I am returning data from my DB with multiple phrases. One of them being the following text : Submitted an Idea
I want to make the "Idea" in any an all text a hyperlink, so I want to use a replace function in my razor view to replace the word "Idea" with my Html Helper:
#item.RewardType.Replace("Idea", #Html.ActionLink("Idea", "ChallengeIdea", "Ideas", new { id = item.fkiIdeaId }, null))
I've looked around a bit but can not really find anything. Someone suggested using #Url.Action - But the issue remains the same.
How do I do this ? Or is using an Html helper the wrong way of doing this ?
Thanks for any help.
You can try this:
#Html.Raw(item.RewardType.Replace("Idea", $"<a href='/ideas/challengeidea/{item.fkiIdeaId}'>Idea</a>"))
Or
#Html.Raw(item.RewardType.Replace("Idea", "Idea"))
Html helpers are there to help you in general situations. When they produce more complications than value, they have no use
<span>Submitted an Idea</span>
If you have RewardType in a resource and can not use plain html, you could set RewardType to "Submitted an Idea" And use string.format

I have difficulty getting a value from a text area of the CKEditor
when I save something that has nothing inside the textarea HTML tag. In this case, it puts this text inside:
<html>\r\n\t<head>\r\n\t\t<title></title>\r\n\t</head>\r\n\t<body>\r\n\t</body>\r\n</html>\r\n"
Is there some way to strip off all these html tags?
I'm using MVC 3, and I've researched something about: Content(Server.HtmlEncode),
but I'm still not 100% if this is the best way to do this kind of treatment.
I found a class listed below that looks like it should solve your problem. Just add it to your solution and you can then call it statically and strip the html.
This kind of assumes that you are wanting to do the stripping of html on the server side.
On a side note not accepting answers like you are doing is hazardous to people willingness to help...I'd recommend that you reward the people that are helping you if you'd like to continue getting help!

#Html.DisplayTextFor(modelItem => item.content)
I need to embed links in my translated texts. I followed this post, but it doesn't seem to work in rails 3 anymore as the html tags don't get rendered properly.
Anyone knows how to get this done in rails 3?
Update:
Apparently, the html tags can be escaped by using the html_safe method. But does anyone know if there's another way to solve this problem without using html_safe?
I would like to avoid unescaping my html tags if possible, b/c I've encountered a situation where I have to pass in a text field into my translation, and I would like to avoid unescaping any strings that are user inputted.
Change {{url}} to %{url} and you should be good to go.
Update
Ok, thanks, that's important information about what "doesn't work" means :) So, you need to call the html_safe method on your call to link_to, eg.
link_to(t("log_in_href"), login_path).html_safe
This will tell Rails to render the HTML, not escaped.
Hi I'm working with a project (asp.net mvc) where I need to show pictures on one site. They gone have jquery and be surrounded by a div like <div><img/></div>
I'm relatively new on MVC so I'm not sure what ways are the best to work in it yet. Should I do a ImageHelper so i can access it like <% Html.ImageJquery() %> or should i just do it plain in the view
what are your thoughts on this?
I am not sure if there is any single best practice for this case. As you already said you could create an extension method on a HtmlHelper or just put the code in the view.
Because the "added" code is a very simple (just two divs) I would skip extension method and just add the divs in the view. But if the code is actually more complex I would create a helper.
Cheers!
It depends how often you would use the helper. If it is used in a couple of places it would make sense, because it helps you to reduce redundant code.
The other option you have are partials.
I would go with an Extension method on the HTMLHelper , so that it accepts the 'src' value as a parameter and constructs the image tag accordingly.
Regarding Rendering of UI elements , i did read a blog post on 'Conditional Rendering' which i thought you would find it interesting .

Conditional Rendering
Thanks ,

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)
Whenever I use Html.ActionLink it always Html encodes my display string. For instance I want my link to look like this:
More…
it outputs like this: More…
&hellip is "..." incase you were wondering.
However the actionlink outputs the actual text "…" as the link text. I have the same problem with if I want to output this:
<em>My-Post-Title-Here</em>
I wind up with:
<em>My-Post-Title-Here</em>
Any idea how to do this?
It looks like ActionLink always uses calls HttpUtility.Encode on the link text. You could use UrlHelper to generate the href and build the anchor tag yourself.
<a href='#Url.Action("Posts", ...)'>More…</a>
Alternatively you can "decode" the string you pass to ActionLink. Constructing the link in HTML seems to be slightly more readable (to me) - especially in Razor. Below is the equivalent for comparison.
#Html.ActionLink(HttpUtility.HtmlDecode("More…"), "Posts", ...)
The answer given by Sam is actually correct and I used it in my solution so I have therefore tried it myself.
You may want to remove the extra parenthesis so it becomes something like this:
#Html.ActionLink(HttpUtility.HtmlDecode("&"), "Index", "Home")
Alternatively, just use a plain Unicode ellipsis character \u2026 and let MVC worry about how to encode it. Unless there's some particularly compelling reason you'd specifically need a hellip entity reference as opposed to a character reference or just including the character as simple UTF-8 bytes.
Alternative alternatively: just use three periods. The ellipsis (U+2026) is a compatibility character, only included to round-trip to pre-Unicode encodings. It gets you very little compared to simple dots.
Check out this:
<p>Some text #(new HtmlString(stringToPaste)) </p>
Decode it before passing the value in. Just had this same issue (different characters) and it works fine:
Eg:
#Html.ActionLink(HttpUtility.HtmlDecode(_("&")), "Index", "Home")
Annoying though
