You can use the `Html.Raw()` method for that.

And if you are using model in your view than use:


    @model YourApp.Models.YourModel
    ....
    
    @Html.Raw(@Model.NameOfYourProperty)

I am working on some CSS where the design calls for page titles (headings) to be centered with horizontal lines that are vertically centered on either side. Further, there is a background image on the page so the background of the title needs to be transparent. 

I have centered the title and I can use pseudo class to create the line. But I need the line disappear when it cross the text of the title. 

I considered using a background gradient that goes transparent where the words are, but since each title could be a different length, I wouldn&#39;t know where to put the stops. 

Here is the CSS so far:

    h1 {  
        text-align: center;  
        position: relative;  
        font-size: 30px;  
        z-index: 1;  
    }  

    h1:after {  
        content: &#39;&#39;;  
    	background-color: red;  
    	height: 1px;  
    	display: block;  
    	position: absolute;  
    	top: 18px;  
    	left: 0;  
        width: 100%;  
    }  

Here is where I&#39;m at:

Can this be done with CSS without adding any extra HTML?

On my main page, I have the code `@{Html.RenderPartial(&quot;_Partial1.cshtml&quot;);}`, and on my Partial, I have an HTML string:

    @{ 
        // The string is actually dynamic, not static. This is here for simplicity
        string abc=&quot;&lt;div class=\&quot;error\&quot;&gt;abc&lt;/div&gt;&quot;;
    } 
    @abc

I want to output `abc` with some CSS error styles, but I actually got `&lt;div class=&quot;error&quot;&gt;abc&lt;/div&gt;` - of course, no styles there. How do I make it interpreted as HTML source code and not a string?

how to access master page control from content page

I&#39;m implementing a website in Angular.js, which is hitting an ASP.NET WebAPI backend.

Angular.js has some in-built features to help with anti-csrf protection. On each http request, it will look for a cookie called &quot;XSRF-TOKEN&quot; and submit it as a header called &quot;X-XSRF-TOKEN&quot; .

This relies on the webserver being able to set the XSRF-TOKEN cookie after authenticating the user, and then checking the X-XSRF-TOKEN header for incoming requests.

The [Angular documentation][1] states:

&gt; To take advantage of this, your server needs to set a token in a JavaScript readable session cookie called XSRF-TOKEN on first HTTP GET request. On subsequent non-GET requests the server can verify that the cookie matches X-XSRF-TOKEN HTTP header, and therefore be sure that only JavaScript running on your domain could have read the token. The token must be unique for each user and must be verifiable by the server (to prevent the JavaScript making up its own tokens). We recommend that the token is a digest of your site&#39;s authentication cookie with salt for added security.

I couldn&#39;t find any good examples of this for ASP.NET WebAPI, so I&#39;ve rolled my own with help from various sources. My question is - can anyone see anything wrong with the code?

First I defined a simple helper class:

    public class CsrfTokenHelper
	{
		const string ConstantSalt = &quot;&lt;ARandomString&gt;&quot;;

		public string GenerateCsrfTokenFromAuthToken(string authToken)
		{
			return GenerateCookieFriendlyHash(authToken);
		}

		public bool DoesCsrfTokenMatchAuthToken(string csrfToken, string authToken) 
		{
			return csrfToken == GenerateCookieFriendlyHash(authToken);
		}

		private static string GenerateCookieFriendlyHash(string authToken)
		{
			using (var sha = SHA256.Create())
			{
				var computedHash = sha.ComputeHash(Encoding.Unicode.GetBytes(authToken + ConstantSalt));
				var cookieFriendlyHash = HttpServerUtility.UrlTokenEncode(computedHash);
				return cookieFriendlyHash;
			}
		}
	}

Then I have the following method in my authorisation controller, and I call it after I call   FormsAuthentication.SetAuthCookie():

