I am displaying my 'news' page and I want the customer to be able to output some simple html.
My view looks like this:
#using SuburbanCustPortal.SuburbanService
<br />
#foreach (var item in (IEnumerable<TokenNews>) ViewBag.News)
{
<div class="fulldiv">
<fieldset>
<legend>#item.Title</legend>
<div>
#item.Body
</div>
</fieldset>
</div>
}
When I do it this away, the html isn't being rendered by the browser, it's just showing the html as text.
Any way that I can output the html where the browser will render it?
You didn't exactly specify what part is being shown as text, but if it's item.Body, do #Html.Raw(item.Body) instead. That turns a string into an IHtmlString, whose purpose is to tell Razor that this thing is guaranteed to be safe to output as-is, and will not contain nasties like XSS attacks (ensuring this when using Html.Raw is your job). Everything that is not an IHtmlString will be escaped automatically by Razor.

I have a Razor Pages layout page that includes a nav bar as a partial page
<html>
...
<body>
...
<partial name="_Nav" />
Inside my _Nav.cshtml
<div class="links">
link 1
link 2
<!-- custom links that are set by each page go here-->
</div>
This layout is used by every page in the website. I would like to be able include "extra" links that pertain to each page in the website.
I've tried doing it was #RenderSection, but it seems that sections are only allowed in the Layout page. Does this mean I need to do away with my _Nav partial and and lump all the code into one file? Or is there a way to keep an organized code structure and still pass some code around? With jinja2 code blocks this is no problem, so I'm hoping there is a nice way in Razor Pages as well!
Also, I really don't want to pass full html strings from the c# class out to the html, I'm already passing out any variables I need in the links.
Thanks for your help!
You don't have to store html in your ViewDataDictionary.
On every view that has extra links to add, store a List<string>, strings being urls, something like this:
View:
#{
ViewData["Links"] = new List<string>(){ "https://www.google.com", "https://www.facebook.com" };
}
Then in your Layout view:
<partial name="_Nav" view-data="#ViewData" />
Now in your partial view:
//Default Links
#if (ViewData["Links"] != null)
{
//We have extra links
List<string> links = (List<string>)ViewData["Links"];
foreach (string link in links)
{
link1
}
}
RenderSection can only be called from a layout page.
There is no such plugin to add the dynamic link to the partial view.
As a workaround,you could put a div outside the _Nav.cshtml like below and use RenderSection to dynamic add link to the div:
....
<div class="links">
<partial name="_Nav" />
#RenderSection("Html", required: false)
</div>
....
_Nav.cshtml:
link 1
link 2
Test View:
#page
#model IndexModel
//do your stuff...
#section Html
{
<a href='#link3'>link3</a>
}
how are you guys?
i have asp.net webform its for adding news in the news content i would like to use summernote http://summernote.org/ Super Simple WYSIWYG editor. as a WYSIWYG editor so could some one please help me to save the data from this editor
this is my code
<div class="form-body">
<div class="form-group last">
<label class="control-label col-md-2">News Content</label>
<div class="col-md-10">
<div name="summernote" id="summernote_1"> </div>
<asp:label runat="server" text="Label" ID="news_con" ></asp:label>
</div>
</div>
</div>
i can't get the text value from the summernote
by this code
news_con.Text = Request.Form["summernote_1"];
Have you considered using a <textarea> to handle this as opposed to a <div>? Usually they are a bit easier to use with respect to storing values (as they are designed to do so) :
<textarea id="txtTest" runat="server"></textarea>
One of the ways that you might handle this would be to register an event using Summernote's available API to set the HTML content for your <textarea> element whenever focus was lost (e.g. the onblur) :
<script>
$(function () {
// Set up your summernote instance
$("#txtTest").summernote();
// When the summernote instance loses focus, update the content of your <textarea>
$("#txtTest").on('summernote.blur', function () {
$('#txtTest').html($('#txtTest').summernote('code'));
});
});
</script>
Since you are likely going to be storing HTML content within the element, you'll likely want to ensure that .NET doesn't think you are trying to exploit it. You can do this by either explicitly setting this page to ignore that process by updating the ValidateRequest property of your page :
<%# Page ... ValidateRequest = "false" %>
Or you could try simply escaping the content that is being set :
$('#txtTest').html(escape($('#txtTest').summernote('code')));
I am trying to implement what I think is a pretty standard "dashboard" layout. The trick is I know ASP.NET but not so familiar with MVC so this is a learning project.
I have read many an article and they have helped me progress right to the point where I am very stuck and confused.
