I have the following javascript. Problem is if I enter one row in the table "ingredients" but I am getting 2 rows in the resulting pass to controller action after seralising into my C# object. But the second object is null? I checked the javascript and the variable "cnt" is 1 not 2. Why would that be?
[code]
$("#Save").click(function () {
var title = $("#recipetitle").val();
var category = $("#category").val();
var preptime = $("#prepTime").val();
var preptimeperiod = $("#lstPrepTime").val();
var cooktime = $("#cookTime").val();
var cooktimeperiod = $("#lstCookTime").val();
var rating = $("#rating").val();
var method = $("#method").val();
var jsontext = '{ "RecipeTitle": "' + title + '",';
jsontext += '"CategoryID":' + category + ',';
jsontext += '"PrepTime":' + preptime + ',';
jsontext += '"PrepTimePeriod":"' + preptimeperiod + '",';
jsontext += '"CookTime":' + cooktime + ',';
jsontext += '"CookTimePeriod":"' + cooktimeperiod + '",';
jsontext += '"Rating":' + rating + ',';
jsontext += '"Method":"' + method + '",';....................
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?
I have some textboxes and a table of data created client side that I want pass to a controller as JSON.
I want to use Jquery to enumerate the table.
Assume I have 2 textboxes called name and age. Assume a table with 2 columns. one column with class called phonetype and one column class called phonenumber.
I have asp.net mvc application. i want to configure the object in jquery and want to pass it to the the action of controller . where as in my script i am using this for configure data for the ajax call:
[Code]....
it does not calls to action in controller. i think here :
var json = $.toJSON(peform);
is not working as expect. is it need to add any js file to reference ? or mistake in syntax?
I have 2 classes that are used to mirror the data from an ajax call. One (Customer) contains a property which is name, and the other is an array of Products.
Public Class Customer Private _Name as String Private _Products as Product() Public Property Name() As String
I am trying to send json data from view to controller action. But the issue is the data is not populating in the action parameter List<Score>.
View Model: public class Score { public int QuestionId { get; set; } public int PrevAnswerId { get; set; } public int CurrAnswerId { get; set; } public string CurrAnswerName { get; set; } }
Json Data look like: [ {QuestionId:1, PrevAnswerId:3, CurrAnswerId:3, CurrAnswerName:'Known to Broker'}, {QuestionId:2, PrevAnswerId:7, CurrAnswerId:7, CurrAnswerName:'Completed'}, {QuestionId:3, PrevAnswerId:10, CurrAnswerId:10, CurrAnswerName:'Report'} ]
On window load, I will construct the Json object using "eval()" function and do some operation in the data before its save. On Save Click, I will call the action through the ajax call.
Action: public ActionResult SaveScore(List<Score> score) { // do something... }
But here score comming as collection of 3 elements with zero(for interger property)/null(for string property) values. When I checked in the request I found the data in "parama" property like.
But I am not sure why it is not getting populated in the score list. One full day I spent for this issue but till now I didnt find the solution for this issue.
I have the following to get the Json abject passed from the controller and populate the various textboxes in the view. However, nothing is happening even though controller is passing a valid Json object. What is wrong with this code?
<script language="javascript" type="text/javascript"> $(document).ready(function() { var url = '<%=Url.Action("DropDownChange") %>'; $("#vendorID").change(function() { var selectedID = $(this).val(); if (selectedID != "New Vendor Id") { //$.post('Url.Action("DropDownChange","Refunds")', function(result) { $.post(url, { dropdownValue: selectedID }, function(result) { alert(selectedID); $("#name").val(result.Name); $("#city").val(result.City); $("#contact").val(result.Contact); $("#address2").val(result.Address2); $("#address1").val(result.Address1); $("#state").val(result.State); $("#zip").val(result.Zip); }); } }); }); This is the code in my controller; public JsonResult DropDownChange(string dropdownValue) // This action method gets called via an ajax request { if (dropdownValue != null && Request.IsAjaxRequest() == true) { paymentApplicationRefund = cPaymentRepository.PayableEntity(dropdownValue); paymentApplicationRefund.Address1.Trim(); paymentApplicationRefund.Address2.Trim(); paymentApplicationRefund.Name.Trim(); paymentApplicationRefund.City.Trim(); paymentApplicationRefund.Contact.Trim(); paymentApplicationRefund.State.Trim(); paymentApplicationRefund.Zip.Trim(); return Json(paymentApplicationRefund,"application/json"); } else { return null; } }
Basically, I have an HTML Form and would want to pass the data from the form to n asp.net mvc controller, then the controller would return an XML for client side manipulation.
