I'm using devExpress 11.1 with MVC 3/razor and i'm experiencing problems with putting html tags into the content of the tabs of the pageControl e.g. I would like to put <div id="someDiv"></div> into the content.
Did anyone encounter similar problems?
At present, you can follow recommendation from the "Using in Razor Views" topic and wait a little when the "Razor Demos" will be available.
ViewContext.Writer.Write() is used to write html tags inside contents. Just go through this example.
settings.SetContent(() =>
{
ViewContext.Writer.Write("<div class=accountHeader>");
ViewContext.Writer.Write("<h2>");
ViewContext.Writer.Write("Welcome to My Site");
ViewContext.Writer.Write("</h2>");
ViewContext.Writer.Write("</p>");
ViewContext.Writer.Write("</div>");
});

I have a MVC 3 project and I enable the HTML 5 markup. For the HTML 5 part, it is running fine.
Now I created a partial view and copy and paste some code into it
The first line is
<div id="Header">
I want to use this partial view in my view which is html 4 markup.
The problem comes, the razor engine automatically convert my
<div id="Header">
into
<Header>
I don't want to use HTML 5 for this view but only HTML 4. What should I do?
If you change the div as follows, it won't get swapped out:
<div id="strap">
Which may solve your immediate problem.
why do you want to covert back to:
<div id="Header">
where is the way to go in the future?
If you worried about the compatibility with the older browser, you can simply implement modernizr-2.6.2.js. (which should come with the Visual Studio web projects)
This will make all the basic HTML5 works in older browser.
(tho haven't tested with browser older than IE6)
you could always use a class instead of an id
<div class="header">
this has the added advantage of not making your css (if any) for this element very specific, and also means that the ID cannot be reused.
you can still select your element using jQuery selector using it's class as the selector
$('.header')
question for you: Did you created the Html 4 partial view in Html 5 view? ; If your answer is yes, the problem you mentioned is occurring naturally. When MVC renders your page, he first renders the Html 5 part(the layout master page). As a result, Html5 type doc type will be chosen by default. After that when the Html 4 partial view is rendered, the engine renders it under a mark up support for Html 5.
if i want to summarize what i wanted to say:
<html>
//Html 4 partial view.
</html>
This will make a Html 5 markup view no matter what Html4 code you wrote in that partial view. If i am wrong, let me know. I will learn from my mistakes. thanks.
Can you please use Transitional doctype on the top of your partial view page. Because HTML engine understand the page according to doctype.
I'm trying to wrap my head around something; maybe someone here can point me in the right direction.
Currently a have a form that has some controls on it like this:
#Html.ListBoxFor(s => s.SomeListSelection1, new MultiSelectList(Model.SomeList1, "Id", "Text"))
<br />
#Html.ListBoxFor(s => s.SomeListSelection2, new MultiSelectList(Model.SomeList2, "Id", "Text"))
<br />
#Html.ListBoxFor(s => s.SomeListSelection3, new MultiSelectList(Model.SomeList3, "Id", "Text"))
<br />
This form appears in many places with some slight variation on which controls are available.
The "slight variation" makes me not just want to do this as a partial view as I will either need to replicate the controls into many slightly varied partials or code the variation logic into the view.
So I think, "I know, I'll use the cool HTML Helper thingy!!"
But, all the HTML helper samples online are very simple html content. So the question is how can I use other HTML helpers inside an HTML helper? Or, if that is the wrong question is there another cleaner alternative to just making this a partial view with a bunch of conditional rendering logic?
Edit:
While the answer did technically answer my question, I had trouble making use of the blog entries for what I was trying to do. I found a better example (for me anyway) here:
ASP.NET MVC 3 Custom HTML Helpers- Best Practices/Uses
Yes, you can.
Helpers can contain arbitrary Razor markup.
In fact, the direct contents of a helper method is a code block, not markup.
For a more in-depth discussion about how helpers work, see my blog.
I want to create a reusable ajax control in MVC .NET using RAZOR.
my example is a simple ajax text box and list where the user filters the list by typing in the text box. on the first call i would render both the text box and the list using my razor view. on subsequent AJAX calls i would want to ONLY render the (now filtered) list.
idea 1: use #if statement to conditionally render code.
problem: razor does not seem to like conditionally written html. for example it errors when a <div> tag is not followed by a closing </div>.
idea 2: use #section tokens to create portions of my control and then call RenderSection within the same file as needed.
problem: razor does not allow RenderSection to call sections in the same page
i know i can conditionally render html as strings, but i wanted to take advantage of the legibility of the razor markup and keep with development protocols.
