I have tried simple user log in using asp.net mvc4. I have used this condition (ModelState.IsValid), It was workiing before two days. Now i am trying to execute this program, But that property is terminating the condition. Please anyone help me to rectify this problem. This is my controller code {
[HttpPost]
[AllowAnonymous]
public ActionResult LogIn(Project.Models.Tbl_Users user)
{
int userid = user.UserID;
var sessionid = Session["userid"];
Session["RoleId"] = user.RoleId;
Session["Username"] = user.UserName;
var sessionval = Session["Username"].ToString();
if (!ModelState.IsValid)
{
if (Isvalid(user.UserName, user.UserPassword))
{
var db = new Project.Models.EntitiesContext();
var userroleid = db.Tbl_Users.FirstOrDefault(u => u.UserName == user.UserName);
Session["RoleId"] = userroleid.RoleId;
int sessionroleid = Convert.ToInt32(Session["RoleId"]);
FormsAuthentication.SetAuthCookie(user.UserName, false);
string sessionusername = Session["Username"].ToString();
if (sessionroleid == 1)
{
return RedirectToAction("adminpage", "LogIn");
}
else
if(sessionroleid==2)
{
return RedirectToAction("teammanager", "LogIn");
}
else
{
return RedirectToAction("userpage", "LogIn");
}
}
return View(sessionval);
}
return View();
}
private bool Isvalid(string username, string password)
{
bool Isvalid = false;
using(var db = new Project.Models.EntitiesContext())
{
var user = db.Tbl_Users.FirstOrDefault(u => u.UserName == username);
var pass = db.Tbl_Users.FirstOrDefault(u => u.UserPassword == password);
if (username != null)
{
try
{
if (user.UserName == username)
{
if (pass.UserPassword == password)
{
Isvalid = true;
//Session["RoleId"] = user.RoleId;
//int sessionid = Convert.ToInt32(Session["RoleId"]);
}
}
}
catch
{
//Response.Write("Login Failed For The User");
Isvalid = false;
}
}
}
} This is my model {
[Required(ErrorMessage = "User Name is Invalid")]
[StringLength(200)]
[Display(Name = "User Name")]
public string UserName { get; set; }
[Required(ErrorMessage = "Password Field is Invalid")]
[StringLength(50, MinimumLength = 6)]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string UserPassword { get; set; }
[Display(Name = "Remember me?")]
public bool RememberMe { get; set; }
}
This is my view code {
<form method="post" id="signin" action="@Url.Action("LogIn", "LogIn")">
<body style="background-color: Gray;">
<div>
<div>
</div>
@if (!Request.IsAuthenticated)
{
<strong>@Html.Encode(User.Identity.Name)</strong>
@Html.ActionLink("Log Out", "LogOut", "LogIn")
}
else
{
<fieldset>
<div>@Html.LabelFor(u => u.UserName)</div>
<div>@Html.TextBoxFor(u => u.UserName)
@if (Request.IsAuthenticated)
{
@Html.ValidationMessageFor(u => u.UserName)
@*@Html Session["Username"] = @Html.TextBoxFor(u => u.UserName);*@
}
</div>
<div>@Html.LabelFor(u => u.UserPassword)</div>
<div>@Html.PasswordFor(u => u.UserPassword)
@Html.ValidationMessageFor(u => u.UserPassword)
</div>
<div>@Html.CheckBoxFor(u => u.RememberMe)
@Html.LabelFor(u => u.RememberMe, new { @class = "checkbox" })
</div>
<div>
@Html.ValidationSummary(true, "Login Failed")
</div>
<input type="submit" value="LogIn"/>
</fieldset>
}
</div>
</body>
</form>
}
