MVC :: How To Reference A Hidden Input Control's String Value In Controller Action Method
Jun 3, 2010
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?
I am having a dropdown server control on view, when the user clicks the submit btn at that time the form gets posted. and a action method in view controller is called with verb=post.
But the problem is that how should i get reference to the dropdown server control in the action method of view controller?
I'm just starting to use the TestHelpers in MvcContrib. I want to try and test an action method on my controller that itself tests if IsAjaxRequest() is true. I've used the same code that is shown in the TestHelper samples to set up the TestControllerBuilder
_controller = new StarsController(); _builder = new TestControllerBuilder(); _builder.InitializeController(_controller);
So that _controller has all the faked/mocked HttpContext inside it, which is really great. But what do I do now to force IsAjaxRequest() on the internally faked Request object to return true?
When I use editurl property in my jqgrid, the controller action gets called after I hit submit button on adding a new row. But how do I get all the grid rows there? Which parameter should I read from my controller action method in order to get the grid data?
I am trying to get this functionality on my jokes website:
www.mysite.com/category/bar
To get all the bar jokes ..etc
The way I have my route right now is:
{controller}/{action}/{id}
which means I have to type:
www.mysite.com/category/index/bar
the problem is that even with that, the string parameter "bar" isn't being acknowledged ! ( I know from debugging). Here is my Index action in the Category controller:
I am creating one Json array object and trying to pass it in MVC controller action method but i am getting null paramerter; as per my knowledge json only maps .net primitive datatypes.... so it assign null value.
Note: when i have look at request object i found that there are three parameter of created array. But how to get that value as parameter of function?
Assume the current executing action method is Index() in Home controller. From within Index(), how to obtain the physical file path of the Home controller? Assume we don't know the file structure until runtime.
In an ASP.NET MVC 2 application, how would I obtain the Type of the controller that would be used, given the information about the route: string action, string controller, object routeValues?
(The routeValues object might look like this new {area="admin"} and route to a controller for a different site area.)
How can i transfer control to a controller's method from a controller's method..I am having two Controllers Home and User..

I am creating my first MVC application.I have a View named "Product".I want to use two asp.net control MENU and MULTIVIEW and on OnMenuItemClick event of MENU I want to select the View of MULTIVIEW. Please tell me how can I process asp.net control event in a MVC application.Can we mapp control event to Controller Action.
I'm creating an ASP.NET MVC 2 (RTM) project that uses areas. The Index action of the Home controller of one area needs to use RenderAction to generate a sub-section of the page. The action called is also defined in the same Home controller. So the call should just be:
<% Html.RenderAction("List") %>
However, I get an exception:A public action method 'List' was not found on controller 'RareBridge.Web.Areas.Events.Controllers.HomeController'.
Note that I'm not in the "Events" area! I'm in a completely different area. If I remove the "Events" home controller, then the exception still occurs but names a different controller (still not the one I want it to call).
I've also tried providing the controller name and area to the RenderAction method, but the same exception occurs. What is going on here?

Is there a way to control when a data annotations validation is performed based on the actionmethod that you are in? For instance I have a model that I have decorated with a custom validation attribute that checks to see that at least on of three properties has a value. The current view does not contain a way for the user to assign a value to those properties the next view in the workflow does. When I submit the first view and check that the model state is valid I am returned false since the three fields that should be filled on the next view have not been assigned a value, and I get stuck on the first view in the process.
Lets say I have a simple controller for ASP.NET MVC I want to test. I want to test that a controller action (Foo, in this case) simply returns a link to another action (Bar, in this case).How would you test TestController.Foo? (either the first or second link)
My implementation has the same link twice. One passes the url throw ViewData[]. This seems more testable to me, as I can check the ViewData collection returned from Foo(). Even this way though, I don't know how to validate the url itself without making dependencies on routing.The controller:
public class TestController : Controller { public ActionResult Foo()[code].....
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?
