As concluded in this thread http://forums.asp.net/t/1583508.aspx MVC 2 converts some disallowed characters in the 'id' property of tag to the HtmlHelper.IdAttributeDotReplacement but the code to do that is internal to mvc and not exposed as i can see. Will I need to copy the code into my project so my custom herlps can do the same?
View 4 RepliesIf I wanted to create a custom HTML helper and take advantage of the new in-built templating feature, how would I do that? It appears the templating features are internal?
View 3 RepliesSo the bottom line is that we are working on a large web based project in ASP.NET webforms that is extremely heavy on data editing operations and we are not getting the code reuse that we want out of the presentation layer. We are currently generating a good portion of our DAL and that works great. However, the strategies for standardizing, improving UI development time, and code reuse for the presentation layer are less clear. I have been researching DyanamicData, potential code generation, and writing our own custom controls, but i dont see an obvious place to focus our efforts.
View 1 RepliesI currently trying to convert a ASP.NET MVC2 application to ASP.NET MVC3 razor. I have a lot custom Html helper methods, which render html output, like the one below, which renders a button with some markup :
StringBuilder sb = new StringBuilder("<input type='submit' id='") .Append(buttonId) .Append("' name='" ) .Append(buttonId) .Append("' value='") .Append(buttonValue) .AppendLine("' class='myclass1 myclass2' />");return MvcHtmlString.Create(sb.ToString());
I'm about a custom WSDL File Generation for a Classic ASP.NET XML Web Service.
The issue is I didn't find out how to specify mandatory parameters in my WSDL, since ASP.NET Web Services are generated on ?WSDL location, I thought I would do that from Web Method Annotations, but I found no issue.
Also I have been on a pose where the developer could hide WSDL Generation by specifying a custom WSDL Binding. But in my case I need to let other system access ?WSDL location with a Customized WSDL.
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
<%=Html.TextBoxFor(model => Model.Category.OrderNo) %>
My html source looks like this
[code]....
How can i fix this?
Is it my understanding that Helper methods are really the place where you can do the hard core logic that we would have done in lets say custom controls in ASP.NET? For instance I work for a .com which uses classic ASP.NET. The nature of our site is VERY complex, so we reuse and render different forms for thousands of products. Every product could have a different configuration form. We have a very complext RenderForm.cs custom server control that performs all the logic. Based on some configuration settings from a table in the DB, it says ok, for Product 1123 it reads the setup (that our users confugure form our internal admin system) and takes that and spits out the dynamic form (using literal controls and what not) to the p age.
So I'm thinking MVC now. Yea yea, it's all done in the View. Well partially. You're still going to have a need to have some custom logic in some .cs where it's not all embeded in your view. That would be foolish to think you're not going to have some class that will spit out some HTML..like some very hard core extensive helper methods.
So my question is, are helper methods or class where you now do your custom server control type of logic? it's basically kind of the same concept in that you need a place to put your "hard core" HTML rendering logic in some class other than a controller. Your controller is not responsible for rendering. So helper methods I guess are the so-called custom server controls in a way that I have in classic ASP.NET, figuratively speaking. I just need a yes or now on is the consensus that helper methods is the place to do all my hard core reusable logic that spits out html to the page and where I can embed custom controls into my view? Looks like it.

I have been using web forms and I have been let down by them. I hate the way it mangles my element id's and names. I want to have full control over my html and have the ability to have multiple forms on one page.
I do not use view state or post backs. All my server communication is done using JQuery ajax and sometimes page methods.
My pages do not make use of any runat=server controls other than occasionally using the repeater.
For now I have been using inline code like the following but I like the mvc html helpers.
EXAMPLE:

At the moment, using the asp.net mvc framework is not an option but I would like to use the HTML helpers in my asp.net application.
Is this possible to use the mvc html helpers or do I have to create my ow helpers?
I just upgraded my mvc 1.0 project to 2.0 using the wizard. My project builds fine however, my html helpers that I have used, does not render the input's ID tag. For some reason, only some controls render and some do not. For example:

I thought it had to do with the fact that the value is empty, but from the two examples, they are nearly identical. Is this a bug? All was working before I upgraded.
Do they work with webmatrix and vb coding?this is from asp net webpages with razor in c#

