MVC :: How To Pass A Dictionary Type Of Data From View To Controller Using A HtmlHelper Control
Jun 17, 2010
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") %>,

My way to ASP.NET MVC was not across ASP.NET Web Forms, so it's hard for me to understand how better to pass value from ASP.NET MVC controller to ASP.NET webforms script which is inside MVC View.
For example, controller action:

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 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

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)

Is it possible to instantiate an HtmlHelper object in a controller action in order to call HtmlHelper.EditorFor?
I would like to call HtmlHelper.EditorFor to return some partial html generated by an editor template in response to an ajax call. If I can do so I would not need to create an ascx file that otherwise would do the call to EditorFor.

My View inherits Models.MyModel
<%@ Page Language="C#" MasterPageFile="Something.Master" Inherits="Models.MyModel>" %>
I need a property Model.Something to be available in a HtmlHelper method when I call it from this view.
<%= Html.CustomHelper(...) %>
Is there any way to access this? Maybe via ViewContext or ViewDataDictionary?
I do not want to explicitly pass Model.SessionKey for each helper I call.

In Asp.net Web forms why must a user control be partial? I tried to remove the partial keyword and it says: Missing partial modifier on declaration of type 'test'; another partial declaration of this type exists
Where is the other declaration?I am trying to pass a generic type with the user control how can I do that? I can't unless I change the other declaration too. I couldn't find it so I removed the partial keyword.Note:
you do have 3 files if your making WebApplication but if your making website you only get 2 files?
UserControl.ascx
UserControl.ascx.cs
so in website where is the other declaration?the reason i want generic is because im making a Grid User Control so i want to pass the type the datasource is going to have.
