I would like to add this selection to a list of "ServiceSelection" that is part of my viewmodel. Ultimately the user would click a button that would redirect to the next step in the process and pass the entire updated viewmodel to this new page.

View 2 RepliesI have a simple user control containing two text boxes which I am adding to placeholder on Button Click event. I am storing the number(count) of clicks in View state and running a loop using count to create all previously added user control. I am also adding IDs to each User control (appending "UC" and count). I have also checked in view source the ids are same each time they are created. I have another button which basically does an post back. I have EnableViewState enabled ="true" in all controlls all the way up to Page Level. My problem is that User Input does not persist on postback. Should this not be happening automatically for me?
