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?

I 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());
If 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 RepliesI'm trying to write a simple declarative html helper: [Code]....
The helper works fine if I embed it into the page I want to use it on. But if I move it to a separate .cshtml file and place that file in the ~/Views/Helpers directory, my view can't be compiled anymore because the helper is not found.According to Scott Gu's blog article on Razor it should work.
The only workaround I have found so far is placing the Html helper in App_Code and Referencing it as @[MYHTMLHELPERFILENAME].Echo(...) . This works but is a bit messy since I don't want to repeat the name of my extension method (Echo.Echo("inputstring"), nor do I want to put all of my html helpers into one single file (something like MyHtmlHelpers.cshtml).It certainly isn't what Scott announced either, so I guess I must be doing something wrong.
I don't know if this is possible but I would like to customize some of the HTML helpers autogenerated in the template. For example, I would like to replace the LabelFor with something that will allow me to specify an image with the label and also a ToolTip property so when you hover over the label you get the tool tip.
View 2 RepliesI would like to do some customizing to the T4 template used to generate code for views added using the Add View dialogue in VS 2010. Assuming this is, in fact, done with T4 like traditionally ASPX views, where can I find this template? I have successfully customised the ASPX template, but I can't recall where I found it.
View 2 RepliesI tried searching a bit and didn't find an answer. Does the Razor View Engine work in Mono?
View 3 RepliesWe have a modular architecture where we have some views (cshtml) files in a separate project (class library). How can we get the syntax highlighting and autocomplete to work when the project isn't an MVC project?
note that the class library has controllers, views, models etc. It just doesn't have the web.config, global.asax, etc that a normal mvc project would have.
The intellisense works for everything but the so important model:
With MVC3 RTM, if you hover over the Model, you can now get a better error message:

Then after adding the build provider, this error message appears:

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#

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 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

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)