		// http://www.asp.net/web-api/overview/security/preventing-cross-site-request-forgery-(csrf)-attacks
		// http://docs.angularjs.org/api/ng.$http
		private void SetCsrfCookie()
		{
			var authCookie = HttpContext.Current.Response.Cookies.Get(&quot;.ASPXAUTH&quot;);
			Debug.Assert(authCookie != null, &quot;authCookie != null&quot;);
			var csrfToken = new CsrfTokenHelper().GenerateCsrfTokenFromAuthToken(authCookie.Value);
			var csrfCookie = new HttpCookie(&quot;XSRF-TOKEN&quot;, csrfToken) {HttpOnly = false};
			HttpContext.Current.Response.Cookies.Add(csrfCookie);
		}

Then I have a custom attribute which I can add to controllers to make them check the csrf header:

    public class CheckCsrfHeaderAttribute : AuthorizeAttribute
	{
		//	http://stackoverflow.com/questions/11725988/problems-implementing-validatingantiforgerytoken-attribute-for-web-api-with-mvc
		protected override bool IsAuthorized(HttpActionContext context)
		{
			// get auth token from cookie
			var authCookie = HttpContext.Current.Request.Cookies[&quot;.ASPXAUTH&quot;];
			if (authCookie == null) return false;
			var authToken = authCookie.Value;

			// get csrf token from header
			var csrfToken = context.Request.Headers.GetValues(&quot;X-XSRF-TOKEN&quot;).FirstOrDefault();
			if (String.IsNullOrEmpty(csrfToken)) return false;

			// Verify that csrf token was generated from auth token
			// Since the csrf token should have gone out as a cookie, only our site should have been able to get it (via javascript) and return it in a header. 
			// This proves that our site made the request.
			return new CsrfTokenHelper().DoesCsrfTokenMatchAuthToken(csrfToken, authToken);
		}
	}

Lastly, I clear the Csrf token when the user logs out:

    HttpContext.Current.Response.Cookies.Remove(&quot;XSRF-TOKEN&quot;);

Can anyone spot any obvious (or not-so-obvious) problems with that approach?

I&#39;m looking for a way to programmatically get the summary portion of Xml-comments of a method in ASP.net.

I have looked at the previous related posts and they do not supply a way of doing so in a web environment. 

I can not use any 3rd party apps and due to a web environment, Visual studio plugin&#39;s aren&#39;t much use either.

The closest thing I have found to a working solution was the JimBlackler project, but it only works on DLL&#39;s.

Naturally, something like &#39;supply .CS file, get XML documentation&#39; would be optimal.

--- 
Current situation

I have a web-service and trying to dynamically generate documentation for it.

Reading the Methods, and properties is easy, but getting the Summary for each method is throwing me off a bit.

    /// &lt;summary&gt;
    /// This Is what I&#39;m trying to read
    /// &lt;/summary&gt;
    public class SomeClass()
    {
        /// &lt;summary&gt;
        /// This Is what I&#39;m trying to read
        /// &lt;/summary&gt;
        public void SomeMethod()
        {
        }

In a legacy ASP.NET project I have inherited, there are an abundance of methods defined  which are used absolutely nowhere.  

I&#39;m familiar with the &quot;Find usages&quot; functionality, but would like to be able to generate a list of methods which are not called anywhere in the app.  Does such functionality exist?

How can I use ReSharper to list unused methods in a solution?

The error I&#39;m getting is:

    Type &#39;OrgPermission&#39; in Assembly &#39;App_Code.ptjvczom, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null&#39; is not marked as serializable. 

here is my code:

I have a gridview, that uses the following DataSource:

   

     &lt;asp:ObjectDataSource ID=&quot;ObjectDataSource1&quot; runat=&quot;server&quot; SelectMethod=&quot;GetOrgList&quot; 
                TypeName=&quot;Org&quot;&gt;
        &lt;SelectParameters&gt;
          &lt;asp:SessionParameter Name=&quot;orgCodes&quot; SessionField=&quot;UserOrgs&quot; Type=&quot;Object&quot; /&gt;
           &lt;asp:Parameter DefaultValue=&quot;Y&quot; Name=&quot;active&quot; Type=&quot;String&quot; /&gt;
        &lt;/SelectParameters&gt;
     &lt;/asp:ObjectDataSource&gt;

