Redirect Url After Form Submission

I have a basic form that allows a user to create an Employee. Once the user selects the submit button, the page should be redirected to a summary page. This summary page needs to show the details that were added on the Employee form.

For example, I have a form that looks like this:

enter image description here

Once the user selects Submit, it should then redirect the user to the following page:

enter image description here

The issue that I'm running into is getting that redirect url. My url looks something like: http://www.localhost.com/Employee/1234/ The 1234 represents the Employee id. How can I pull that Employee Id?

My Current HTML

<button type="submit" name="saveButton" id="saveBtn" class="btn btn-primary">Submit</button>

Please note that I am using .NET, so am open to using Razor Syntax.

Update on Story

After reading all of your comments, I went and dug deeper into my problem. This is what I found.

There is a RouteConfig.cs file with the following route:

routes.MapRoute(
  name: "ListEmployee",
  url: "Employee/{employeeId}",
  defaults: new { controller = "Employee", action = "List"},
  constraints: new {employeeId = "\\d+"}
)

Because I have this route, I decided to modify this controller method to utilize it:

[HttpPost]
public ActionResult AddEmployee(ViewModel<EmployeeModel> model)
{
  // logic here

  return RedirectToAction("ListEmployee", new { employeeId = model.Body.Employee.Id, fromEmployeeProject = true });
}

Issue: This completely crashes. Stating: No route in the route table matches the supplied values. Any ideas on what I am doing wrong?

If you're using Entity Framework (EF), it follows up each INSERT statement with SCOPE_IDENTITY() when auto-generated ids are used.

SCOPE_IDENTITY returns the last identity value inserted into an identity column in the same scope. (MSDN)

As such, if your Employee ID is an auto-generated column in the database, you should be able to get the ID right after saving your changes:

[HttpPost]
public ActionResult Add(Employee employee)
{
    using (var context = new MyContext())
    {
        // add the employee object
        context.Employees.Add(employee);
        // save changes
        context.SaveChanges();
        // the id will be available here
        int employeeId = employee.Id;   
        // ..so perform your Redirect to the appropriate action, _
        // and pass employee.Id as a parameter to the action       
        return RedirectToAction("Index", "Employee", new { id = employeeId });            
    }
}

Obviously you haven't provided us with your controller and action names so make sure that you replace them with the appropriate values.

To get the id you can, in your view, add an input type hidden:

<input type="hidden" name="id" value="[value]" />

in your controller:

[HttpPost]
public ActionResult [ActionName] (int id)
{
.....
employeeRepository.Save(employee);
return RedirectToAction("Summary", new {id});
}

and in your action Summary:

public ActionResult Summary(int id)
{
.....
}

One of the most common way of doing it is to return different View from your Action that you call from Employee Form. For instance let say your Employee Forms calls EmployeeController->Add(Employee employee) action

Inside of your Employee Action you will have something like this:

[HttpPost]
public ActionResult Add(Employee employee)
{
    // process request and create new employee in repository

    return View("Summary");
}

Another way of doing it is to call RedirectToAction(), this is similar to Response.Redirect() in ASP.NET WebForms.

[HttpPost]
public ActionResult Add(Employee employee)
{
    // process request and create new employee in repository

    return RedirectToAction("Summary");
}

You can allso call Redirect method. This will cause the browser to receive 302 error and redirect to your controller/action specified

[HttpPost]
public ActionResult Add(Employee employee)
{
    // process request and create new employee in repository

    return Redirect("YourController/Summary");
}
