C# - Pass Nested Lists From View To Controller Using Viewmodels?
Mar 24, 2011
I am Francesco and I am newbie. I have a problem with ASP.NET MVC3 regarding the data posted between View and Controller. My goal is to use a form to edit a specific record from my database and then post it back to the controller, which is in charge of checking the record's fields and submit them into the database.
The data are passed from the Controller to the View by using a ViewModel and therefore the DefaultDataBinding does not apply in this case. I tried many approaches, I monitored the communication with Fiddler but I couldn't solve my problem. The method described by Phil Haack does not work and neither does the FormCollection.
Here you have the code:
ViewModels: I pass it to the View to create a table. Name and the list of Item names (table columns headers) are just to be displayed. I want to have back the Id, the Month (they are passed correctly as parameters and represents table row headers) and most important the ActualValue of the Items and their Id (I have an association table in my database with Id, Itemid and Month as keys)
[Code]....
View: The View is strongly typed as ViewModels.EditViewModel and sends the fields through a submit button. I have to generate a table by using foreach loops, because I do not know how many items there are in advance
Controller: The controller has to update each kpi passed from the view related to a specific Id and Month.
[HttpPost]
public ActionResult EditMonth(int Id, int Month, //FormCollection kpiValues)

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?

So I have two nested view models, CreditCard -> BillAddress. I have a view, "EditBilling", that has EditorFor(CreditCard). The CreditCard EditorTemplate has EditorFor(BillAddress), and the BillAddress EditorTemplate has EditorFor(BillState).
The end result is a select list with id "CreditCard_BillAddress_BillState".
I need to reference this in javascript, thus need to know the ID. In other situations, with non-nested ViewModels, I have used the following code:
$('#<%= ViewData.ModelMetadata.PropertyName %>_BillState')
The problem here is that the ModelMetadata.PropertyName property is only aware of the current property, not the parent(s). So I end up with the following:
$('#BillAddress_BillState')
How does one go about getting the client ID of nested strongly typed helpers?

I want to pass a message from the controller to a view using Viewdata. Here is my code:
public ActionResult Create(FormCollection createPage)
{
try
{
......................
ViewData["Message"] = "Success - rec added!!!!" ;
return RedirectToAction("Index");
}
catch (Exception e)
{
ViewData["Message"] = "Exception: " + e.ToString();
return RedirectToAction("Index");
}
On my View I have:
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<h2>::><%: ViewData["Message"] %><::</h2>
<h3>==><%= ViewData["Message"] %><==</h3>
<p>
This is Index.aspx page in Controller folder
</p>
</asp:Content>
I am getting result with empty ViewData["Message"]

My view has a number of rows.
Each row has a drop down, a text box and an "add" link. I'd like for someone to select something in the drop down, edit something in the text box and pass that information to an Action in the Controller.
I know i can do something like this:

[Code]....
Which is kind of gross - id like to do just call one action, that passes the selected drop down value, the textbox value and call just the one action, is it possible to do something like this:

Where i pass the Dropdownlist selection and the textbox value to my controller specifically

For example, controller action:

if I use a Html.Hidden field in my view, when the value click to submit the form I would like to pass this data to the controller. This variable would contain int as key and string as value,
Dictionary<int, string> interestTable = new Dictionary<int, string>();
How can I specify the htmlAttribute fo this variable in my Html.Hidden code?
<% using(Html.BeginForm("Search", "SearchMembers")) { %>
<input type="hidden" name="ResearchInterests" id="researchInterests" value=""/>
<%= Html.Hidden("fullInterestsPath") %>,

I have a view which takes two objects: booking and list of reasons for canceling that booking.I have two classes: clsBooking, clsBookingCancelationReason I can read both objects in my view - no problems there. After I read the objects, I display the booking details and I generate a list of cancelation reasons in the following way:
[Code]....
The code above generates a list of cancelation reasons.How do I pick up the selected ReasonId from the list?
I need to generate a link that will contain the bookingId and the selected reason for canceling the booking.I can get the bookingId out easily since it's stored in the Model...but how do I go about the selected ReasonId?

I have a grid view with a nested text box in it.I would like to turn view state off but the fact of the matter is when data is posted,the text boxes inside the gridview aren't available (there are no rows in the gridview on postback). Control's information is not stored in the View State (for things like selected value and .text etc.):Control state,introduced in ASP.NET version 2.0, is similar to view state but functionally independent of view state.However,control state cannot be disabled. Control state is designed for storing a control's essential data (such as a pager control's page number) that must be available on postback to enable the control to function even when view state has been disabled.

I am trying to debug a project, suddenly I'm running into an issue where enumerating any object collections results in a timeout if I try to view it.If I run the program normally I have no issues. If I try to view any collection, such as a list, I get a timeout error and the whole thing bombs out.I thought something might be going on with one of my more complex collections so I tried creating just a normal list of strings as follows...
List<string> blah = new List<string>{"fsdf","fsdg","Gt","gsersg","ser","gersgxdrsd"};