Part of my confusion comes from an existing advanced MVC project that I am familiar with from a user perspective. This helps in that I am able to pick through the source code and match up what I am learning to what I have seen from the user perspective.
This is not the problem just an example...
For example I read here what I believe is a very good introduction to the concepts. (http://www.codeproject.com/Articles/383145/RenderBody-RenderPage-and-RenderSection-methods-in)
In the MVC project I get to pick through however I see in the _Layout
#if (IsSectionDefined("statusbar"))
{
#RenderSection("statusbar")
}
however #section statusbar is not defined in the _Layout. If I do a global search for #section I find this:
#{
Layout = "~/Views/Shared/_Layout.cshtml";
}
#section header
{
}
#section headermenu
{
}
#section statusbar
{
}
#RenderBody()
So am I correct in guessing that statusbar is defined but it is an empty shell?
If it is an empty shell how does it get populated...cause when the project is running the statusbar does indeed have information???
So again this isn't my problem it is just an example of how the information at hand is confusing me.
This IS the problem:I'm not sure when to use PartialView, RenderSection...etc
My layout renders goofy. What is goofy? The only thing I can think of is to show you a screenshot of what happens.
What I want...
Here is the code used to generate these pages. The tags etc. for bootstrap etc. are omitted for brevity.
_Layout.cshtml
<!DOCTYPE html>
<html lang="en">
<head>
<title>#PageTitle</title>
</head>
<body>
<div class="container-fluid">
<div class="row">
<div class="col-md-12">
Header Stuff
</div>
</div>
<div class="row">
<div class="col-md-4">
#RenderBody()
</div>
<div class="col-md-8">
Main Content
</div>
</div>
<div class="row">
<div class="col-md-12">
Footer Stuff
</div>
</div>
</div>
</body>
</html>
Index.cshtml
#model DashboardModel
#{
Layout = "~/Views/Shared/_Layout.cshtml";
}
<div class="col-md-1">
<nav id="Navbar" class="navbar navbar-left" role="navigation">
<div id="organizer">
#(Html.Kendo().PanelBar()....etc....)
</div>
</nav>
</div>
<div class="col-md-3">
This is a place holder for my subnav...????
</div>
Stuff1Link cshtml
#model StuffModel
<div style="height:400px; border:dashed; border-width:thick;">
#{ Html.Kendo().MobileLayout().Name("mlay_PropStatus"); }
#(Html.Kendo().MobileView().....
</div>
Seems like layout is not put in Stuff1Link.cshtml
Can you put it like,
#{
Layout = "~/Views/Shared/_Layout.cshtml";
}
1.If your view just has some Html code just use "PartialView" :
#Html.Partial("_theLastPost")
2.If your view has controller for passing data it's better use "RenderAction":
#{ Html.RenderAction("_theLastPost"); }
and its controller
public PartialViewResult _theLastPost()
{
var a = (from c in db.Posts
orderby c.ID_Post descending
select c);
return PartialView(a);
}
3.I do not use render section . For more information about RenderSection go asp.net mvc layouts and sections with razor
I've got a post on my blog that discusses some of this you might want to check out.
The layout code you're referencing doesn't make much sense. The only purpose to declaring an empty section, really, is to fulfill a requirement that it exists, when you don't want to actually pass anything there. Since the layout is what defines whether it must be present or not, it makes no sense for it to exist there, empty. More than that, if you implement a section in your base layout, you'll get a runtime error because there's no place higher in the view chain where it's defined.
Long and short, to provide a place holder in your layout for a section you use:
#RenderSection("SectionName", [true|false])
The boolean param indicates whether views that utilize this layout must implement the section; false means it's optional, while true means it's required.
To implement a section in a view, you use:
#section SectionName
{
...
}
If you have a layout that inherits from another layout, that layout must implement all required sections in the layout it inherits from. If you want the the section to be available to views that utilize the sub-layout, you must redefine the section in the section implementation:
_Layout.cshtml
#RenderSection("Foo", true)
_SubLayout.cshtml
#{ Layout = "Views\Shared\_Layout.cshtml"; }
#section Foo
{
#RenderSection("Foo", true)
}
Finally, as to partial views vs. sections, it all comes down to whether you want to insert something into the layout or the view. For example, sections are most commonly used for inserting link tags to CSS files in the head or script tags before the closing body tag, where the view itself would not be able to touch directly. However, it's almost an apples and oranges comparison. Partials can be utilized in the layout, in the view, or even in a section. Whereas, sections can only be utilized in the layout.
