MVC :: 3 HtmlHelper.BeginForm - Return View?
Feb 11, 2011
I am having some trouble with returning a View in response to an ActionResult method being invoked. In my view I have a ViewData which holds a value which is being read. Current process.. user selects 1 of three radio buttons, and clicks a button to apply the selection, which in turn triggers method which sets the form ..
this.form =
this.htmlHelper.BeginForm("GridEditingMode",
"Classification")
Now in my controller, I change the value in the ViewData and simply which to return to the View();. Here is we're the fun starts.. I receive the following message, and cannot get around it. The view 'GridEditingMode' or its master was not found. The following locations were searched:

I have the following code:
public static PartialViewResult DateTime(this HtmlHelper helper)
{
return System.DateTime.Now.ToLongTimeString();
}
and now I want to return a Partial view from inside the DateTime method. But helper instance does not have any method for partial view.

When I put a part of my form in a partial view, all form parts get unobstructive syntax except the form elements in the partial view. The only way I found how to "apply" the unobstructive syntax, is by starting another form inside the partial view.
@using (Ajax.BeginForm("SubmitHandler", new DefaultAjaxOptions()))
{
@Html.EditorFor(m => m.Name)
@Html.Partial("MyPartialView", Model)
}
PartialView:
@Html.TextBoxFor(m => m.SomeContent)
<input class="text-box single-line" data-val="true" data-val-required="This field is required." id="Name" name="Name" type="text" value="">
<input id="SomeContent" name="SomeContent" type="text" value="0">
So only the input element from the View has the unobstructive syntax and the partial view hasn't... Is there a way to apply unobstructive syntax inside a partial view, wich doesn't require you to begin a new form?

How can I call HtmlHelper methods outside of a view? I want to call Html.ActionLink from a C# method. Then use Response.Write to write the output from ActionLink to the output stream of a view. Is there a server side equivalent of HtmlHelper.ActionLink?

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.

I would like to know what the pros and cons are of creating an extension method v a partial view. From my understanding, htmlHelper extension methods are better as they enable one to unit test the view.
e.g. Assert.AreEqual(Html.Price(), "<td><tr><td>Price</td><td>4.50</td></tr>");
where the Price() method contains the presentation logic.
Since both the extension method and partial view are reusable, what then is the point / benefit of a partial view?

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 would like to extend the HtmlHelper by using metadata (similar to DataAnnotaions metadata). Specifically I want to be able to add a 'Title' attribute to html controls that will then appear as a tooltip on the control. I would like to keep the tooltip text with my model, for example by adding 'Tiltle' metadata to the model as follows:
[DisplayName("User Id")]
[Title("Enter your 10 digit user id")]
property UserId { get; set; }
So the questions are:
1. How do I add metadata (such as 'Title') to my model?
2. How do I access this metadata in my HtmlHelper extension method?

How can I use use an actionResult to return both a view and a partial view. Actually in case of an ajax request it should send a partial view else it should send a view.
public ActionResult Test(string Name ="", DateTime? Date= null, string sex="" )
{
myModel model = new myModel(Name, Date, Sex);
if(IsAjaxRequest)
return PartialView("partialView", model)
else
return View(model);
}

I came upon this when had problem trying to return a view of a different controller.
In controller1, I have view view1.
In Action1 of controller2, I wanted to do something like:
public ViewResult Action1()
{
return View("/Controller1/View1");
}
but, found out, I couldn't do it. So I searched and found this:[URL]
One guy there responded and said that, for my case, it is possible to do things like below:
return View("~/Views/Controller1/View1.aspx");
this is considered an acceptable MVC practice. Is it OK, good, perfect to do so in the asp.net MVC realm?

Is there a way to return the same view every time a HttpNotFoundResult is returned from a controller? How do you specify this view? I'm guessing configuring a 404 page in the web.config might work, but I wanted to know if there was a better way to handle this result.
Edit / Follow up:
I ended up using the solution found in the second answer to this question with some slight tweaks for ASP.Net MVC 3 to handle my 404s: How can I properly handle 404s in ASP.Net MVC?

I have say class/ojbect one which I am returning as details. But then there is a second class that is related to the first that I want to list (and have an option to look at the details). How do I get return both of those?
Example is like in an item as the main piece but there may be details or other items that are related to the main item. I will select them with a linq query but then how do I return them to the same view?
Do I need to have some sort of partial or other form to display the second object type? I don't see where returning the view I can return both.
My thought for right now is to create a new class that contains both of the object types but I know there has to be a better way.

I have a list of items(surveys) displayed on my home page. When I click the edit button for a particular item I have a modal pop up with the items details to edit. When the user clicks Save I submit the form via ajax. Depending on whether ModelState.IsValid == true I want to update the modal with validation information or close the modal and update the list of items with the new information.
This is how I am submitting the form:
[Code]...
My Questions
The only thing I can think to do is return JSON from my controller with a flag indicating the state of the ModelState.IsValid and the corresponding partial that I should show.
1) How would I do this?
2) Is there a better way?
Update
I found this: [URL]
but it seems more likely that I am going about the whole thing incorrectly.

I have two tables: Projects and ProjectsData and I want to execute query with join and get the result in the View. In the Controller I have this code:
ViewBag.projectsData = (from pd in db.ProjectsData
join p in db.Projects on pd.ProjectId equals p.ID
where pd.UserName == this.HttpContext.User.Identity.Name
orderby p.Name, p.ProjectNo
select new { ProjectData = pd, Project = p });
What I should use in the View to extract this data. I tried that:
@foreach (var item in ViewBag.projectsData)
{
@item.pd.UserName
}
but it doesn't work.

I am just wondering whether it is possible to return the name of the view an ascx control is currently being rendered in? Is there an object I can use to access the name?
Basically I want the control to dynamically set certain text within itself dependant on the view it is rendered within.

I want to get data from Projects(which have CourseId) and related CourseName from Courses table.
I have written following code:
var projects = from n in db.Projects
join c in db.Courses on n.CourseId equals c.ID
orderby n.Name
select new { Project = n, Course = c };
return View(projects.ToList());
and I get error:
The model item passed into the dictionary is of type 'System.Collections.Generic.List1[<>f__AnonymousType22[ProjectManager.Models.Project,ProjectManager.Models.Course]]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[ProjectManager.Models.Project]'.
What I need to do in Controller and in View to display this data?

I want to be able to do a join query between my two tables Accounts and BankTransactions. This is a one to many relationship, there can be multiple BankTransactions per Account. I want to query this and display the account information including all the bank statements that are associated with it. I did a join in order to get it, but I am having trouble handling the model.
