I've created an Area in my app called "Admin" and when I attempt to use #html.actionlink() to build some menu items I'm met with a reference error.
system.web.WebPages.Html.HtmlHelper does not contain a definition for ActionLink and the best extension method overload System.Web.Html.LinkExtensions.ActionLink(System.Web.HtmlHelper,string, string, string) has some invalid arguments.
This is the line of code that's generating the error.
#Html.ActionLink("Posts", "Index", new { area = "admin" });
I've googled around and attempted adding using system.web.mvc.html; with no benefit or change in behavior. I've checked the web.config file for the area and confirmed that both system.web.mvc and system.web.mvc.html are included in the namespaces, also to no avail.
You are using actionlink wrongly.
Below is the correct usage of actionlink(i m taking example of any arbitrary actionlink)
Html.ActionLink(article.Title, // <--Link Text
"Item", // <-- ActionMethod
"Login", // <-- Controller Name.
new { id = article.ArticleID }, // <-- Route arguments.
null // <-- htmlArguments
)
This uses the following method ActionLink signature:
public static string ActionLink(this HtmlHelper htmlHelper,
string linkText,
string actionName,
string controllerName,
object values,
object htmlAttributes)
The error is coming in your question because 3rd overload of Actionlink is controller name.
#Html.ActionLink("// Link Text //", "// Action Name //",// controller name //, new { area = "admin" });
You are missing a web.config in your /Areas/Admin/Views folder. Just create the basic one like below, the key part being the added namespaces:

I have been working on a C# console application which uses a number of 3rd party dlls which are referenced in the project.
Everything was working fine but one day my windows 7 operating system updated because of automatic windows update and after that this application code started crashing at the code where a call is made to a 3rd party dll which actually accessing the database.
I restored my system to a previous state and the application started working fine again but once again the windows update ran and application started crashing again at the same location.
I can not stop windows update as its a company provided laptop and I can not change setting so that windows update do not happen again. And I do not have the code for this 3rd party dll.
I can provide you the app.config here...

The code where my application is crashing or giving exception is below:
public DataSet GetData(string statementId, string parameter)
{
object[] param = null;
DataSet ds = null;
try
{
if (parameter != null)
{
param = new object[1];
param[0] = parameter;
ds = DataAccessFaçadeAdapter.ExecuteStatementForDataSet(statementId, param);
}
else
{
ds = ExecuteStoredProcedure(statementId);
}
}
catch (Exception ex)
{
Tracer.Trace(TraceLevel.Error, "GetData() Exception is" + ex.Message);
}
return ds;
}
here the following line is where I get exception as this method is written in 3rd party dll for which I do not have any code
ds = DataAccessFaçadeAdapter.ExecuteStatementForDataSet(statementId, param);
And the Exceptions details are as below:
- InnerException {"Object reference not set to an instance of an object."} System.Exception {System.NullReferenceException}
Message "Object reference not set to an instance of an object." string

Please advise on how to resolve.
Determine if the third party DLL has an update. Usually system updates target discovered security holes and this targeted dll may have some issue related.
Otherwise you may want to implement a different method of data access or even move the application to .Net 4 which may have the latest methodology.
Why my app opens empty page and doesn't go to any redirect link after route page ??
I work on C# , MVC , Visual studio 2010
this is my login action:
[HttpGet]
[AllowAnonymous]
public ActionResult Login()
{
return View();
}
[HttpPost]
[AllowAnonymous]
public ActionResult Login(string name, string psw)
{
if ((Membership.ValidateUser(name, psw)) == true)
{
FormsAuthentication.SetAuthCookie(name, false);
if ((Roles.IsUserInRole(name, "Admin")) == true)
{
return this.RedirectToAction("AboutDetails_Admin", "mytask");
}
else if ((Roles.IsUserInRole(name, "People")) == true)
{
return this.RedirectToAction("TMembersDetails_Admin", "mytask");
}
else return View();
}
else return this.RedirectToAction("Register", "Default");
}
and this is the login view:
#{
ViewBag.Title = "Login";
Layout = "~/Views/_LayoutPage1.cshtml";
}
<h2>Login</h2>
<form action="/Default/Login" method="post">
<label>Full Name:</label><input type="text" name="name" /><br />
<label>Password:</label><input type="text" name="psw" /><br />

}
}
what can I do to make my index page redirect to the login page and not open empty page with http://localhost:1889/Default/Login
I found the mistake ,
in the first in visual studio 2015 when I choosed new project It make the the project Authentication : individual by default , so it resultd empty pages when project run ..
when I change authentication (in the first) to No authentication so it works now.
I have console project with some .cshtml files stored in Resources folder, which is built into .cs files with Razorgenerator.MsBuild nuget package.
I need to replace WebViewPage view base class for generated view, but adding web.config file with pageBaseType="ConsoleApp.MyViewBase" option set or changing location of files in different ways did not help me and no any other ways where found.
View class is always generated as:
public partial class _Resources_Index_cshtml :
System.Web.Mvc.WebViewPage<ConsoleApp.ModelClass> { ... }
Hope, there is some way to confgure the class globally for all views, without adding directives at the beginning of every .cshtml file.
It looks that that setting base view in web.config works in latest RazorGenerator.
So update your RazorGenerator package and try to have something like this in web.config:
<configSections>
<sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
<section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
<section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
</sectionGroup>
</configSections>
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="WebApplication2.Views.BaseView2">
<namespaces>
<add namespace="System.Web.Mvc" />