With the release of mvc 3 rc, I've started playing around with the Razor engine. Has anybody gotten razor templated helpers to work? If so, how? I have a single helper in View/Helpers folder and a single layout page. If I move the code to the view page, it works. The error is ' not in context' for the method name. How and where do I correct this?
View 3 RepliesWhen using the template helpers in ASP.NET MVC, e.g. Html.EditorFor(x => x.Property) the rendered Html with have a capitalized ID - matching my property name. In order to standardize the ID's of all html elements I want this to be lower case. Rather than specifying the ID manually - which won't get updated if I rename my property, I'd like to establish a convention. I'm sure I read this was possible somewhere and I'm currently scanning the interwebz to find it.
View 2 RepliesI'm trying to follow a tutorials on how to use helpers to use video, audio, Twitter, etc. And for that I need Microsoft.Web.Helpers. But when I try to add it via NUPACK, the whole application crushes. Even when I remove the package, the application never recovers. Below is the error I'm getting.
[Code]....
Where can I get Microsoft.Web.Helpers so that I can just add it manually to my project.
is the NuGet downloadable package Microsoft-Web-Helpers an official Microsoft library?
View 8 RepliesI´m learning mvc and I found a problem. I have a product table that stores currencies in integers. On the other hand I have a table name currency that stores each int id with the currency name.
On html.dropdownlist I followed the pattern:
The name of the form field (ArtistId) The list of values for the dropdown, passed as a SelectList The Data Value field which should be posted back with the form The Data Text field which should be displayed in the dropdown list The Selected Value which is used to set the dropdown list value when the form is displayed
This was great for Forms in order to display selections. Right know I´m finishing my details views and I need to use the int id on product table but display the name on currency table associated to that int id.
Does anyone knows if it exist an html helper that renders the Data Text Field that should be dsiplayed on the View taking into consideration the int number?
Something like @html.display("Name", model.product.currencyid) where name is pulled from db.currency?.
So, most of the MVC examples I find are C#, so I seem to have trouble finding samples ....(bear with me, I'm a newbie) with that said, if anyone can point me in the right direction,
I simply want to be able to apply htmlattributes / styles to my select box

View 1 RepliesI am looking on Music store example:
In Model we have:
[Required(ErrorMessage = "An Album Title is required")]
public string Title { get; set; }
In a View we have a Razor code:
<div class="editor-field">
@Html.EditorFor(model => model.Title)
@Html.ValidationMessageFor(model => model.Title)
</div>
My questions: Where I can find definition of EditorFor and ValidationMessageFor helpers?
What is the meaning of "=>" in the above command?
Is there a way to force the MVC automatically generated code to follow the conventions you have set in your preferences? For example, I keep all curly braces on the same lines as their declaring class, method, etc, but when generating a controller, it completely disregards my settings. Is there a setting someplace to force the same code generation as other parts of project?

Can I seek some advice here if I want to incorporate some automated scaffolding in my MVC 2 web application what is the best way to go? Should I be considering: MVC 2 Templated Helpers, or Dynamic Data (with support for Entity Framework) Roughly speaking I want to layout my own website layout in MVC 2 but then:
for high usage use cases custom define the page, for CRUD maintenance pages hook the website menu to point to some scaffolded auto-generated pages (i.e. it is for this item that I ask the above question). I've had a look at the Dynamic Data pages where you can add/edit/delete all aspects of an EF entity, so it's this type of thing I'm after (e.g. have an Edit Person menu link that when click launches an auto maintenance page for Person)
i wrote mvc 2 application with target framework asp.net 4.0 but my hosting provider supports asp.net 3.5. then i set my project's target framework to 3.5 and i compiled successfully on localhost but when i run the application it says me:

In order to get Database.Open("sdfsdf"); to work in one of my MVC3 .cshtml pages I had to add a using statement at the top of the page.@using WebMatrix.Data.I added it to the Web.Config file under the <pages><namespaces> section and it didn't work.
1. Do .cshtml pages not respect that section in the web.config? If not
2. Do we need to add @using statements in every page? Or is there a better way?
I can't get helpers like @LinkShare.GetHtml and @Gravatar.GetHtml working despite have references to:
System.Web.WebPages
System.Web.Helpers
And adding @using statements.
3. What am I missing in order to get the helpers working in my MVC3 project?