Here is my initial code:
[Code]....
When I run and debug, I get a message that says "attr(..) is null or not an object. I am still trying to learn web development using ASP.NET MVC.
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?
I have a User entity and a department entity. I have a UserViewModel and DepartmentListModel which has List of departments.
UserViewModel has a property of type DepartmentListModel .
Now on user/create action I need to populate DepartmentListModel by calling DepartmentController's list action. List action returns populated DepartmentListViewModel.
From UserController how do I set DepartmentListModel ?
I use the JavaScriptSerializer class of ASP.net to serialize my object and return it to the client side. How can I deserialize the string using JavaScript?
Also on the page I have a link that goes to another view to add an assistant for the application. I want to pass it the application ID so that the new assistant can be "linked" to this application. How would I get the value of 1 and add it to my action link? This is what I have in my HTML so far:
<%: Html.ActionLink("Add New Assistant", "Create", "Assistant", new { applicationID = "id" }, null) %>
If I have a controller with more than one action on, e.g. UserController, then I end up having that class require every dependency of every action. Is there a way I can have one controller per action and yet have the URLs appear the same way they currently do? e.g.MySite.com/User/Edit/1 would remap to User_EditController.Edit
I originally have the question posted here, but I need as many eyes as possible on it.Essentially, I'm having issues redirecting to an action in mvc2 when working with JSON data. I post a stringified JSON object to an action and the action in turn redirects as needed. It worked previously when using form fields, but not when I'm posting JSON. To get posted JSON objects to properly bind to parameters objects in MVC, I'm taking advantage of the JsonValueProviderFactory class from MVC2Futures/MVC3Beta.Why is this occuring? The jQuery ajax call is telling the server "I'm giving you json, I expect html in return" and all actions pointed to via RedirectToAction calls are structured in a similar manner. I instead get stuck in a loop, continually hitting the originally requested action, with a prompt to reenter authorization information to boot! It seems lose authentication/authorization information in the process.The linked question on
I am not sure what is going on but even though I am invoking a different controller with action a particular FooController's Index action is being invoked all the time. The Global.asax file has setup the FooController to be the default controller.
public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "FooController", action = "SomeAction", id = UrlParameter.Optional } // Parameter defaults ); }
I know I can create an aspx and perform redirect in it`s page load. But seems ugly and I think it can be done with some custom route.What I`ve tried was: this solution.but it didnt work for me. I remember, that Test.aspx should not be on a disk. I don`t have it, and routing is still not working.
In ASP.NET MVC 2, to secure controller action, i have created a class RequirePermission inherited from ActionFilterAttribute class. The controller action looks like
[Code]....
Now instead of making different attributes , I want to use RequirePermission attribute like [RequirePermission(permissions=Permissions.CanView+","+Permissions.CanEdit)] so that i can use it for different scenerious. but the compiler throw the following error. An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type
I know I can use Html.ActionLink(...) from my view to render an anchor tag with a link to an action. I know I can call RedirectToAction(...) from the controller to immediately call another action. But what I'd like to do (and don't know how), is get an action link from within the controller. I am building up a breadcrumb and want the link to an action. So I don't want to immediately jump to the action (as with RedirectToAction), but just get what the link would be.
I am calling a Controller Action from a view, within that controller I need to invoke another Action which I will invoke to save the view to a network location as either HTML or Image.
How do I retrieve the URL to an Action from within a Controller. I need the actual URL, this means RedirectionToAction or View() wont work.
Why? I need to pass in a URL which will contain a call to a View. This view will be used to generate an image or HTML document using the System.Windows.Forms.WebBrowser.
.NET 3.5; C#; MVC 1;
I could do something like this, but its dirty ... well it leaves me with that dirty feeling.
I would like all actions of a controller to read some master page level values from the querystring and write those values to ViewState. How do I do this in ASP.NET MVC?
What's the correct way to get the controller name and action from an httpContext object? I can see the values in the debug, but I don't seem to be able to get to them in the object code?