I set the session variable in my page load like so:

    User cUser = new User(userid);
    //make sure the user is an Admin
    List&lt;OrgPermission&gt; orgs = new List&lt;OrgPermission&gt;();
    foreach(OrgPermission org in cUser.orgs)
       {
         if (org.type==&#39;admin&#39;)
         {
            orgs.Add(org);                       
         }
       }
    Session[&quot;UserOrgs&quot;] = orgs;

My user class looks like this:

    public class OrgPermission
    {
        public string Org { get; set; }   
        public List&lt;string&gt; type { get; set; }
    
        public OrgPermission()
        { }    
    }
    public class cUser
    {    
        public string userid { get; set; }
        public List&lt;OrgPermission&gt; orgs { get; set; }
    
    	public clsUser(string username)
    	{
          //i set everything here
        }
    }

I can&#39;t understand why it&#39;s breaking, can I use it without making it serializable?

I tried to debug, and the session variable sets just fine, it then goes into the GetOrgList and returned correct results, but the page does not load and I get the error above.

Here is a snippet of my GetOrgList function:


 

    public DataTable GetOrgList(List&lt;OrgPermission&gt; orgCodes, string active)
        {
    
            string orgList = null;
    
            //code to set OrgList using the parameter is here.
    
            DataSet ds = new DataSet();
            SqlConnection conn = new SqlConnection(cCon.getConn());
            SqlCommand cmd = new SqlCommand(&quot;sp_GetOrgList&quot;, conn);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.Add(new SqlParameter(&quot;@orgList&quot;, orgList));
            cmd.Parameters.Add(new SqlParameter(&quot;@active&quot;, active));
    
                conn.Open();
                SqlDataAdapter sqlDA = new SqlDataAdapter();
    
                sqlDA.SelectCommand = cmd;
                sqlDA.Fill(ds);
           
                conn.Close();
            return ds.Tables[0];
        }

Ok, I have tri-leveled entities with the following hierarchy: Course -&gt; Module -&gt; Chapter

Here was the original EF LINQ statement:

    Course course = db.Courses
                    .Include(i =&gt; i.Modules.Select(s =&gt; s.Chapters))
                    .Single(x =&gt; x.Id == id); 

Now, I want to include another entity called Lab which is associated with a course.

How do I include the Lab entity?

I tried the following but it didn&#39;t work:

    Course course = db.Courses
                    .Include(i =&gt; i.Modules.Select(s =&gt; s.Chapters) &amp;&amp; i.Lab)
                    .Single(x =&gt; x.Id == id); 

Any ideas on including the 2nd Entity?

Any piece of advise or information would be highly appreciated. Thanks!

Here is the problem. I am getting IEnumerable from ViewPage and when I tried it to convert List it is showing me error like:

&gt; &#39;`System.Collections.Generic.IEnumerable&lt;Pax_Detail&gt;`&#39; does not contain
&gt; a definition for &#39;ToList&#39; and no extension method &#39;ToList&#39; accepting a
&gt; first argument of type
&gt; &#39;`System.Collections.Generic.IEnumerable&lt;Pax_Detail&gt;`&#39; could be found
&gt; (are you missing a using directive or an assembly reference?)

Here is my controller code:

    [HttpPost]
    public ActionResult Edit_Booking(Booking model, IEnumerable&lt;Pax_Detail&gt; pax)
    {
      List&lt;Pax_Detail&gt; paxList = new List&lt;Pax_Detail&gt;();
      paxList = pax.ToList(); //getting error here
      BookingDL.Update_Booking(model, paxList);
      return View();
    }

I have applied same logic on another controller. And it is working fine. I don&#39;t know what problem it has. I have already clean, rebuild project and also restarted my laptop(though it was needed).

While Microsoft has created some [automagic rendering of html attributes][1] in razor MVC4, it took me quite some time to find out how to render a second css class on an element, based on a conditional razor expression. I would like to share it with you.

