MVC :: Can't Use HtmlHelper In A Class That Extends ViewUserControl
Aug 24, 2010
I'm trying to override all the Html.TextBoxFor etc. methods. I want to make them non-static methods in a class that extends ViewUserControl. But, according to intellisense, Html does have access to these methods; they simply don't appear. So basically I want to do something like:
[Code]....
But I'm not getting the syntax right.
Basically just trying to wrap the TextBoxFor call so that my ViewUserControl can drop in a unique id each time.

I have an HTML Helper that essentially renders static content read from HTML files (inside of a vdir). There are cases when the HTML file has a title element defined and in such cases, the current page should use the given title. The content inside of the body should be rendered where the Helper class is referenced in the View.
This is how I call the helper.
<%=Html.StaticContent("staticcontent.htm",
new List<StaticContentTag>()
{
new StaticContentTag()
{TagKey=ReplaceTags.MarketName,
TagValue = "Austin"}
}, Model, true) %>
I'm passing in the ViewModel so that I can set the title and the last parameter is a flag that says whether to force the title or not.
The head has the title defined like this.
<title><%=Model.Title%></title>
I know what I'm doing wrong here by referencing the Model.Title element before even calling the helper. Any ideas on how I can work around this?

What are the advantages of extending HtmlHelper instead of creating a Custom Class.
f.e. <%= Html.Table(data) %> vs <%= CustomClass.Table(data) %>

I would like to extend the HtmlHelper by using metadata (similar to DataAnnotaions metadata). Specifically I want to be able to add a 'Title' attribute to html controls that will then appear as a tooltip on the control. I would like to keep the tooltip text with my model, for example by adding 'Tiltle' metadata to the model as follows:
[DisplayName("User Id")]
[Title("Enter your 10 digit user id")]
property UserId { get; set; }
So the questions are:
1. How do I add metadata (such as 'Title') to my model?
2. How do I access this metadata in my HtmlHelper extension method?

I have a gridview pulling all data from one user. This gridview has an edit button and when that is clicked the gridview becomes too wide for the div/screen and I get a scroll bar. Since this gridview can only have one user in it anyway is it possible to display each field on seperate lines instead?

I am new to MVC and I am trying to create my own extension method so that I can add onto the html helpers that are available in my razor views. Html.DropDownListFor() lets you create a drop down list for any propery on your model. I would like to create a helper called Html.StateDropDownListFor() that does the exact same thing, except loads the drop down with all 50 US states. This way I don't have to create a SelectList for every single state drop down that I create. What is the easiest way to do this? Right now I have this:
[code]....
Am I even close? I don't want to rebuild a whole text box helper, I just want to create a helper that utilizes the existing text box helper but does the SelectList for me. That way in my views I could just do Html.StateDropDownList(x => x.State)
[code]....

How can I call HtmlHelper methods outside of a view? I want to call Html.ActionLink from a C# method. Then use Response.Write to write the output from ActionLink to the output stream of a view. Is there a server side equivalent of HtmlHelper.ActionLink?

I am trying to debug a problem where HtmlHelper is null in extension methods. Oddly the debugger claims it's fully populated, however I consistently get null exceptions. I'm trying to figure out where HtmlHelper should being instantiated in an attempt to see where my problem may be.
Where should HtmlHelper be Instantiated?
Update: In particular I am trying to implement the extension found here, [URL] within a masterpage. The error occurs on the MVC template's HomeController.Index(). There are some 'plugins'/virtualpathing that may be causing the problem (trying to avoid this can of worms), but, code the code is essentially the same as found here: [URL]. However, I don't want to trouble anyone with the details of all of that.

I am developing a Web app that is based on ASP.NET 3.5, and i added some page from ASP.NET MVC, everything is ok, until i use the "HTML" helper class, then the page is not being able be render, because this is not recognized.
For Example : Html.BeginForm() => this is not recognize as a method
But if i used "System.Web.Mvc.Html.FormExtensions.BeginForm", which is a extension method itself, it work fine.
Environment : ASP.NET MVC 2 and ASP.NET 3.5

My View inherits Models.MyModel
<%@ Page Language="C#" MasterPageFile="Something.Master" Inherits="Models.MyModel>" %>
I need a property Model.Something to be available in a HtmlHelper method when I call it from this view.
<%= Html.CustomHelper(...) %>
Is there any way to access this? Maybe via ViewContext or ViewDataDictionary?
I do not want to explicitly pass Model.SessionKey for each helper I call.

I am using VS2010 & MVC2 to develop a web app. I noticed that HtmlHelper.LabelFor doesnt contain an override that accepts either a css class or html attributes. I was thinking about writing my own override for this, but am struggling with it.
The current LabelFor method accepts a lambda expression and automatically extrapolates the property name, display name (if specified via [DisplayName] attribute and value and generates the label. How do I write my overridden to do the same, but also insert any htmlAttributes specified such as class, style etc.
