MVC :: Retrieve Javascript Values Back In The Controller?
Mar 17, 2011
may I ask one seemingly simple question - I have a Javascript function that loops through my checkboxes(they're plain HTML checkboxes, not using the helper methods), and for every checked one it's adding its value to an array. So now, how do I get this array in my controller so that I can assign its values to the fields, i.e. object's properties?
This is my checkbox code:
[Code]....
and the script:
[Code]....
and here's the controller code:
[Code]....
Now, this langID should be assigned every checked checkbox's value, so I guess I'm missing a loop here too, it should go until some border that's gotten from the client script or something, but my bigger problem is how to retrieve the posted values from the javascript, something like PHP's POST["array"]...?
This Request.Form works fine when just one checkbox is checked, but now I need it to work with several checked..

I am having a form in a view page that looks as below:
[Code]...
Now when the form is posted, I am trying to retrieve the values submitted in the controller as below:
[Code]...
The string value shows null when I submit the form by checking some checkboxes. Is this the way to retrieve the values or am I doing something wrong? And I cannot use html control because all other controls on the form are server controls and I am not sure if I can only make this control a html control. And I am not sure how can I bind the values to it?

Currently, I am working with ASP.NET MVC1 and am still learning about Model Binding and how values from a View are passed back to the Controller / Model. Specifically, I want take an existing Model, create a Table and populate the Rows of the Table, allow the user to edit some fields and pass it back. In my example, I have a Class called "Ingredient" which has 4 public accessories: Name, Barcode, Amount, and Unit.
[Code]....
Or is this not possible? (Basically, I'm trying to re-create a datagrid where certain fields are editable and certain are not...)

I've created 3 buttons, first button is to load the values in textboxes added to placeholder. Then button2 is to extract the data from button 1 and display out. Now the 3rd step, I want to edit the values from the textboxes, after edit, how do I grab and display out the new values in label and textboxes?
Code:
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim x As Integer = 1
Dim message As String
[code]....

I 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 use a ModalpopupExtender to show a dialog to the user which consist of a CheckBoxList control that is bound to a session table. The user can check/uncheck the CheckBoxList items and click the Ok control to close the ModalPopUp. How can I retrieve the values of the CheckBoxList items controls using JavaScript (seems like I cannot do it using server side scripting)?

I have a filter on my MVC web site. I display some records in a few different controller actions but when moving from one action to another I want to apply those filter values.
How can I persist values from controller to controller?
Should I use Session? TempData?
I am using Structure Map for IOC.
Maybe I could have a class that contains a Property for each Session Value that I use in my application and inject it on the controllers that need session?

Being new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

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.
using(Html.BeginForm("Action", "MyWorkflowController",
new {
MyId = "bla",
URLToGenerateImage = Url.Action("GenerateImage", "MyWorkflowController")
}))

I know I can use method this.RediectToAction("Index", "Home") to do it but I don't want to method. It will fail to redirect when view or controller renamed.

This may seem simple to a seasoned coder, but I'm all wet-eared and new to MVC, and trying to wrap my head around it is driving me nuts. I have completed the Nerd Dinner and MVC Music Store tutorials, and seem to be grasping the basics... Well, sort of... It just seems that every new idea I have requires hours of searching with Google.
As it stands at the moment, I have a static DateTime field that is populated by using DateTime.Now. What I need to implement is a master TextBox (JQueryUI DatePicker) at the top of the View that will enable the user to overwrite said DateTime.Now if required.
Here is a hypothetical situation:
Controller
[Code]....
Site.Master
[Code]....
View
[Code]....
I thought of using a variable to override the default date if the user selects a master date, but can't figure out how to implement it.
I can get it to work if I use a static string, like so:
[Code]....
Is there any way to pass the value of the master datepicker (txtDateTime) from the View back to the Controller? I've heard mention of TempData, but can't seem to find a similar scenario.
I'm sure I'm just missing something really obvious, so if anyone could explain it to me really s-l-o-w-l-y, that would be cool.
I'm praying that this isn't another of those situations where "MVC doesn't work that way" or "It needs more cowbell", 'cause then I'll pack it all in and go play WoW D:

I have been at this for hours and am pretty stuck. I am using MVC2 with VS2010 Beta 2.
Here is my javascript from the view:
[Code]....
Here is my controller code:
[Code]....
I can set a breakpoint in the GetMember method and it does receive the Member_ID parameter correctly. It also correctly returns a member object from my repository (dpR). The function in $.getJSON call that is supposed to receive this result does nothing however. There are no exceptions or javascript errors. It is just silently dying.

ASP.NET MVC 2 and the display of commonly used data.Let's say for example, I wanted to have a listing of "Latest News" items on the right hand of my web page. Back in the day, I would made a user control called NewsList.ascx, put some DB data retrieval code in the code-behind and drop the user control intoI would like to do the same thing, but using MVC. Obviously, I don't want to place DB retrieval code into every controller to retrieve news items for the ViewData.How could I add a "Plugin?" or similar to retrieve the data across EVERY controller?

I 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?
<%= Html.LabelFor(model => model.C__User_Id) %>

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).

ASP.NET Ajax Library provides some client-side events. For instance:
Sys.Application.add_load(
function(args) {
// handle the end of any asynchronous post-back. Every-time there's
// a server round-trip, this method will be called.
}
);
During the asynchronous post-back I want to retrieve information to the client. This information must be available in some event like the discribed above.
Does the UpdatePanel or the ScriptManager have any server-side way to retrieve data back to client during an asynchronous post-back?

What is the easiest way to save form data and retrieve it when the user navigates back to the page?
We have an application process that consists of several web forms. If the user clicks to go back a step we would like to auto-populate the fields. I am assuming there is a common generic way to do this without having to mess with individual controls - what is it?

I have an ASP.NET MVC2 application that supports visualization plug-ins/providers. The IVisualization interface is defined in a common assembly which is referenced by both the ASP.NET MVC2 app, and any visualization providers.
In the Visualization controller, I have a method which returns all the applicable visualizations for a given set of data. In order to scan the available providers, I use the following code in the controller's ActionMethod.
var catalog = new DirectoryCatalog(HttpRuntime.BinDirectory);
var container = new CompositionContainer(catalog);
var visualizations = container.GetExportedValues<IVisualization>();
However, I feel like if I have the following in the controller
[ImportMany] public IEnumerable<IVisualization> Visualizations { get; set; }
then the import should happen automatically. What am I missing that prevents the automatic imports?
Also, is the code that I am currently using going to kill scaling of website?
