CKEditor and prefilling the textarea - asp.net-mvc

I am using MVC.NET and CKEditor and want to prefill the textarea so on edit forms the text is already loaded.
I try with:
<%= Html.TextBox("Message", Model.Message) %>
I can see that the textarea contains the correct text, but since CKEditor alters the html, it isn't inserted into the editor. Is there a way to hack it so I can insert the text into the form?

It was a stupid error, a simple:<%= Html.TextAreaFor(model => model.Message) %> made it work.

CKEditor is desined for WebForms and its designed in such a way to depend on the external dependencies like request and response.
Unless the CKEditor company provides the helper extension for MVC you will not be able to do that. You can also search if there is any extension points provided like interfaces.

What are the benefits, if i use rails view form template?

Example, i made a form like this
<form name="register" method="post" enctype="multipart/form-data">
<p><h3>User check</h3></p>
<p>admin ID: <input type="text" name="userid"></p>
<p>admin Pass: <input type="password" name="password"></p>
<input type="submit" name="apply" value="Submit"></p>
<p> </p>
</form>
and my manager wants to change this form to rails form template like this,
<%= form_for(:model) do |form| %>
<p>
<%=form.label :input%>
<%=form.text_field :input, :placeholder => 'Enter text here...'%>
</p>
<%end%>
My question is, it works fine with html based front code. Why do i have to change this to rails code? I just want to keep my front-end code...I don't know why i have to change this :(. Also, I'm new on Ruby on Rails. That is the main reason. I dont' want to change the existing code, if it is working.
I really hate this job. I have to translate all the attributes to the rails code and that makes me really exhausted :(
Form builders are here to help
Form helpers are supposed to make your life simpler. They are quicker to write than their pure html alternative, provided you don't write pure html first.
They also provide a lot of easy implementations for difficult integration pieces, like :
displaying a date selection select group
mirroring the fact that a check box has been unchecked in POST params
automatically adding multipart param on form if you add a file input (not actually difficult to achieve, but easy to forget)
... and many more
Further development
All of this is about comfort, and you may think you could avoid it if you already have a perfectly working pure html implementation.
But what happen if someone later has to add a date select input in your form ? She will have to use the rails helper, since it saves a lot of time in controller part to set date in database. But she won't be able to leverage form builder, since you haven't used it.
Now, she has to choose between using a non builderdate_select tag mixed in pure html or ... to rewrite your form completely. As you may realize, mixing different styles is generally considered ugly, and we don't like ugly in ruby.
Security
Form tag helpers also provide an important security measure : CSRF protection. Every time you use a rails helper to create a <form> tag, it automatically adds an hidden input containing a secret key. That key has to be posted with form data to prove request originated from current website.
If you use plain html forms, you won't have this security. You could of course add the token manually using the correct method, but this would again be more time wasting than simply using form helpers.
Bottom line
The main problem is that you write pure html before using rails helpers - that is what is wasting time.
Some benefits of using Rails form helpers are:
Consistent naming of input elements names and ids
i18n support for labels
generated URL with form_for is less error prone
Better handling of checkboxes
Nice helpers like options_for_select
Less typing
That last ones might be my favourite: less typing.

Redactor-Rails html tags showing

I'm trying to implement redactor as a WYSIWYG editor with ruby on rails. Everything seems to be working fine except that when I edit text in the editor the html tags show up. This happens even when I use the html button on the toolbar.
So on the webpage the text appears something like this:
<p>Edited text here</p>
I haven't included any code because I'm not really sure where to begin looking with this so any help at all will be appreciated :)
when using a text editor you have to tell your rails app that the area is html safe.
This is (by default) not the case as people could attack your site by using a text box you have put into your app.
by declaring an area as html safe you should be able to use the html tags as you like.
be aware of the security risk for using this.
e.g.
<div class="description">
<%= #foo.foo_desc.html_safe%>
</div>
Hope this clears it up for you.
in your view try using raw before the text you are trying to show. For example
<%= raw #post.body %>
this will work out with the html tags and show the processed text only without the tags.

