I'm trying to realise how to make a div on the page hidden, from the controller.
the situation is this:
i have 2 radioboxes, which need to fill a hidden label with thier value, dependant on the one selected.
the second case is gettin the value in the ID part of the link, and hiding the radioboxes altogether.
been googling it for hours and could not find a solution for this?
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 have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.
Can I reach the value of hidden fields in controller action ? And how ? Do I put it in the model somehow ?
EDIT: some code example how to store something in hidden field and retrieve it on postback.
I'm working on a mvc project that builts a table of items and each row has a button to submit that row to the controller. Now each button has an id and I use hidden input to store the data in that column. How do I post the id to the controller? I use Html.beginform() at the beginning and a submit button. I want the ID to appear in the URL so I can extract the data based on that.
Also I can see that my values are posted but they don't show up in the query string. How do I get these values in the controller? The code is like this. [Code]....
I'm using V.S. 2008 and asp.net MVC. I have a form in this page that user selects various items from Select controls. I then construct a string varible that contains each selected element's id a hidden input control that holds this information. How can I pass this variable (and it value of course) to a Controller Action? I am using regular Html Form and the Submit button.
In the following code you see the "ResearchInterests" is the one that holds the string but I can't even reference it in my Controller action, Search. How can I correct this?

<%=Html.ActionLink<PersonController>(x => x.Publications(param1, param2, ... )) %>

View 4 RepliesThere are two frames. In ASP page 1 that is being displayed in frame 1, we have a form with hidden variables. On some action this from is submitted to frame 2 with action as ASP page 2 (target = frame2, action = 'ASP Page 2') using POST method. But on ASP page 2 when we try to get Form's hidden variable via Request object, sometimes we get them correctly but sometimes they are blank. Generally, first or second time, they show some values but after that they go blank. This problem is seen in IE 7 only and has not been observed in any other version of IE or other browsers.

From the master page of my ASP.NET site I need to set the value of a hidden field in every get and post request and then subsequently read it in the next request.The problem is that in the post request the code works fine but when the client sends a get request I am unable to read the value of the hidden field from teh Master Page. Is the hidden field the proper approach to this and if so how do I read the value set in the hidden field in the subsequent get request. If the hidden field is not the proper approach for this then what else should I use?