<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Optimization"/>
<add namespace="System.Web.Routing" />
</namespaces>
</pages>
</system.web.webPages.razor>
In my case I was adding precompilation (with RazorGenerator.Mvc and RazorGenerator.MsBuild packages) to old project and it didn't work. The problem was that I had Version=2.0.0.0 in my configSections project and had to change it to Version=3.0.0.0.
If someone finds it helpful, there is a nuget package for this by me. It is same Razorgenerator.MsBuild but with replacing System.Web.Mvc.WebViewPage by Custom.System.Web.Mvc.WebViewPage. So if you want to use custom WebViewPage, install the package and add you class named WebViewPage in namespace Custom.System.Web.Mvc. Like:
namespace Custom.System.Web.Mvc
{
public abstract class WebViewPage<T>
{
...
}
}
I have been scratching my head for days. I've googled to no avail. I am trying to get stuff from a database with jquery.ajax, based on the information I send over (sorta a post AND a get) everytime though, the server responds with an Error 404: Not Found, and is telling me I asked for Localhost:1986/undefined, which is not the case.
I'm sure exactly where all my folders and files are is important, so I will include as much as I can, feel free to ask for more if it is necessary.
My script is copy pasted and modified from another script I have to post to the database, and that works fine, so why this one doesn't stumps me:
function nextSlide() {
var articleLink = document.getElementsByTagName("a")[0];
$.ajax({
type: 'POST',
url: "../SlideShow/NextArticle",
data: {
slideID: articleLink.getAttribute("id"),
},
success: function (result) {
$(articleLink).id = result[0];
document.getElementById("articleImage").setAttribute("src", result[1]);
document.getElementById("articleTitle").innerHTML = result[2];
document.getElementById("articleText").innerHTML = result[3];
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("Status: " + textStatus); alert("Error: " + errorThrown);
}
});
}
This is the method inside my SlideShowController.cs file I am trying to use:
[AcceptVerbs(HttpVerbs.Post | HttpVerbs.Get)]
public JsonResult NextArticle(string slideID)
{
int ID = int.Parse(slideID);
var articles = db.Slides.ToList();
var currentArticle = db.Slides.First(s => s.SlideId == ID);
int articlePosition = articles.IndexOf(currentArticle);
articlePosition = (articlePosition + 1) >= articles.Count() ? 0 : articlePosition + 1;
var nextArticle = articles.ElementAt(articlePosition);
//nextArticle.Article.ArticleText.Substring(0, 50)+"..."
string[] returnParameters = {
nextArticle.SlideId.ToString(),
nextArticle.Image.ImageURL,
nextArticle.Article.ArticleTitle,
nextArticle.Article.ArticleText
};
return Json(returnParameters);
}
The SlideShowController.cs file is inside a folder named Controllers in the root directory. The script is called from a _SlideShowPartial.cshtml file in a Root/Views/SlideShow folder. That file is loaded in a Index.cshtml file in a Root/Views/Home folder using #html.Partial()
Here is a screenshot of the error that appears in chrome console:

You're definitely sending url wrongly to the server. try a complete url, or remove url from your $.ajax query.
Consider introducing T4 MVC into your project. This will give you strongly typed access to MVC actions and let you avoid URL strings which looks like your issue here.

My view is having issues finding a class located in one of my references.
This reference is to a dll built outside of the project.
The view always gives error:
The type or namespace name 'Company' could not be found (are you
missing a using directive or an assembly reference)
Here is the controller. No issues there.
using Company.Entities;
public ActionResult Find()
{
Person test = Person.SelectByADDistinguishedName("L*", false);
return View(test);
}
Here is the View. The error occurs in the #Model line.
#model Company.Entities.Person
#{
ViewBag.Title = "Bob";
}
<h2>Find</h2>
My Views/Web.config currently looks like this
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

I've checked similar threads like this one but to no avail.
Here is the message on the screen

If I strip out any mention of the assembly (out of web.config - no #using statments). I get the same error message when loaded but against this line
public class _Page_Views_Home_Find_cshtml : System.Web.Mvc.WebViewPage<Company.Entities.Person> {
After working it with it for awhile, I ended up solving it.
I had to add the assembly under the assemblies section of the main web.config (not the one under the views)
Sample of the web.config.
<compilation debug="true" targetFramework="4.0">
<assemblies>
<add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

<add assembly="Company, Version=2.0.31.0, Culture=neutral, PublicKeyToken=df9010405db60e6d"/>
</assemblies>
</compilation>
Thanks for people who gave me suggestions.
Be sure to check your views directory for an additional web.config file. I seem to remember running into a similar problem because I hadn't updated the correct web.config. YMMV.
Adding the reference
before where you use your control, in .cshtml file works. Example:
#model IEnumerable<MyApp.Models.MyModel>
#using System.Web.UI.WebControls;
But you can put it in web.config, under namespaces tag.
This way it is global to all views. Also, there is no need to specify the version:
<namespaces>
<add namespace="System.Web.UI.WebControls" />
</namespaces>
