I'm using Elmah to log exceptions, and have been going nuts due to customers complaining about getting errors, but I don't see any 500s in Elmah's log.
The exceptions are occurring inside some attributes on model properties, when the model is being validated. Obviously there's something wrong with my validation which I can fix, but I'd still really like Elmah to log these things if (when) they come up again.

I am trying to use Aspnet with Roles. With the NRE, still I cannot figure out what to instantiate.
This is in the controller
[Authorize(Roles = "Admin")]
public ActionResult ForAdmin()
{
return View();
}
This is how I authorize
public Programmer GetLoginCredentials(Login credential)
{
Programmer programmer = null;
HttpContext.Current.Session["ProgrammerName"] = null;
HttpContext.Current.Session["Roles"] = null;
using (
var cmd = new SqlCommand("Sp_GetLoginCredentials", _dbConnection)
{
CommandType = CommandType.StoredProcedure
})
{
try
{
cmd.Parameters.AddWithValue("#Username", credential.Username);
cmd.Parameters.AddWithValue("#Password", credential.Password);
var da = new SqlDataAdapter(cmd);
var ds = new DataSet();
da.Fill(ds);
if (ds.Tables[0].Rows.Count <= 0) return null;
foreach (DataRow row in ds.Tables[0].Rows)
{
programmer = new Programmer()
{
ProgrammerId = Convert.ToInt32(row["ProgrammerId"]),
ProgrammerName = row["ProgrammerName"].ToString(),
Username = row["Username"].ToString(),
Password = row["Password"].ToString()
};
HttpContext.Current.Session["ProgrammerName"] = programmer.ProgrammerName;
}
if (programmer != null)
{
GetRoles(programmer);
}
return programmer;
}
catch
{
return null;
}
}
}
This is how I fill the session with roles
public List<Role> GetRoles(Programmer credential)
{
var roleList = new List<Role>();
using (var cmd = new SqlCommand("Sp_GetRoles", _dbConnection) {CommandType = CommandType.StoredProcedure})
{
cmd.Parameters.AddWithValue("#Username", credential.Username);
cmd.Parameters.AddWithValue("#Password", credential.Password);
var da = new SqlDataAdapter(cmd);
var ds = new DataSet();
da.Fill(ds);
if (ds.Tables[0].Rows.Count > 0)
{
roleList.AddRange(from DataRow row in ds.Tables[0].Rows
select new Role()
{
RoleName = row["RoleName"].ToString()
});
}
HttpContext.Current.Session["Roles"] = roleList;
}
return roleList;
}
This is my role provider
public class SiteRole : RoleProvider
{
public override string[] GetRolesForUser(string username)
{
var data = HttpContext.Current.Session["Roles"];
return data as string[];
}
}
In my Session["Roles"] I get it like this
So that means I am able to get the "Admin" role but in my browser, I get this error:

Can you please show me where I am getting it wrong? Thank you.
You cannot cast HttpContext.Current.Session["Roles"] to string[] because it's of type List<Role>
Try this instead:
public override string[] GetRolesForUser(string username)
{
var data = HttpContext.Current.Session["Roles"] as IEnumerable<Role>;
return data.Select(d => d.RoleName).ToArray();
}
I am trying to render a partial view in Umbraco. I have a BaseLayout.cshtml,Homepage.cshtml,BaseLayoutViewModel,HomepageViewModel
This is my BaseLayout View
#inherits Umbraco.Web.Mvc.UmbracoViewPage<View_Models.BaseLayoutViewModel>
#{
Layout = null;
}
<!DOCTYPE html>
<html lang="en-gb">
<head>
</head>
<body>
#Html.Action("GetPrimaryNavbar", "PrimaryNavbar", Model) //This is there the site throws an error.
#RenderBody()
</body>
</html>
This is my BaseLayout Model. Homepage model inherits from base layout.
public class BaseLayoutViewModel : PublishedContentModel
{
public BaseLayoutViewModel(IPublishedContent content) : base(content)
{
}
public string PageTitle => this.GetPropertyValue<string>(FieldNames.BaseLayout.PageTitle);
public string PageDescription => this.GetPropertyValue<string>(FieldNames.BaseLayout.PageDescription);
public string NavigationName => this.GetPropertyValue<string>(FieldNames.BaseLayout.NavigationName);
}
My PrimaryNavbar Partial view is:
#inherits Umbraco.Web.Mvc.UmbracoViewPage<View_Models.PrimaryNavbarViewModel>
<header>
<ul>
<li>
</li
</ul>
</header>
And the controller for the PrimaryNavbar is:
public class PrimaryNavbarController : SurfaceController
{
[ChildActionOnly]
public ActionResult GetPrimaryNavbar(RenderModel model)
{
//var primaryNavbarViewModel = new PrimaryNavbarViewModel(model.Content);
return PartialView("PrimaryNavbar");//, primaryNavbarViewModel);
}
}

I cant understand why I am getting "No parameterless constructor defined for this object." Can someone help me on this?
Thanks
To solve the issue you need to send the model like this:
#Html.Action("GetPrimaryNavbar", "PrimaryNavbar", new { model = Model })
i have this model :
[Required(ErrorMessage = "This field is required")]
public byte[] passportImage { get; set; }
also i have this view:
<div class="editor-label">
#Html.LabelFor(model => model.passportImage)
</div>
<div class="editor-field">
#Html.TextBoxFor(model => model.passportImage, new { placeholder = "Uploadt Your Passport", type = "file"})
#Html.ValidationMessageFor(model => model.passportImage)
</div>
when i submit the form to the controller, i got this excpetion:
The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters.

I know it is something with image, bytes and base64, but please who could i solve that ?
Change model to
[Required(ErrorMessage = "This field is required")]
public HttpPostedFileBase passportImage { get; set; }
If you want byte array you can convert input stream
byte[] image = new byte[model.passportImage.ContentLength];
model.passportImage.InputStream.Read(image, 0, image.Length);
I've been stuck trying to debug this issue. I believe the error Is occurring when I am trying to populate a drop down list.
IEnumerable<Customer> values = db.Customers.SqlQuery("SELECT * FROM Customer").ToList().Cast<Customer>();
IEnumerable<SelectListItem> items =
from value in values
select new SelectListItem
{
Text = value.CustomerID.ToString(),
Value = value.CustomerID.ToString(),
};
ViewBag.Accounts = items;

Judging from the exception message your Customer class looks something like this...
public class Customer
{
[StringLength(4)]
public int CustomerID { get; set;}
}
Notice that you can't use StringLength on an int property.
Get rid of the StringLength and the validation exceptions should go away.
