C# ASP.NET MVC Forms Creating a Basic Form Adding a POST Action Method

ASP.NET MVC FORMS

I can't figure out what I'm doing wrong.

Link: https://teamtreehouse.com/library/aspnet-mvc-forms/creating-a-basic-form/adding-a-post-action-method

Question:

Challenge Task 1 of 1

In IssuesController.cs add another action method named Report to handle HTTP posts from the form in the Report.cshtml view.

    Decorate the action method with an attribute so that MVC will only route POST requests to it.
    Add a total of six parameters that match the form field names in the Report.cshtml view file in order to capture posted values from the form. Remember to change the first letter of each form field to lowercase (i.e. "Name" to "name").
    Use the string data type for each parameter.
    For now, in the action method, just return a call to the View method.

IssuesController.cs file

using System.Web.Mvc;

namespace IssueReporter.Controllers
{
    public class IssuesController : Controller
    {
        public ActionResult Report()
        {
            return View();
        }
    }
}

Report.cshtml file:

@{
    ViewBag.Title = "Report an Issue";
}

<h2>@ViewBag.Title</h2>

<form method="post">

    <div>
        <label for="Name">Name</label>
        <input type="text" id="Name" name="Name" />
    </div>

    <div>
        <label for="Email">Email</label>
        <input type="text" id="Email" name="Email" />
    </div>

    <div>
        <label for="DepartmentId">Department</label>
        <input type="text" id="DepartmentId" name="DepartmentId" />
    </div>

    <div>
        <label for="Severity">Severity</label>
        <input type="text" id="Severity" name="Severity" />
    </div>

    <div>
        <label for="Reproducible">Reproducible</label>
        <input type="text" id="Reproducible" name="Reproducible" />
    </div>

    <div>
        <label for="DescriptionOfProblem">Description of Problem</label>
        <textarea id="DescriptionOfProblem" name="DescriptionOfProblem"></textarea>
    </div>

    <button type="submit">Save</button>

</form>

One of my answers:

IssuesController.cs:

using System.Web.Mvc;

namespace IssueReporter.Controllers { public class IssuesController : Controller { public ActionResult Report() {
return View(); }

    [HttpPost]
    public ActionResult Add(string name, string email, 
    string departmentId, string severity, string reproducible, 
    string descriptionofproblem)  

    {
    viewBag.Name = name;
    viewBag.Email = email;
    viewBag.DepartmentId = departmentId;
    viewBag.Severity = severity;
    viewBag.Reproducible = reproducible;

    return View();
    }
}

}

Report.cshtml

@{ ViewBag.Title = "Report an Issue"; }

<h2>@ViewBag.Title</h2>

<form method="post">

<div>
    <label for="Name">Name</label>
    <input type="text" id="Name" name="Name" value="@viewBag.Name" />
</div>

<div>
    <label for="Email">Email</label>
    <input type="text" id="Email" name="Email" value="@viewBag.Email" />
</div>

<div>
    <label for="departmentId">Department</label>
    <input type="text" id="DepartmentId" name="DepartmentId" value="@viewBag.DepartmentId" />
</div>

<div>
    <label for="severity">Severity</label>
    <input type="text" id="Severity" name="Severity" value="@viewBag.Severity" />
</div>

<div>
    <label for="reproducible">Reproducible</label>
    <input type="text" id="Reproducible" name="Reproducible" value="@viewBag.Reproducible" />
</div>

<div>
    <label for="descriptionOfProblem">Description of Problem</label>
    <textarea id="DescriptionOfProblem" name="DescriptionOfProblem"> </textarea>
</div>

<button type="submit">Save</button>

</form>

I've followed the video 4-5 times now, it's not working for me.

```IssuesController.cs
using System.Web.Mvc;

namespace IssueReporter.Controllers
{
    public class IssuesController : Controller
    {
        public ActionResult Report()
        {      
            return View();
        }

        [HttpPost]
        public ActionResult Add(string name, string email, 
        string departmentId, string severity, string reproducible, 
        string descriptionofproblem)  

        {
           return View();
        }
    }
}
Report.cshtml 
@{
    ViewBag.Title = "Report an Issue";
}

<h2>@ViewBag.Title</h2>

<form method="post">

    <div>
        <label for="Name">Name</label>
        <input type="text" id="Name" name="Name" />
    </div>

    <div>
        <label for="Email">Email</label>
        <input type="text" id="Email" name="Email" />
    </div>

    <div>
        <label for="DepartmentId">Department</label>
        <input type="text" id="DepartmentId" name="DepartmentId" />
    </div>

    <div>
        <label for="Severity">Severity</label>
        <input type="text" id="Severity" name="Severity" />
    </div>

    <div>
        <label for="Reproducible">Reproducible</label>
        <input type="text" id="Reproducible" name="Reproducible" />
    </div>

    <div>
        <label for="DescriptionOfProblem">Description of Problem</label>
        <textarea id="DescriptionOfProblem" name="DescriptionOfProblem"></textarea>
    </div>

    <button type="submit">Save</button>

</form>

Larry,

Are you getting an error message? Also, remembering that C# is a case sensitive language, double check the casing of your action method parameter names.

Thanks ~James

Larry,

Ah... that helps. The property name is actually ViewBag not viewBag.

https://msdn.microsoft.com/en-us/library/system.web.mvc.controllerbase.viewbag(v=vs.118).aspx

Try making that change and see what error happens next :)

Thanks ~James

Breaking it down to one step at a time, I have this now in the IssuesController.cs file

using System.Web.Mvc;

namespace IssueReporter.Controllers
{
    public class IssuesController : Controller
    {
        public ActionResult Report()
        {      
            return View();
        }

            [HttpPost]
        public ActionResult Add(string name, string email, 
        string departmentId, string severity, string reproducible, 
        string descriptionofproblem)  
        { 

        ViewBag.Date = name;
        ViewBag.Email = email;
        ViewBag.DepartmentId = departmentId;
        ViewBag.Severity = severity;
        ViewBag.Reproducible = reproducible;



        return View();
        }
    }
}

It's giving me this error:

Bummer! Did you declare a method named Report in IssuesController?

I'm not seeing the problem. I've left the report.cshtml file to its unaltered original state and will work on it when I get the IssuesController.cs file fixed. I stepped away from this to hopefully give me enough time to undo any brain farts that may be going on. Tonight I will watch the videos again and put more effort into it.

Again, thanks for responding, Larry