Rails validation

I am suffering a issue with rails server side validation. Can some one help me out from this?
situation is :
I am creating dynamic for and its elements also dynamic.My application will generate the some HTMl code. Which can we use in any form or blog..
I applying the server side validation. But due to dynamic elements .I am not able to store the last entered value in to the elements. AS we normally does in PHP if user input something wrong we don't put the field empty. So I need to find a mechanism which fills the older values into the elements,If something went wrong.
This is the code into controller which is I'm using to show the form :
render :layout => false,:template=>'buildders/rander_form'
and view of rander_form.html.erb has
<%= render :file=>RAILS_ROOT+'/public/forms/form_'+#form_name+'.html.erb' %>
where #form_name is a dynamic form name(which have HTML code).
Can some one help me?
don't put erb files in public, people can download them by entering the file path in the url
also why not move that code out of the erb template into the controller?

how to show contents which include html tag?

I am using FckEditor in Create.aspx page in asp.net mvc application.
Since I need to show rich text in web pages, I used ValidateInput(false) attribute top of action method in controller class.
And I used Html.Encode(Model.Message) in Details.aspx to protect user's attack.
But, I had result what I did not want as following :
<p> Hello </p>
I wanted following result not above :
Hello
How can I show the text what user input?
Thanks in advance
The short answer is that HTMLEncode is making your markup show like that. If you don't HTMLEncode, it will do what you want.
You need to think about whether or not you need full control of markup, who is entering the markup, and if an alternative like BBCode is an option.
If your users using the editor are all sure to be 'safe' users, then XSS isn't likely to be as much a concern. However, if you are using this on a comment field, then BBCode, or something like SO itself uses is more appropriate.
You wont be able to use a WYSIWYG editor and do HTMLEncode though... (without BBCode, or some other token system)
It seems the user entered "<p> Hello </p>" (due to pressing Enter?) into the edit control, and it is displaying correct in the HTML as you have done an Html.Encode. E.g. the paragrahs are not rendered, they are outputted as "<p>..</p>" as the string is HTML encoded into something like "<p> Hello <p>".
If you do not want tags, I would suggest searching the text string for tags (things with <...>) and removing them from the inputted text. Do this before HTML.Encode.
...or am I missing something?
You can use HttpServerUtility.HtmlEncode(String)

Using HTML forms in ASP.NET MVC?

It seems like everything I look up on this subject has either changed since the release or is wildly different from eachother.
I just want to create a simple form in my view.
Should I be using the Html.BeginForm()/TextBox()/EndForm() methods or should I be using a plain-jane HTML form? Which is preferred?
This is what I have so far:
<%=Html.BeginForm("Create", "Product", FormMethod.Post); %>
<%=Html.TextBox("productTextBox", "Enter a shoe name"); %>
<input type="submit" name="createButton" value="Create Me!" />
<%=Html.EndForm(); %>
What is the "correct" way to create a simple form with a button and textbox in ASP.NET MVC and allow me to submit the data in the form to the /Product/Create action?
How do I then access the form data from within that method? Some people seem to use a "FormCollection" and others just do a Request.Form method. Which way should I use?
Can someone enlighten me?
The Form helpers are the recommended way because it allows you to provide a controller, action and other route data and the URL is auto-generated based on your routes (in Global.asax). The advantage is, if you decide to change your routes, you don't have to update every URL in your site.
The only reason I'd use an actual "<form>" tag was if I needed extra control over the markup that I couldn't get from Html.Form (I can't think of an example right now). Even if you choose to do that, you should use the "Url.Action" helper to get a URL from routing data. For example:
<form action="<%= Url.Action("Create") %>">
As for your second question, I'd suggest using the Model Binder. Check out ScottGu's Blog for some details on this.
Have a look at Link.
It's German text but the code should be understandable.
Have you looked at this:
http://weblogs.asp.net/scottgu/archive/2009/03/10/free-asp-net-mvc-ebook-tutorial.aspx
It's from the horse's mouth, and is up-to-date with the final release.
