MVC :: Creating HTML Helpers With Extension Methods?

I have an extension method as follows:
public static class PageExtensions
{
public static int GetUserId(this Page targetPage)
{
var user = Membership.GetUser(targetPage.User.Identity.Name);
return (int)user.ProviderUserKey;
}
}
Now in a page I need to use this method in a static WebMethod, so I have added another 'extension method' to PageExtensions:
public static int GetUserId()
{
return (int)Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey;
}
and I call it as follows in my WebMethod: PageExtensions.GetUserId()
public class CacheHelper { /// <summary> /// Removes object with the specified key. /// </summary> /// <param name="key">The key.</param> [code]....
I have this methods for caching..I need to change this methods to use in aDictionary<string,object>
How do I need to change this code Because I am new to asp.net I am still learning..
I'm searching for some extension methods that helps programming in ASP.NET. Some functions to work on controls, validators, AJAX or programing in C# in general.It could be methods library or your own methods.Do you know any source of those methods (other than CodePlex - that is good source of generic extensions) especially for ASP.NET?

So, I am having a hard time getting this to work. I am trying to add some typographic HTML codes to some labels I have strongly typed to my model.
<%: Html.LabelFor(m => m.Name) %>
I am using data annotations to customize the DisplayName of the property:
[DisplayName("Your friend’s name")]
public string Name { get; set; }
However the actual code is being displayed for the label:
Your friend’s name
I have also tried just using the old write method:
<%= Html.LabelFor(m => m.Name) %>
Note , that i'm new to c# so it might not be a problem.first , what is the exact meaning of @ in Razor ?does it mean WebPage.Response.Write ?next, i designed an extension method to WebPage ( by the way that is the coolest feature ever in c# )in my Razor code , to use it in a webpage , i must write @this.MyExtensionMethod() instead of @MyExtensionMethod().So why is it? because @this.MyExtensionMethod() and @MyExtensionMethod() should be the same ?
here is my extension method :

With regards to the Razor view engine, say I want to render Html.TextBoxFor<SomeModel>(i => i.Name), it doesn't seem that the inline syntax works as in:
@Html.TextBoxFor<SomeModel>(i => i.Name)
This doesn't seem to work because it interprets the generic as an HTML tag. I could use a code-block approach, but then what's the best approach to output the content? The HTML string returned from this method, do I response.write it, or is there a syntax for it, or what's the approach?
I am trying to create an extension to extend the HtmlTextbox methods to allow our developers to add onkeydown inline javascript to auto click a button with a name they specify.

I have a web site project using the .NET 2.0 Framework that I am working on in Visual Studio 2008. I am using a third-party DLL in my project. I have added a reference to the DLL in my project and I can use everything as expected, including a number of extension methods for certain objects. Intellisense sees these extension methods, and I am able to make use of them and I can build my project on my local machine without any errors.
However, when running my website on a production server, I get a Compilation Error saying that the extension method I am trying to use could not be found. I can use everything else in the DLL besides the extension methods on the production server.
This is my first exposure to extension methods and understand what they are, but I can't seem to figure out why I can't make use of these methods outside of my local machine.

I'm using IOC containers that wrap items of HttpContext, such as Request and Session variables, to simplify mocking of it for testability.
Since IsAjaxRequest() is an extension method, it doesn't show up in HttpContext.Current.Request.
Is it possible to wrap extension methods with a IOC container? How?
In the previous version of our application we worked one we used MVC 1, so no area's. Following the ASP.NET MVC Best Practices by Kazi Manhur, I Created Extension methods of UrlHelper to generate your url from Route
Now with the new version, we are using MVC 2 and Areas. I was just wondering if one should implement it as before or have a new "best practice" regarding this emerged?
What I'm doing right now is:
1) Create a route in my area's route registration:
[Code]....
2) Creat an UrlHelper Extension method:
[Code]....
3) then just call it like this:
[Code]....
While typing this I started wondering what is the use of the ID you specify for the Area route..cant one just call the route using that?
Is it possible to do something like this inline in an ASPX page?
<%= Me.SomeExtensionMethod() %>
I can't seem to figure out how to get this to work properly. I'm receiving an error saying that "SomeExtensionMethod" is not a member of the current Page object. I've added the necessary <%@ Import Namespace="..." %> directive at the top of my page. This Does work in code-behind.This isn't vitally important, but it would be good to know how to do in the future.
We say that "GroupBy" and "OrderBy" methods from LINQ as Extension Methods.Then how about "variable.ToString()" and "string.Split()" menthods. Are these Extension methods.

View 1 RepliesI 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:
[code]....
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.
I´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,
