MVC :: Redirecting To Same Action Without Parameters?

Jul 27, 2009

I've got a route like this:

Event.aspx/Register/123

Which is for registering for event ID 123.

I would like, when someone comes in on a URL like this, to immediately redirect them back to a URL like this:

Event.aspx/Register

I will store the event ID in session, so I still know what event they are registering for.

Here's what I tried:

[Code]....

But I wind up in an endless loop, it always redirects *with* the ID parameter, which in turn triggers another redirect, but again, the redirect goes to Event.aspx/Register/123... so I'm caught in a loop.

By the way, I'm on IIS 6 and I'm using the .aspx extension on the controller name as the easiest way to get the routes working. It's worked just fine so far--no problems--other than this redirection issue...

How do I get this working? By the way, I tried this.RedirectToAction("Register") but that didn't work either.

How To Pass Parameters To An Action Using Html.Action() In MVC?

Jun 30, 2010

I've been using Html.Action("ActionName", "ControllerName") to invoke child actions across controllers without needing to have the view in ViewsShared. This has been working great for displaying things like session or cookie information.

Instead of just accessing cookies, I would like to pass additional parameters to Html.Action("ActionName", "ControllerName") so the action can execute different code based on the the data passed to the original view.

Should I be using a different method to pass parameters to a child action in a different controller?

MVC :: Optional Controller Action Parameters?

Dec 11, 2009

I have lots of action methods that have a Paging object parameter. e.g.

ActionResult Search(string query, Paging paging); and have registered a paging model binder. If the pageSize and pageIndex don't exist, paging goes to the default.

I'd like T4MVC to somehow skip this particular parameter if possible in the helper method generation, so I could simply generate a URL using

Url.Action(MVC.Home.Search("donuts")).

Currently, it's either all or no parameters.

How can I mark the paging parameter so that's optionally skipped from the T4MVC generation?

Web Forms :: Client Side Form In Masterpage Not Redirecting To Value In "action=" Field?

Nov 4, 2009

I am not getting a page redirect when this form is submitted and I am not sure why I am getting this behavior.Here's my form markup:

[Code]....

The hidden input types are used with the google custom search that is wired to this form. This code is in my masterpage. The masterpage also has the server side form that wraps the whole page so I had to render this one as a client side (because I can't hide visibility of the main form..I think)I am supposed to be redirected to searchresults.aspx and google uses JS to pass back search results into a specified div on the searchresults.aspx page. This behavior was working for me before I converted this website to use ASP.net.Can someone clue me in on what I have done wrong? Every time I submit the form it just posts back to itself instead of redirecting. I tried both method="post" and "get" and nothing :(

MVC :: How To Pass Values To Action Methods Without Parameters

Jan 20, 2010

Is there any possibility to pass values of form elements to action methods but using parameters?I have a form with a lot of input fields and the method signature will get pretty long. Besides the form elements depend on each other so if the user makes a special choice only a subset of the form elements should be displayed so there are several combinationof values to be passed.Can I access the posted values in a generic way through a collection in the controller or something similar?

MVC :: Routing Is Correct, But Parameters Don't Reach The Action Method.

Jul 1, 2010

I've been struggling for some time now with an MVC routing issue, but I have finally reached a point where the basic routing is correct; that is, the application is invoking the correct action method and .aspx page, but the action method fails because no parameters are passed to it.

Before I show detailed screenshots of the problem, I had better provide some background. This is a bibliographic application which, among other things, analyzes text abstracts to identify unique words and the number of occurrences for each word in each document. This data will eventually be inserted into a SQL Server database, but for the time being I only want to do the calculation and display the results, on a document-by-document basis, in an .ASPX view set up for the purpose. The data structure of the application is as follows:

Collections -this is a set of fifty or so CollectionDetails items.CollectionDetails represent individual documents, in this case books in an academic library. Attributes of the CollectionDetail record are those typical of a library book--author, call number, title, year, and so on. The title and subject catalog headings are combined to form a quasi-abstract, which becomes the basis of the text analysis. In a few cases, I added additional text from Google Books or Amazon synopses and reviews.

MasterStopList contains common words such as pronouns and prepositions that we want to exclude from consideration.

Calling Action Method In MVC With JQuery And Parameters Not Working

Dec 27, 2010

I'm trying to call an action method in an MVC application using jQuery. Basically what I want is to take the value of a couple of input fields and call the action method by clicking a button, passing the values of the input fields as parameters. But I only get the value of the "number" parameter, not the "year" parameter.

function selectWeek() {
$('#selectWeekButton').click(function (event) {
var number = $("#selectWeekId").val();
[code]...

I checked the url with an alert, as you can see, and it seems to contain both values fine. But when I check the value of the year parameter in the action method it is null.Here are the input fields:

<span>Vecka: </span>
<input type="text" id="selectWeekId" />
<span>År: </span>
<input type="text" id="selectYearId" />
<input type="button" value="Välj vecka" id="selectWeekButton" />

And the beginning of the action method:

public ActionResult Edit(string number, string year)
//etc...

I know that this looks like a strange thing to do instead of just binding fields, but the reason is that these input fields and their values is not the main purpose of this View. They're just there to select another week in this timesheet application. And besides, I'm going to replace the input fields with a jQuery calendar eventually, so I will still have to do something like this.

So what's the easiest way to do this, and why isn't it working as it is?

MVC Action Parameters With Binded Prefix Not Compatible With Url.Route In Global.asax?

