How to refresh the current page in MVC.
[HttpGet]
public ActionResult Request()
{
if (Session["type"] != null && Session["resulttype"] != null)
{
return View();
}
else
{
return null;
}
}
I want to refresh my page in else part. That is when return null value.
You can use Request.UrlReferrer.ToString()
[HttpGet]
public ActionResult Request()
{
if (Session["type"] != null && Session["resulttype"] != null)
return View();
else
return Redirect(Request.UrlReferrer.ToString());
}
You can use the following code in asp.net core
public IActionResult Index(){
return Redirect($"{Request.Path.ToString()}{Request.QueryString.Value.ToString()}");
}
Just Redirect to the Action you want to redirect to. It will refresh your page.
[HttpGet]
public ActionResult Request()
{
if (Session["type"] != null && Session["resulttype"] != null)
{
return View();
}
else
{
return RedirectToAction("Request");
}
}
You can use location.href = location.href; in Javascript code after calling a buttonclick or after a action method call like.
$('#btnme').click(function () {
location.href = location.href;
}

For some reason, The users in db.users.Where()is not working like the rest of the users in the code. Need some assistance to make it get to the logged in stage.
public ActionResult Login()
{
return View();
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Login(User users)
{
if (ModelState.IsValid)
{
using(DataContext db = new DataContext())
{
var obj = db.users.Where(u => u.Username.Equals(users.Username) && u.Password.Equals(users.Password)).FirstOrDefault();
if (obj != null)
{
Session["UserID"] = obj.UserID.ToString();
Session["Username"] = obj.Username.ToString();
return RedirectToAction("LoggedIn");
}
}
}
return View(users);
}
public ActionResult LoggedIn()
{
if (Session["UserID"] != null)
{
return View();
}
else
{
return RedirectToAction("Login");
}
}

The page i tried to print look like this:
But when i hit the button to print,in preview give me log in page:
AccountController:
protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
if (Session["CustomerID"] == null &! Request.RawUrl.ToLower().Contains("login"))
{
Response.Redirect("/Account/Login");
}
base.OnActionExecuting(filterContext);
}
<br>
//Login
public ActionResult Login()
{
return View();
}
[HttpPost]
public ActionResult Login(Customers cust)
{
using (DataContext db = new DataContext())
{
var user = db.Customers.Where(u => u.CustomerID == cust.CustomerID).FirstOrDefault();
if (user != null)
{
Session["CustomerID"] = user.CustomerID.ToString();
FormsAuthentication.SetAuthCookie(cust.CustomerID, false);
Session.Timeout = 30;
return RedirectToAction("LoggedIn");
}
else
{
ModelState.AddModelError("", "CustomerID is not Valid");
}
}
return View();
}
public ActionResult LoggedIn()
{
if (Session["CustomerID"] != null)
{
string customerId = Session["CustomerID"].ToString();
List<Orders> customerOrders;
using (DataContext data = new DataContext())
{
customerOrders = data.Orders.Where(x => x.CustomerID == customerId).ToList();
}
return View(customerOrders);
}
else
{
return RedirectToAction("Login");
}
}
public ActionResult Logout()
{
FormsAuthentication.SignOut();
Session.Remove("Login");
return RedirectToAction("Login", "Account");
}
public ActionResult PrintOrders(int id)
{
var report = new ActionAsPdf("ShowOrdersDetails", new { id = id });
return report;
}
In the 1st example:-
i am assigning User.Identity.Name value to the variable id. i am able to get the value after that i am Redirecting to some other view here i am using Redirect(ReturnUrl) now i am able to get the User.Identity.Name value in the other controller(Redirected view) also
But in the 2nd example :-
i am assigning User.Identity.Name value to the variable id i am able to get the value after that i am Redirecting to some other view here i am using return Redirect(ReturnUrl);when i am using return Redirect(ReturnUrl);am not able to get the User.Identity.Name value in the Redirected url
Example 1:-
public ActionResult SignIn(string ReturnUrl)
{
if (ReturnUrl == "/" || string.IsNullOrEmpty(ReturnUrl))
{
ReturnUrl = "/Dashboard";
}
var id=HttpContext.Current.User.Identity.Name;
Response.Redirect(ReturnUrl);
return View();
}
Example 2:-
public ActionResult SignIn(string ReturnUrl)
{
if (ReturnUrl == "/" || string.IsNullOrEmpty(ReturnUrl))
{
ReturnUrl = "/Dashboard";
}
var id=HttpContext.Current.User.Identity.Name;
return Redirect(ReturnUrl);