You should be able to output <div> tags in a Razor block without the corresponding </div> tag by surrounding it with <text>. The reason is that Razor uses the closing tag to know when to drag back into code-parsing mode:
#if (myCondition)
{
<text>
<div>
</text>
}
As for the Section stuff, you might be able to achieve what you want using Templated Razor Delegates, like this:
#{
Func<dynamic, object> b = #<strong>#item</strong>;
}
// ...
<span>This sentence is #b("In Bold").</span>
See Phil Haack's blog for a little more on this.
I have an MVC3 site using Razor as its view engine. I want my site to be skinnable. Most of the possible skins are similar enough that they can derive from a shared master layout.
Therefore, I am considering this design:
However, I would like to be able to call RenderSection in the bottom layer, _Common.cshtml, and have it render a section that is defined in the top layer, Detail.cshtml. This doesn't work: RenderSection apparently only renders sections that are defined the next layer up.
Of course, I can define each section in each skin. For instance, if _Common needs to call RenderSection("hd") for a section defined in Detail, I just place this in each _Skin and it works:
#section hd {
#RenderSection("hd")
}
This results in some duplication of code (since each skin must now have this same section) and generally feels messy. I'm still new to Razor, and it seems like I might be missing something obvious.
When debugging, I can see the complete list of defined sections in WebViewPage.SectionWritersStack. If I could just tell RenderSection to look through the entire list before giving up, it would find the section I need. Alas, SectionWritersStack is non-public.
Alternatively, if I could access the hierarchy of layout pages and attempt execution of RenderSection in each different context, I could locate the section I need. I'm probably missing something, but I don't see any way to do this.
Is there some way to accomplish this goal, other than the method I've already outlined?
This is in fact not possible today using the public API (other than using the section redefinition approach). You might have some luck using private reflection but that of course is a fragile approach. We will look into making this scenario easier in the next version of Razor.
In the meantime, here's a couple of blog posts I've written on the subject:
http://blogs.msdn.com/b/marcinon/archive/2010/12/08/optional-razor-sections-with-default-content.aspx
http://blogs.msdn.com/b/marcinon/archive/2010/12/15/razor-nested-layouts-and-redefined-sections.aspx
#helper ForwardSection( string section )
{
if (IsSectionDefined(section))
{
DefineSection(section, () => Write(RenderSection(section)));
}
}
Would this do the job ?
I'm not sure if this is possible in MVC 3 but in MVC 5 I am able to successfully do this using the following trick:
In ~/Views/Shared/_Common.cshtml write your common HTML code like:
<!DOCTYPE html>
<html lang="fa">
<head>
<title>Skinnable - #ViewBag.Title</title>
</head>
<body>
#RenderBody()
</body>
</html>
In ~/Views/_ViewStart.cshtml:
#{
Layout = "~/Views/Shared/_Common.cshtml";
}
Now all you have to do is to use the _Common.cshtml as the Layout for all the skins. For instance, in ~/Views/Shared/Skin1.cshtml:
#{
Layout = "~/Views/Shared/_Common.cshtml";
}
<p>Something specific to Skin1</p>
#RenderBody()
Now you can set the skin as your layout in controller or view based on your criteria. For example:
public ActionResult Index()
{
//....
if (user.SelectedSkin == Skins.Skin1)
return View("ViewName", "Skin1", model);
}
If you run the code above you should get a HTML page with both the content of Skin1.cshtml and _Common.cshtml
In short, you'll set the layout for the (skin) layout page.
Not sure if this will help you, but I wrote some extension methods to help "bubble up" sections from within partials, which should work for nested layouts as well.
Injecting content into specific sections from a partial view ASP.NET MVC 3 with Razor View Engine
Declare in child layout/view/partial
#using (Html.Delayed()) {
<b>show me multiple times, #Model.Whatever</b>
}
Render in any parent
#Html.RenderDelayed();
See the answer link for more use-cases, like only rendering one delayed block even if declared in a repeating view, rendering specific delayed blocks, etc.
I'm not quite sure how this works yet... trying to find documentation.
In my existing app I've got two different ways of rendering strings in my View
<%: model.something %>
<!-- or -->
<%= model.something %>
The first one is html encoded, and the second one is not.
Is there something similarly short in Razor? All I can find is this, which is the encoded version.
#model.something
I guess the best approach would be to use the Raw extension-method: #Html.Raw(Model.Something)
#Model.Something automatically HTML encodes. If you want to avoid HTML encoding (and you want this only if you are absolutely sure what you are doing) you could use #MvcHtmlString.Create(Model.Something) (basically everything that implements IHtmlString won't be encoded). Phil Haack blogged about the Razor view engine syntax.
