I try to follow the MVC tutorial: [URL] but in section "Listing 2 - ViewsHomeIndex.aspx"
I start getting problems. My news.aspx that should just das display the blogs in my database has the error:Name 'Model' is not declared strongly typed
[Code]....
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();
UpdateModel(accountToUpdate);
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.
Note: I'm working with MVC3 RC and Razor views.I've got this model:
[Code]....
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:
[Code]....
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.
I have a view that is strongly typed and its model is of type LogOnModel. That LogOnModel has anotated properties like this one:
[Required(ErrorMessage = "Please enter your password")]
[DataType(DataType.Password)]
[Display(Name = "Password", Description = "Your secreet password")]
public string Password { get; set; }
All of them has Display anotation with Display.Descripion property set. I want to create HtmlHelper extension method that will output <span> containg the value of Display.Description property. So for example if I called my extension method DescriptionFor than this code:
<%: Html.DescriptionFor(m => m.Password) %>
should produce following html: <span>Your secreet password</span>
So my question is more in relation to what people consider to be the best practice and why:
I've been dropping literals into pages and repeaters and binding them in code behind for a while. Is this considered bad practice?
ie:
ASPX Page:
<asp: Literal id="litTextToInsert" runat="Server" />
Code Behind:
litTextToInsert.Text = objData.MyText;
OR (repeater):
[code]....
I personally dont like doing this as i find it makes it harder for me to know if someone changed the field name, or mis typed it during development - the other way you won't know until the page loads.
With the strongly typed version if something changes in your DAL etc the build will break - letting me know I've messed up.
Why do so many people appear to use weakly typed code in ASP.Net (in examples, MVC, etc)?
Am i missing something?
Given the benefits of using strongly typed views to eliminate typed errors and the use of lambda expressions why would one use a dynamically typed view? When I use them I don't feel as safe as with strongly typed views. Am I missing something? Is there a special use for them?
View 2 RepliesMy error code:
string model = "Content";

How to do this ?
Been using MvcContrib for strongly typed redirects since MVC1. Aren't we there yet with MVC3 or did I miss something (just been scratching the surface)
View 5 RepliesI 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...

View 3 RepliesLong 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.

View 1 RepliesHow 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.
View 1 RepliesI have a Strongly typed Dataset TableAdapter in C#, how do I get a single row from it?
View 4 Repliesis it possible to do a batch update in a strongly typed data set? UpdateBatchSize does not seem to be an option once you create a strongly typed dataset.
View 1 RepliesI'm currently working on a 3-tier ASP.NET application (UI, BLL & DAL). The DAL uses a strongly typed dataset that I've created with the VS Dataset Wizard. My question is, what is the best way to handle exceptions originating from the BLL and DAL classes. I googled a bit and it seems that the most commonly used practice is to create DALException and BLLException classes and throw your own message. Is this the way forward? how this can be done for an automatically generated DAL? What are the best practices?
View 1 RepliesCan 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
System.Web.Mvc.ViewUserControl<RoleGrantedToPerson<Aggregate>>
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?

I am working with a third party asp.net application that uses master pages and nested master pages. My needs are to dynamically set the master page files for each page(.aspx). The application by default sets the master page file in the strongly typed @Page directive for each page. I don't want to change the strongly typed directive on each page (over 50 pages) because I am lazy and I want to minimize conflicts with future upgrades.
protected override void OnPreInit(EventArgs e)
{
this.MasterPageFile = "~/MasterPages/MyMaster.master";
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) %>.
In my Index() function, I have a query which is joining multiple tables. How do I transform this query into the object model which I am going to use in my view?
My view needs ProductInformation object.

The Index method is returning somethig like this:
public ActionResult Index()
{.....
var query = from .... join.... join ....join ....join select new {.....};
return View(query)
}
