MVC :: Strongly Typed Helpers Generate Wrong Input Nam When Are Used Inside Foreach?
Aug 5, 2010
I've got a problem with ASP.NET mvc stongly typed helpers.Here is example of wrong behavior:
[Code]....
will generate following inputs:
[Code]....
As you see generated name is wrong, because of wrong algorithm of extracting property name from lambda.The only way to avoid this bug is to create PartialView and pass item as its context.May be somebody knows other solutions? Do you consider it a bug or right behavior?
I am using the MetaDataType DataAnnotation to validate my models in an MVC2 application. I also apply the DisplayFormat annotation so that currencies and dates are formatted the way I want. This method works for the original Html Helpers such as :
[Code]....
When I used the new strongly typed helpers:
[Code]....
the formatting never gets applied. Is there a way around this?
I try to use HtmlHelper.TextBoxFor with spark view engine but view crashed with exception "Dynamic view compilation failed. 'System.Web.Mvc.HtmlHelper' does not contain a definition for 'TextBoxFor' and no extension method 'TextBoxFor' accepting a first argument of type 'System.Web.Mvc.HtmlHelper' could be found(are you missing a using directive or an assembly reference?)".
It is my _global.spark: <use namespace="System"/> <use namespace="System.Linq"/> <use namespace="System.Text" /> <use namespace="System.Web.Mvc"/> <use namespace="System.Web.Mvc.Html"/> <use namespace="System.Web.Routing"/> <use namespace="System.Linq.Expressions" /> <use namespace="MyModels" /> In spark-view using: ${Html.TextBoxFor(m => m.UserName)}
I am having a trouble while trying to create an entity with a custom view modeled create form. Below is my custom view model for Category Creation form.
[code]....
When i click on save button, it doesnt bind the category for me because of i am using custom view model and strongly typed html helpers like that
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?
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)
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...
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
[code]....
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 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.
is 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.
I'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?
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
