MVC :: Passing Of Id To Edit Action
Mar 30, 2010I am rather new to ASP.NET MVC and am trying to develop good practices and have studied a few tutorials and videos. There seems to be some differences in how people define the signature of a typical edit action method - sometimes the id (primary key) is listed and sometimes not. It seems like letting the framework do the model binding is a GOOD THING, so I will probably have the model (or view model) as a parameter:
ActionResult Edit(int id,
CompanyViewModel company);
ActionResult Edit(CompanyViewModel company);
But, should the id be a parameter too? I assume it is common-place to have the id in a hidden form field as well so the id (primary key) is then already bound in the model (or view model) - if so, what is the id parameter good for? Or should it be the other way around - keep the id parameter and do not bother using a hidden field for it? What are the pros and cons and what is the best practice?
MVC :: Passing A Checkbox Value Via An Action Link?
Jan 12, 2011I have an action link that I use to pass values to a controller using this statement:
<%: Html.ActionLink("Addition 1 to 10", "CreatePdf", "Pdf", new { id = 32, stOperation = "Add", stNumbers = "10" }, null)%>
So when a user clicks on the above link the controller CreatePDF is called with the parameters of id, stOperation, and stNumbers. I then use these three parameters to return a pdf document to the user.I also have a checkbox on the html page as defined by:
<%: Html.CheckBox("chkAnswers", false) %>
My question is how to pass the value of this checkbox in the above HTML.ActionLink? I have a tutorial on using the submit button to submit an entire form and the associated data. However I do not want the user to have to click a button. Instead I'd like return the value of the checkbox in the action link but I'm not sure how to do this. I want something like:
%: Html.ActionLink("Addition 1 to 10", "CreatePdf", "Pdf", new { id = 32, stOperation = "Add", stNumbers = "10", checkboxValue = true or false }, null)%>
Passing A Parameter To Action Method?
Sep 8, 2010public 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?

Javascript - Passing JSON To Controller Action
Mar 7, 2011I 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?

MVC :: Passing Json Collection Object From View To Action
Nov 1, 2010I 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.
$.ajax({
url: url,
type: "GET",
dataType: 'json',
data: {score: ScoreJson},
contentType: "application/json; charset=utf-8",
success: function () {
alert("succes");
},
error: function () {
alert("error...");
} });
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.
"Score%5b0%5d%5bQuestionId%5d=1 &Score%5b0%5d%5bPrevAnswerId%5d=3 &Score%5b0%5d%5bCurrAnswerId%5d=3 &Score%5b0%5d%5bCurrAnswerName%5d=Known+to+broker&
Score%5b1%5d%5bQuestionId%5d=2 &Score%5b1%5d%5bPrevAnswerId%5d=7 &Score%5b1%5d%5bCurrAnswerId%5d=7 &Score%5b1%5d%5bCurrAnswerName%5d=Completed&
Score%5b2%5d%5bQuestionId%5d=3 &Score%5b2%5d%5bPrevAnswerId%5d=10 &Score%5b2%5d%5bCurrAnswerId%5d=10 &Score%5b2%5d%5bCurrAnswerName%5d=Travelers+Report&".
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.

The Long:I am using ASP.NET MVC 1.0 framework. I have a "RequireSSL" actionFilter that I've recreated for checking out, however, if someone leaves the checkout and goes back to the store I would like to forward them back to non-secure version of the site.It would be helpful in the base controller (I am using a custom base controller that inherits from the default Controller) to find out what actionFilters are being applied to the current action.I could include this into the global.asax.cs
MVC :: Posting List Of Checked Items To Controller Action Using JQuery Post?

MVC :: Passing A List As A Parameter With BeginForm()?
Mar 2, 2011I am using HTML.BeginForm to create a form on my page. I need to pass a list of classes I created as a parameter. It's done like this:
<%
using ( Html.BeginForm("DisplayCompanions", "CCDReviewController", new { CompanionList = Model.CompanionList} ) )
{ %>
When I click a "Continue" button (enclosed in the form tag), the "DisplayCompanions" method on my Controller ("CCDReviewController") should be called, as I've set a breakpoint on it. But it's not being called.
Note that Model.CompanionList is a generic list of classes that I created.

Web Service - Passing A Base Object With List / Collection?
Apr 9, 2010We need to create a simple web service in ASP.NET that can be called from PHP or other languages. This in turn will be used to update records in a database for an item submission.
The core part is fairly simple, we have a base set of fields for the object - first name, last name, birth date, city, etc. In addition however we need to accept a list of items associated with that object that can range from 0-n.

What would be the best way to structure this so it can be easily passed to the ASP.NET web service and processed as a single call for the entire object? Would passing the list of items as a single delimted string be a wise approach? Ex: Jan 1 2009, ABC|May 1 2010, 123|Jun 30 2010, XXXXX
