MVC :: Using A Partial In A Strongly Typed View?

Oct 4, 2010

I have an application that is going to allow a user to create records of type Customer and Seller that have one section in common, but other fields that are unique to their types.

Both of these types will have an address block for their create view.

If I have a strongly typed Customer or Seller view, how can I use the view partial (containing the address block) that I've created? I've tried creating a view model, but I don't know how to have the create page inherit the Customer model and the addressBlock partial inherit the addressBlockForm partial model...

C# - MVC Strongly Typed View With DropDownList

Jul 6, 2010

Long story short, I'm trying to add a few extra items to ViewData to make my life easier, and its an edge case that doesn't really justify its own model just for this one case. Keep reading for more specific details.

So I have a strongly typed edit view for one of my objects, everything works great until I try to put a dropdownlist on the view with an ID that does not match a property of my class.

I have this


My expectation is that in the controller action that accepts the POST, I will manually use the FormCollection[] to read out that ID and populate MyOtherModel with the correct ID.

How To Make A Custom Strongly Typed Html Helper Method

Dec 2, 2010

Now I found out how to create custom html helpers

using System;
namespace MvcApplication.Helpers {
public class InputlHelper {
public static string Input(this HtmlHelper helper, string name, string text) {
return String.Format("<input name='{0}'>{1}</input>", name, text);

Now how to turn it into a strongly typed helper method InputFor Like it is in the framework?I don't need the Html.TextBoxFor method, I know it exists. I am just curious in how to implement this behavior myself and used this as a simple example.PS. I was looking in the mvc source code but couldn't find a trace of this mysterious TextBoxFor. I only found TextBox. Am I looking at the wrong code?

Strongly Typed - How Much Time To Compile A View

Oct 1, 2010

How much time is spent compiling a view in ASP.NET?Of course I don't expect anyone to give me a number, but I think it's interesting to have an idea of how much time this takes because it could influence the way we implement things.For example, if the time is significant , then I might try to put every result that I need to display in the view in a model class instance (created just to hold the values in such a way that I don't even have to test for objects with null value) and then minimize to the maximum (uh?) the amount of C# code in the view thus decreasing the amount of time necessary to compile the view.Question Does this make sense? Give some thoughts on this one.

MVC :: Strongly Typed View With Constrained Generic?

Mar 17, 2010

Can my strongly typed view use a generic with a constraint? The type I want to pass to the view is

RoleGrantedToPerson<T> where T: Aggregate I don't know what T is at design time, only that it is a child of the base class 'Aggregate' I have tried using


but at runtime I get an error that the type of the view model supplied does not match the type required.

Is there some syntax/method to accomplish this?

MVC :: Strongly Typed HtmlHelpers And View Models?

Oct 26, 2010

I am not sure why this happens, but when I have an Html.TextBoxFor(model => model.SomeObject.SomeProperty), when I post, the property of that object is always null.

When I look at the markup generated, I see <input type="text" name="SomeObject_SomeProperty" id="SomeObject.SomeProperty" value = "" />

If I change the helper to Html.TextBoxFor(model => model.SomeObject.SomeProperty, new {id = "SomeProperty"}) the controller is then able to pick the value up. Why is this happening? I feel as though I shouldn't have to be specifiying the id for the textbox as it works when fine when not using child objects on a view model, IE <%: HtmlTextBoxFor(model => model.SomeProperty) %>.

I have controller method that looks something like this:


notice the commented out line. This method used to return an IEnumerable<Sport> but now that I have used a LINQ query it is returning an IEnumerable of an anonymous type (I think that's the correct terminology - please correct me if I'm wrong).

Question I have is...can I add a strongly-typed view based on this anonymous type and if not, how do I write a view that can access this collection?

C# - How To Post Form From View Strongly Typed To ViewModel?

Mar 31, 2011

I have a view model as such:

public class MyViewModel
public MyObject myObject{ get; set; }
public List<MyList> myList{ get; set; }

I have a view with a form strongly typed to MyViewModel This view allows you to enter values for the properties of MyObject, as well as create a list of MyList objects. The List part works fine although I thought that would be the more difficult of the two. Assuming MyObject has a property Description I create a textbox to enter the value as such:

@Html.EditorFor(x => x.myObject.Description);
The text box renders with an id of MyObject_Description...The problem is when I post this to my controller action, MyObject does not get bound at all(althought the list items do as they recieve the appropriate IDs of "MyViewModel_MyList[guid].myListValue")
What am I doing wrong here??
EDIT: more info
The first line of the view is:
@model MyApp.ViewModels.MyViewModel
And the Action method:
public ActionResult Create(MyViewModel myViewModel)
I am passing a new MyViewModel into the partial view to begin...
public ActionResult Create()
MyViewModel model = new MyViewModel();
return PartialView(model);
Ok When I render my partial view that contains the forms I call :
@{Html.RenderAction("Create", "MyController");}
this is called from within a View of type @model IEnumerable<MyApp.Models.MyObject>
(this view displays a list of currently existing MyOjects, and at the bottom the partial is rendered to allow the user to add another MyObject to the DB)

Viewmodel - Mvc Strongly Typed View Model With Multiselect

Jan 5, 2010

I would like to know how i can bind my form values to my strongly typed view from a MultiSelect box. Obviously when the form submits the multi-select box will submit a delittemered string of my values selected...what is the best way to convert this string of values back into a list of objects to attach to my model to be updated?

public class MyViewModel {
public List<Genre> GenreList {get; set;}
public List<string> Genres { get; set; }

When updating my model inside the controller i am using UpdateModel like below:
Account accountToUpdate = userSession.GetCurrentUser();

However i need to somehow get the values from the string back into objects. I beleive it may have something to do with model-binders but i can't find any good clear examples of how to do this.

MVC :: Razor: Strongly Typed View With Model Containing Collection Properties?

I want to have a strongly typed create view for this model, that allows you to insert 1 to many addresses and phone numbers as part of the view. Ideally, the Action is strongly typed as well:


What would this view look like to facilitate creating 1 to many Addresses and PhoneNumbers, as well as having the state re-created correctly if the ModelState fails when posting? I've tried a number of variations including EditorTemplates and can't figure out how to do this.

How To Make VisualStudio Intellisense Work In Html Properties Of Strongly Typed View

Feb 20, 2010

I think the title says it all, but to be clear:

If I put something like:

<%=Model.Project.Id %>

in the body of a strongly typed view, I get full intellisense for my model.

However, if I put:

<a href="/Projects/Edit/<%=Model.Project.Id %>">

With the script being written within an html property (in this case the href="" property), the intellisense doesn't work.I imagine this is a limitation of VisualStudio, but it seems this is a very common task and should be able to work. Is there a fix for this? Does my version of VisualStudio have a problem?