Based on a model property @Model.Details, I want to show or hide a list item. If there are details, a div should be shown, otherwise, it should be hidden. Using jQuery, all I need to do is add a class show or hide, respectively. For other purposes, I also want to add another class, &quot;details&quot;. So, my mark-up should be:

`&lt;div class=&quot;details show&quot;&gt;[Details]&lt;/div&gt;` or `&lt;div class=&quot;details hide&quot;&gt;[Details]&lt;/div&gt;`

Below, I show some failed attempts (resulting mark-up assuming there are no details).

This: `&lt;div @(@Model.Details.Count &gt; 0 ? &quot;class=details show&quot; : &quot;class=details hide&quot;)&gt;`,

will render this: `&lt;div class=&quot;details&quot; hide=&quot;&quot;&gt;`.

This: `&lt;div @(@Model.Details.Count &gt; 0 ? &quot;class=\&quot;details show\&quot;&quot; : &quot;class=\&quot;details hide\&quot;&quot;)&gt;`.

will render this: `&lt;div class=&quot;&quot;details&quot; hide&amp;quot;=&quot;&quot;&gt;`.

This: `&lt;div @(@Model.Details.Count &gt; 0 ? &quot;class=&#39;details show&#39;&quot; : &quot;class=&#39;details hide&#39;&quot;)&gt;`

will render this: `&lt;div class=&quot;&#39;details&quot; hide&amp;#39;=&quot;&quot;&gt;`.

None of these are correct mark-up.

How to add a second css class with a conditional value in razor MVC 4

I have the following model:

    public class Player
    {
 

        public String ImagePath
        {
            get
            {
                return &quot;~/Content/img/sql_error.JPG&quot;;
            }
 
        }

And, this is my `.cshtml` file:



    @model SoulMasters.Models.Game.Player
 
    @{
    ViewBag.Title = &quot;Game&quot;;
    Layout = &quot;~/Views/Shared/_GameLayout.cshtml&quot;;
    var imagePath = @Model.ImagePath;
    }
 
    &lt;fieldset&gt;
    &lt;legend&gt;Player&lt;/legend&gt;
 
       &lt;div class=&quot;display-field&quot;&gt;
        @Html.DisplayFor(model =&gt; model.ImagePath)
    &lt;/div&gt;
    @imagePath
    &lt;div style=&quot;padding:10px;&quot;&gt;
        
        &lt;img src=@imagePath alt=&quot;Sample Image&quot; width=&quot;300px&quot; /&gt;
        
        &lt;img  alt=&quot;asd&quot; &gt;
            model.ImagePath;
        &lt;/img&gt;
    &lt;/div&gt;
    &lt;/fieldset&gt;

The result is simple text:

    ~/Content/img/sql_error.JPG
    ~/Content/img/sql_error.JPG
    Sample Image asd model.ImagePath;

Also, I have tried the following line, and it works:

    &lt;img src=&quot;~/Content/img/sql_error.JPG&quot; alt=&quot;Sample Image&quot; width=&quot;300px&quot; /&gt;

 
How to display that image from path?
Could the image path be different based on settings? Any other ideas?

I&#39;ve recently installed VS 2012 Professional.

When i try to build my MVC4 Web Project. It doesn&#39;t recognize error in razor view when i do &quot;Build&quot; or &quot;Re-Build&quot;.

**Example** : &lt;br/&gt;
I removed a namespace from the project / or say renamed it. i build the solution, it gave me errors in all cs files, which i fixed by changing the namespace. The entire solution build successfully. When i run the project it gave me **Compilation Error** saying that namespace not found, because the old namespace was still referred in some of the views (*.cshtml files).

**Expected Solution** : &lt;br/&gt;
I wish when i do &quot;Build&quot; or &quot;Re-Build&quot;, it should recognize such errors and show me along with any other errors.

This was working fine with VS 2010, am i missing any configuration?

Thanks In Advance !!