I have following type of data stored in my database field
<p>sdf'jsdfkl''jksdl;fj/ sdfjklf'' Hiee</p>
<p> </p>
<p><strong>dfgdgdgfgsd</strong></p>
<p><strong>fsfsfsf</strong></p>
<p><strong>dfsfsdff</strong></p>
<p> </p>
<p><strong><img src="../Scripts/tinymce/plugins/emoticons/img/smiley-cool.gif" alt="" /></strong></p>
<p> </p>
<p>Hie this text comes out from TextEditor.. 'sf'fsfdfs'df'f''""'"sdfsfskfkf/lfdjklsfj\jslfjklff</p>
I have stored it in SQL server in ASP.net C# using HttpUtility.HtmlEncode() method.
Now i want to retrieve that data from database and want to display it without html tags..
For that I have used HttpUtility.HtmlDecode(), but that only decodes and generate tags and generated following result
<p>sdf'jsdfkl''jksdl;fj/ sdfjklf'' Hiee</p> <p> </p> <p><strong>dfgdgdgfgsd</strong></p> <p><strong>fsfsfsf</strong></p> <p><strong>dfsfsdff</strong></p> <p> </p> <p><strong><img src="../Scripts/tinymce/plugins/emoticons/img/smiley-cool.gif" alt="" /></strong></p> <p> </p> <p>Hie this text comes out from TextEditor.. 'sf'fsfdfs'df'f''""'"sdfsfskfkf/lfdjklsfj\jslfjklff</p>
I don't want to display all these tags, instead just want to display text, so what should i do??
You can use Html.Raw() on view or partial view for display html.
Html.Raw("<div class=\"resource-row\">").ToString()
I have bunch of HTML code I am using to make rounded edge boxes on my controls. Is there a way to take this code and turn it into some kind of control or something so I do not have to keep pasting 10 lines of HTML code around everything I do?
<div id="BottomBody">
<div class="box1024" >
<div class="content1024">
<div class="top1024"></div>
<h1>My Header Information</h1>
<hr />
<p>Some text for everyone!</p>
</div>
<div class="bottom1024">
<div></div>
</div>
</div>
</div>
One additional thing to note, the number HTML tags used inside the inner most DIV will change depending on where I use it in my site. So in some cases I will only have 1 tag and 1 tag but in other cases I could have 1 tag, 1 tag, 3 tags, and a HTML table. How can I make that work?
Yes, you're thinking of a UserControl. Extract the relevant HTML out, paste it into a UserControl .ascx template.
Now in your case, you'll probably want the text to be customizable, am I right? So you'll need to replace the <h1> through </p> bit with an ASP.NET label. The resulting .ascx HTML (not counting the #Control directive) will look something like:
<div id="BottomBody">
<div class="box1024" >
<div class="content1024">
<div class="top1024"></div>
<asp:Label runat="Server" id="label1" />
</div>
<div class="bottom1024">
<div></div>
</div>
</div>
</div>
Alternatively, you could do two labels -- one for the header, one for the main text. Or even just have the header be runat="Server" itself.
Next, you'll write a little bit of code in the .ascx code-behind file to expose the label's (or labels', as the case may be) Text property. This would probably look something like:
public string Text
{
get { return label1.Text; }
set { label1.Text = value; }
}
If you're in an ASP.NET MVC world, use your Model data instead of a label, and pass in the desired display text string as the model data.
Edit
Addressing the update to the question:
One additional thing to note, the
number HTML tags used inside the inner
most DIV will change depending on
where I use it in my site. So in some
cases I will only have 1 tag and 1
tag but in other cases I could have 1
tag, 1
tag, 3 tags, and a HTML table. How can
I make that work?
The exact same technique, assuming that the content you're referring to is what's within <div class="content1024">. The Text property of a label can contain any desired arbitrary HTML, and of course you can pass any arbitrary amount of HTML as a string to the Model if you're using MVC.
Another left field approach - create a user control but use jQuery to round the corners for you:
<div class="roundcorner">
<h1>My Header Information</h1>
<hr />
<asp:Label runat="Server" id="label1" />
</div>
Issue the following in javascript:
$(document).ready(function(){
$('div.roundedcorner').corner();
});
This eliminates all your extra div's and you can still have a user control that you use at will on the server.
(I know I'm going to get in trouble for this from someone)
If its just static content you can just put it in a separate file and INCLUDE it
<!--#INCLUDE VIRTUAL="/_includes/i_yourfile.htm" -->
(File name, extension and location are arbitrary)
