i have a viewmodel with two entities. one is named Customer. in view validation is enabled for Customer using the entity state (isvalid, ...)
in to post action to the controller the entity state is "Detached". I believe this is as it should be.
My question is: How can the Customer Entity be checked for state change? I can create a new entity to check, but this has its own issues.
Being new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

I'm a php programmer (code igniter) but interested in learning ASP.net MVC, I have a few question regarding this new exciting framework In php codeigniter's controller I can easily catch a post variable using

Or using FormCollection

Is there a way to catch post variable in ASP.net that looks like php's codeigniter? I mean not by adding the parameter, because I wanted a controller method that is flexible in receiving post request A controller that can accept and process any post request like in php (where we don't have to put that parameter to the controller method, we just call them

Post form data to controller without page refresh in asp.net mvc application using Jquery ajax.
View 1 Repliesia ma working on an asp.net mvc 2 app and i have a Users view, displaying all the users of the database. Then, i would like to add the ablility to display "users starting with fisrt name" capabaility on the same view. For this i created a list of all english leters that actually are links (<a href="#">A</a>, etc...)
I managed to handle the click event of each one of the letters and get the corresponding letter via jquery, but i don't know how to call theHttp.Post Users/FindUserByFirstLetterName(string letter) on the click event.
I cannot use the Html.ActionLink<> helper, since it redirects me to the HttpGet controller action.
I also tried using using jqery.Post but i also couldn't manage to call the action.
I'm gonna create profile page for my site. This page includes some 'Partial View' and each part posts some data.
My question is: How can I get posted data (strongly typed) from each partial view separately? Something like this:
[HttpPost]
public ActionResult Home(Model1 model1, Model2 model2, ...)
{
return View();
}
I got a list of checkboxes on my form, and a jquery script that catch a button click to get all the selected items (in an array) and post to a controller action.
This is my script: (yes A, looked at your sample but cannot get this to work)
[Code]....
That alert will print out correctly (like 1,3,5).
However when the above post hit my controller action, "selectedInvestments" are null, which I can't figure out why (back to my tekpub jquery videos, can't go on like this)

I'm fairly new to MVC and admittedly don't fully understand how data is passed between Views and Controllers. That said, here is my issue.
I am working with C#. I have a page which has a list of items. Each item has a radio button set of three associated with it and there are 15 of these sets on the page. Thus I have radio1, radio2....radio15, etc. Each of these has value 0, 1, or 2 upon submit. I can't seem to understand how to get the information out of these radio button sets from the controller without passing 15 different variables to the post method in the controller which is associated with the view; ie passing Int32 radio1, Int32
radio2,.., Int32 radio15, etc.
I tried using ViewData["radio"+i] in a loop to access the value of each radio button set, but this, apparently can only be used to pass data to the View from the Controller and not the other way around.
i have a website where i provicde a link. On clicking the link a controller action method is called to generate a zip file after creation of zip file is done, i show the link to download the zip file by replacing the link to create a zip with the link to download the zip.
the problem is that after zip file creation is over and link is shown, when user clicks on the link to download the zip file, they are sent to login. After providing correct credentials in the login page they are prompted to download the zip file. they sould not be sent to the login page. In the action to generate zip file i haven't abondoned the session or haven't not done anything that abondons the session.
the user should not be sen't to login page after successful creation of zip file user should be able to download the file without login. i search internet on this problem, but i did not find any solution. In one of the blog written by hanselman i found this statement that creates the problem with the session: Is some other thing like an Ajax call or IE's Content Advisor simultaneously hitting the default page or login page and causing a race condition that calls Session.Abandon? (It's happened before!)
so i thought there might be some problem with ajax call that causes the session to expire, but i don't know what is happening? it's like this after users click on the link to create zip file the zip file is created successfully but the session gets expired. this is not what i want. Why does the session has to get expired after making a jquery post call to controller action to create a zip file? i hope u understand the problem.
UML and Patterns: An Introduction to Object-Oriented Analysis and Design and Iterative Development, that follows the UP(Unified Process). It uses a Grasp Controller pattern to interact with domain classes by some methods like NewSale(), AddNewItemToSale() and CloseSale. In windows form, I can instantiate a object of this class in the UI and then use its methods to perform the actions. This works well in Client apps, but when I use asp.net mvc, I cannot find a way to instantiate an object (one for each user) that was always visible for a Controller (MVC). I cannot insert as an attribute inside Controller because it always create a new one.
View 1 RepliesI'm displaying the values in ViewData.Model in a View (.aspx) -- After the user looks them over, when the user clicks the "Submit" button that I have in this view, I want the ViewData.Model passed to another controller, but I'm not sure how to do this.
Currently, my target controller/action looks like this:

The "ViewData.Model" variable in this View is of type: List<Sample>
How do I pass the ViewData.Model to the RegisterController / Samples (action) ?
I'm trying to add file upload functionality to a page. I've got a form that posts the selected file to a controller with a 'savefile' method. But if I don't add a get version of 'savefile' I'll get a 404 error. Here is the form code which is presented on the Index page:
[Code]....
And here is the controller code:
[Code]....
Intuitively I don't think I should need a GET version of SaveFile but if omit it I get a 404 error when the form posts. Why should I need a GET version of SaveFile when all I want is to post a form and save the file?

I have a simple model where a Person has Gifts. I have a view which is a list of Gifts belonging to one Person.
My problem is with the Create action for a new Gift. I want it to default to the PersonID that we are already viewing the list of Gifts for. I tried simply passing the last PersonID (they are all the same)
Html.ActionLink("Create New", "Create", new { id = Model.Last().PersonID }) which works fine if there is already at least one Gift for that person but if this is the first Gift I don't have a value.
My Gift List controller knows the PersonID I want to pass but the view doesn't.
How do I pass this PersonID from my Gift List controller to my Gift Create controller via the Gift List view? Or is there a better way to do this?
I have a filter on my MVC web site. I display some records in a few different controller actions but when moving from one action to another I want to apply those filter values.
How can I persist values from controller to controller?
Should I use Session? TempData?
I am using Structure Map for IOC.
Maybe I could have a class that contains a Property for each Session Value that I use in my application and inject it on the controllers that need session?