}
My Controller:- In this function if i am return Redirect(ReturnUrl); i am not able to get the User.Identity.Name value in CompanyRequired filter if i am using Response.Redirect(ReturnUrl); return View(); then able to get the User.Identity.Name value in CompanyRequired filter but i have to use return Redirect(ReturnUrl);
[HttpPost]
public async Task<ActionResult> SignInCallback()
{
var token = Request.Form["id_token"];
var state = Request.Form["state"];
var claims = await ValidateIdentityTokenAsync(token, state);
string ReturnUrl = state.Substring(state.IndexOf('?') + 1);
var id = new ClaimsIdentity(claims, "Cookies");
Request.GetOwinContext().Authentication.SignIn(id);
if (ReturnUrl == "/" || string.IsNullOrEmpty(ReturnUrl))
{
ReturnUrl = "/Dashboard";
}
var Id = User.Identity.Name;
return Redirect(ReturnUrl);
}
View:- Here i control will go to the CompanyRequired filter there i need a User.Identity.Name value in that i am getting value null
[Authorize,CompanyRequired]
public class DashBoardController : BaseController
{
public ActionResult Index()
{
return View();
}
}
CompanyRequired Filter:-
public class CompanyRequiredAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
var coCookie = filterContext.HttpContext.Request.Cookies["CoId"];
if (coCookie == null)
{
var Id= HttpContext.Current.User.Identity.Name.Int(); **//here i need to get the value but i am getting null value**
IdNmList cos = new EmployeeDAL().GetCompany(Id);
if (cos.Count == 0)
{
filterContext.Result = new RedirectToRouteResult(new System.Web.Routing.RouteValueDictionary
{
{ "controller" , "Company"},
{ "action" , "Add"}
});
}
else if (cos.Count == 1)
{
filterContext.HttpContext.Response.Cookies.Add(new HttpCookie("CoId", cos[0].Id.ToString()));
}
else
{
filterContext.Result = new RedirectToRouteResult(new System.Web.Routing.RouteValueDictionary
{
{ "controller", "Company" },
{ "action", "Select" },
{ "ReturnUrl", filterContext.HttpContext.Request.RawUrl }
});
}
}
base.OnActionExecuting(filterContext);
}
}
I have a controller that called "Login"
this method is in Login
public bool IsAuthenticated()
{
if (Session != null && Session["UserRole"] != null)
{
return true;
}
return false;
}
I set session values in Login other method.(ex: LogOn)
But in X Controller
public ActionsResult Index() {
if(!login.IsAuthenticated()){
return RedirectToAction("Index","Login");
}
return View();
}
in this method is null.
If I controll Session in Controller Methods,I think this isn't functional
public ActionsResult Index() {
if (Session == null && Session["UserRole"] == null)
{
return RedirectToAction("Index","Login");
}
return View();
}
Note:I don't Use ASP.net MVC Membership API
I have security in my MVC application set up with an authorize attribute...
public class UserLoggedInAttribute : AuthorizeAttribute
{
public override void OnAuthorization(AuthorizationContext filterContext)
{
if (filterContext.HttpContext.Session["UserId"] == null)
{
var values = new { controller = "Home", action = "Index" };
filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary(values));
}
}
}
Then I also have a .ashx HttpHandler which is called by jQuery upload control....
public class UploadFile : IHttpHandler, IReadOnlySessionState
{
...
private bool EnsureSecureTransaction(HttpContext context)
{
if (context.Session["UserId"] == null)
{
return false;
}
else
{
return true;
}
return true;
}
}
When EnsureSecureTransaction() gets called the session is coming back null. But session that is read in my MVC action its not. I notice that I'm taking session from the filterContext though.
I have tried to change all the code to try and reference HttpContext.Current.Session like this
[HttpPost]
public ActionResult Logon(AdminModel model)
{
if (model.UserName == "x" && model.Password == "x")
{
HttpContext.Session["UserId"] = "true";
return RedirectToAction("CreateBlog", "Blog");
}
return View;
}
private bool EnsureSecureTransaction(HttpContext context)
{
if (context.Session["UserId"] == null)
{
return false;
}
else
{
return true;
}
return true;
}
But basically when I hit the EnsureSecureTransaction() block its still saying my Session["UserId"] is null and therefor not autehenticating the call to the .ashx file correctly.
Anyone know why this is? Whats the actual difference between AuthorizationContext and HttpContext with regards to the session they carry and how do I get round this problem?
