My method looks like:
public static RedirectToResult(Controller controller, ...)
{
}
when I do:
controller.
I don't see RedirectToAction, how come?
I get RedirectToAction from within the controller's action, but not when I pass the controller as a parameter to another classes method.
I want to pass a int value using RedirectToAction() method .
Here i have a Action method Index() which takes 1 parameter id in most of the cases this id cannot be null.
When i submit the form using Action method Edit(), i want to come again on Index page,so i am using method RedirectToAction("Index")
but here with Action Name i want to pass the id also. How can i do it?
public ActionResult RenderMyThing(IList<String> strings)
{
return View("RenderMyView");
}
How do I pass in strings?
routes.MapRoute("MyRoute", "RenderMyThing.aspx", new { controller = "My", action = "RenderMyThing" });
Is there a way I could pass in strings here?
Secondly, how does ASP.NET MVC know that action is my action, and controller is my controller. Like I saw this in samples, and it does work, but isn't it just an anonymous object with no type?
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've been using MVC since the previews of 1.0 and I think I know what I'm doing, but for the life of me I can not figure out why sometimes when I use RedirectToAction it crashes saying there is no route available. Consider this in MVC 2.0:
I'm registering on my site and I first hit the SiteController, which does its magic then I am to be redirected to my new dashboard, controlled by the... DashboardController. I never make it there. I specify the action and the controller in the redirect call, but it still crashes and burns. The only thing I can possible think of is because the DashboardController is its own area, but that still doesn't help me because by my understanding it should still work regardless.
I am new to MVC2 and have hit a wall. When I use an action link to jump back to a previous page that I have already been on, my controller is not called but the page is rendered correctly. Is this some sort of caching that I am not aware of? This also happens with a RedirectToAction call from another Controller. rfm is the Model...
return RedirectToAction("Search", rfm);
Here is the actionlink...
<%: Html.ActionLink("Search", "Search", "Reference")%>
input type=..... value="<%= ISO3166CountryList.GetCountryByCode("IE", CurrentLocale).Name %>" />
I'm looking to replace the hardcoded IE with something like
<%#(Container.DataItem as PhoneNumber).ISO%>
No variations of what I've tried worked. How can I get a databinded value when within a <%= code block? Do I need to use an intermediary variable?
I have the following ActionResult() method:
[Code]....
The method is called once the <form> is submitted. If the validation is good, it moves on to create a new user Once the new user is created, I want to redirect the user to a "ThankYou" page passing along the newly created user (object). The TempData["User"] trick seems to work like a charm! Then inside my ThankYou ActionResult() I do the following:
[Code]....
The problem I have is once the user has been redirected to the "ThankYou" page. If he decides to refresh (F5) his browser, the value in the TempData is lost.
What are my possibilities to overcome this issue?
Instead of passing an entire object to my "ThankYou" page, I initially thought of passing the ID of the newly created user and re-query my database to get the object.
The only problem is that the ID will be seen in the QueryString allowing the user to simply change the ID value and try to find other users...
Is my only other alternative to simply place the user object inside a Session? Is that my only other option?

View 5 RepliesI 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 am getting an null referance on file, what am I doing wrong.

I have setup an httppost that sends a string into my controller, searches for some results using linq, and then sends the results to a view. In debug stepping through the code I can see the data that I am looking for being passed into the return view statement, but the page just appears to refresh (it doesn't render the view as expected with the result). why my controller fails to redender the view? (note: I didn't include the view because I can send a ToList() to it without an issue. For example, return View(_entities.Persons.ToList());
[HttpPost]
public ActionResult RenderSearch(string usersearchtext)
{
if (usersearchtext != null)
{
var search_results = from s in _entities.Persons
where s.Description.Contains(usersearchtext)
select s;
return View("SearchResult", search_results.ToList());
}
else
{
throw new NotImplementedException();
}
}
I would like to pass List<SelectListItem> (not selected item but the whole "List" object) back to controller.
for example in my GET controller i would have this
ViewData["list"] = some select list from repository;
then on post I would like to get the list back from view..pretty much i'm trying to use ViewData["list"] as storage..this way I would use ajax to remove or add items to/from the list.

I am new to MVC, and trying something and got stuck somewhere in between.I have a user control there I have three textbox html type(ID, Lastname, firstname) and a submit buttom. I set the button like
<input type="button" value="Search"
onclick="location.href='<%= Url.Action("action", "controller") %>'" />
I have called this usercontrol on some view through
<%= Html.Partial("ucName") %>
Now on pressing that button(on user control) I need to pass the data from these textboxes to controller again to some specific action(Http Post action). By using this data I want to do some database interaction and storing the result in a dataset and pass this data set to same view again to show up in some Grid.I know the first part in conventional Asp.net can be done by raising the event through delegate but don't know how to do that in MVC.
I have a dictionary I'm passing to a View. I want to be able to pass the values of that dictionary back to a Controller action from this same View. Is there anyway this can be accomplished without using a form? The situation is that I need to be able to pass these back to a controller action that is called when a user clicks an ActionLink from the View, and in my experience an ActionLink cannot be used to submit a values of a form, i.e. I've only been able to submit values of a form using the form's submit button. Unless there's a way to use an ActionLink to submit values in a form.Controller Action passes Dictionary to Controller in ViewData:
public ActionResult ModifyNewCrossListing(FormCollection form)
{
Dictionary<int, string> prefixlist = new Dictionary<int, String>();

I have the following scenario: my website displays articles (inputted by an admin. like a blog).So to view an article, the user is referred to Home/Articles/{article ID}.However, the user selects which article to view from within the Articles.aspx view itself, using a jsTree list.So I what I need to do is to be able to differentiate between two cases: the user is accessing a specific article, or he is simply trying to access the "main" articles page. I tried setting the "Articles" controller parameter as optional (int? id), but then I am having problems "using" the id value inside the controller.

View 4 RepliesI have following situation - I am pasing user info object from Controller to View. It contains GUID UserID, which i dont want to be seen on page. So I removed every Html.LabelFor(model => model.UserID), Html.TextBoxFor(model => model.UserID) etc... from generated View source. And because of this when Html.BeginForm() returns that object back to Controller all values is there but UserID is lost??
If I leave Html.LabelFor(model => model.UserID), Html.TextBoxFor(model => model.UserID) etc.. in View everything is fine. But I dont want to show UserID? Where is the problem here?

I've been going at this for several hours and I simply cannot find the solution.
I want to get some data from my user. So first, I use a controller to create a view which receives a Model:
[code]...
The rest of this controller does not matter since no matter what I do, the count attribute of Request.Files (or Request.Files.Keys) remains 0. I simply can't find a way to pass the files from the form (the Model passes just fine).
I'm having problems passing values from the controller to the view. I created a boolean variable to use as a flag and want the view to render some html based on whether its true or false.
Unfortunately ViewData doesn't look like it can pass boolean values. I should be able to pass any datatype to a view (string, int, bool, etc...)
