MVC :: State Management On A Multi-page Wizard?
Jul 26, 2010
I'm working on a pretty generic product purchase wizard that takes a user through a process to purchase items in a shopping cart. I am implementing it in MVC2 on Azure without session state. I want to do the following:
GET ShippingInfo calls ActionResult ShippingInfo()
POST ShippingInfo calls ActionResult ShippingInfo(ViewDataObject v)
In ShippingInfo action, I need to validate shipping info. If validation fails, it should redisplay the ShippingInfo view passing the ViewDataObject. If validation success, I want to display the ConfirmView using the posted ShippingInfo data in the ViewDataObject.
I have tried the following:
1) Called RedirectToAction("ConfirmView") but this requires the ConfirmView get method to read the ViewDataObject from cache or a database which I want to avoid if possible
2) Called View("ConfirmView") within the ShippingInfo action on validation success but the URL doesn't change so the back button doesn't work properly
3) Changed the form on ShippingInfo to post to the Confirm controller but then if validation fails the URL is on the Confirm page
I really want to just pass the limited form data from ShippingInfo to the ConfirmView. I then I have everything I need on the Post/Submit from the ConfirmView. Also I want the url to be /Order/Confirm when on the confirm page.
Is there a way to do this without TempData or session state?

If affinity is set to use multi core, aspnet_wp would be run individually on all cores.
So sessionstate, application and cache objects would be core specific. Is this understanding correct ?
Is there a way to share state - session, cache objects?

i have a form on page1.aspx with several controls (textbox, dropdownlist, etc).on Page1 PageLoad event i load data from database and performe databinding.From Page1 a user can, by clicking a specific button, move to Page2.aspx to insert some details and, after saving details, he returns to page1.
if save changes are made on control on page1 before save them to db, obviously, these are lost on return from page2 (because are reloaded on pageload from db).How can i save control status between pages round trip?

I am creating a wizard. One of the requirements is to display where the user is in the workflow (ie: Step 1 of 5). My problem is at any point the steps remaining could change depending on what the user answers. Let me highlight with an example.
Q1: What is your name?
Q2: What is your age?
(a) 0-18 => User selects a, there are 3 questions remaining
(b) 19-65 => User selects b, there are 4 questions remaining.
(c) 65+ => User select c, there is 1 question remaining.
So in Q1, there is no way to know which answer the user is going to pick in Q2. What would I display to the user in Q1? Has anyone encountered this before? If so I would love to hear your opinion. Please keep in mind that the example is simplified and I have many branches in my workflow.

I'm in the process of redesigning a creation wizard in our ASP.NET MVC 2 application.Our current method is to have different pages for each step and navigate between them. While this works, it's a bit slow and annoying to navigate.I was looking to use JQuery and AJAX to make this feel a bit more dynamic and to also use client side validation.I have investigated using Ajax.BeginForm() to post back the individual steps of the wizard, and have that post return the partial view containing the new form with the next step of the wizard. That way, I can do client-side validation on each step.With this in mind, is Ajax.BeginForm() a better method than using the JQuery form plugin? Has anyone found any major issues with either approach?

Here is my scenario.In default.aspx page user selects the country, state, city from drop down list, and store them in cache for further use. but when other user open the web site from other computer it shows the same country, state, and city selected by user 1. Is there any problem related to cache? I have stored data as following.
cache["ctryID"] = ctryID;
cache["stateID"]= stateID;
cache["cityID"]= cityID;
I want to show default country, state , city at page load of default.aspx

I am using query string to pass values from page 1(log in page) to page 2 and then page 3. I have an .ascx file also, so how can I import the user name from Page1(login.aspx) to menu.ascx file. So that when I click the menu Home the value of the variable remains at the website. I am not aware of session handling thats why I am using this method to pass the valus among the various pages in website.

I have a Web Application where I have one and only one master page and with 100's of diffrent content pages
So to speed up my Web app How can i CACHE the mater oage but not the content page??
Master page loads each time whenever content page is requested..
This thing is possible,I have seen it on many diffrent websites where the Website's Master Page Remains Intact and only the content page changes (best example would be Facebook)
How can i have the same effect in my Web Application?

In logout link's click event i have written Session.Abandon() that will destroy the Session state.I am also handling Session_End event that is fired afterward (written in Global.asax). But one more thing i want is that after Session ends, login page should be redirected (opened).
For that i wrote:
[Code]....
This is working fine on the surface, but after applying debugging i saw that there were unexpected number of calls to Session_Start and Session_End events for two times, then login page was opened.
Why Session_Start and Session_End was called two times ? If i left this process as it is working then may i get some serious error in future ?