Nov 17, 2010

I have a details page containing a form field named UserId. On the same page i have another search form with a field also named UserId.

I am using Html.LabelFor(vm > vm.UserId) and Html.TextBoxFor(sm > sm.UserId) on the two different view models, vm being the view model and sm being the search model. (Yes, the UserId property on the two models has identical names - because they are the same domain property.

When i navigate to the page, the populated UserId on the vm is inserted into BOTH form fields named UserId by MVC. Even the sm.UserId are empty.

That is my initial problem. There are a few ways ti avoid that. My solution was to use the Prefix flag for the sm.

[code]...

My problem is that MVC can't map the Search.UserId (because of the .) to fit the UserId (prefixed with Search) in the action shown above.

So it seems like MVC has a prefix-feature, that are actually nok fully supported through the Route-handler.

Ofcourse i could rename the Search.UserId to Search_UserId, but then the name dosent match the name MVC expects in the recieving action above. (expects Search.UserId) Renaming The UserId property of the search model would fix the issue, but since it is the same value in the domain, this seems like a workaround.

MVC :: Nullable DateTime Action Parameters Parsed In US Format Irrespective Of Locale

Aug 20, 2009

Hi There,



I have a fairly large MVC Project I have been working with for some time. Suprisingly I have only just created an action with nullable date time parameters, IE:

public ActionResult MyAction(DateTime? startDate, DateTime? endDate)

Now when I pass a date formatted for the UK these parameters are NOT populated. When the date is formatted for the US they are.If I pass a UK formatted date that is compatible with the US format the parameter is populated but the month/day are switched round.

In the UK and most of Europe dates are listed Day/Month/Year. IE: 20th Aug 2009 is 20/08/2009 NOT 08/20/2009 as it is un the US.

So:

.../MyAction?startDate=01/01/2009 Works and I get first of Jan 2009.

.../MyAction?startDate=13/01/2009 Fails - start date parameter is empty.

.../MyAction?startDate=05/01/2009

Fails - start date parameter is populated but with 1st May 2009, when it should be 5th Jan 2009.

It's pretty easy to guess what is happening here. For some reason the ASP.NET MVC framework is not picking up the locale when attempting to parse the date. Is this a known bug? If so is there a planned fix?

I have got round this for now by hacking the action so the dates are string parameters that I then parse myself...

MVC :: "Action Methods Cannot Have Unbounded Generic Type Parameters." Mean?

Sep 28, 2009

What does this mean?Action methods cannot have unbounded generic type parameters. An unbounded generic type parameter has an empty parameter list. An unbounded generic type is also known as an open generic type. For information about unbounded generic type parameters, see the section "Unbounded Type Parameters" in Constraints on Type Parameters (C# Programming Guide).It is written here: Controller Class I understand it in a way, that it is possible to use a generic type as an action parameter, as long as it is restricted with "where". Like explained here: Constraints on Type Parameters (C# Programming Guide) There it is written:

Type parameters that have no constraints, such as T in public class SampleClass{}, are called unbounded type parameters.It would follow that if T had constraints, it would be allowed. However in the first source it is written:

An unbounded generic type parameter has an empty parameter list.This sounds like as if it was not allowed to have any generic type in the parameterlist, that is not bound to a concrete type. Is or is it not possible to use generic typed parameters in actions?

MVC :: Why Synchronous Action Wasn't Executed Until Asynchronous Action Completed

Nov 29, 2010

I'm implement Comet in Asp.net MVC, I used timer to keep Async request in server, Async request will complete when timer elapsed 1 minute and response to client (to avoid 404 error) and then reconnect to Async Controller. I also wanna execute some Synchronous action during Async request was holding, but the problem is: When an Async action was executed and hold by using timer, the Sync Action wasn't called until Async action (comet long-live request) completed. I did test with firefox 3.6 many times, but the result is the same, so strange, Do you know why ? I have a sub some questions : To implement comet, using timer (response after some minutes elapsed) or thread (response after several time sleeping thread) to hold async request, which is better?

MVC :: Helper And Action And Google Controller, GoogleController, With An Action Adsense?

Aug 27, 2009

I need to display a Google AdSense Ad in a few views of my application.

Basically the ad is created by rendering some javascript code that needs 4 parameters:

String client, Int16 height, String slot, Int16 width

I know the following options:

1) Pass the parameters in the View Models in all views that has an Ad and display it using a Html Helper:

[Code]....
2)Have a Google controller, GoogleController, with an action Adsense that would return the view AdSense with the javascript code.Then on each view I could render this action.I could also have GoogleViewModel to pass the parameters values and have something like:

[Code]....

Will I need to create a Route in my Global file to be able to use these parameters as inputs of the action?

3)I could have 1 and 2 together:

On each view I would call the action Google/Adsense This action would have the parameters Slot, Height and Width Then it would pass those values together with the Pub definined inside the action because for a web site the account client would be the same.the AdSense view would use the Google Adsense helper to render the code because this way I could use this helper across different projects.

How To Get The Individual Parameters From The List Of Dynamic Parameters In A Webmethod

data:JSON.stringify({fname:firstname,lname:lastname,city:city})

now my requirement has been changed such that,the number and type of parameters that are going to be passed is not fixed for ex.parameter combination can be something like fname,city or fname,city or city,lname or fname,lname,city or something else.So the webmethod should be such that it should accept any number parameters.I thought of using arrays to do so, as described here.

But I do not understand how can I identify which and how many parameters have been passedto the webmethod to insert/update the data to the DB.
