By writing a view model:
public class UserViewModel
{
public string FirstName { get; set; }
public string LastName { get; set; }
}
Controller:
public class UsersController : Controller
{
public ActionResult Index()
{
return View(new UserViewModel());
}
[HttpPost]
public ActionResult Index(UserViewModel model)
{
// Here the default model binder will automatically
// instantiate the UserViewModel filled with the values
// coming from the form POST
return View(model);
}
}
View:
@model AppName.Models.UserViewModel
@using (Html.BeginForm())
{
<div>
@Html.LabelFor(x => x.FirstName)
@Html.TextBoxFor(x => x.FirstName)
</div>
<div>
@Html.LabelFor(x => x.LastName)
@Html.TextBoxFor(x => x.LastName)
</div>
<input type="submit" value="OK" />
}

Say for example if your view is strongly typed with a "Person" class:
public class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }
public int Age { get; set; }
}
Then inside your view:
@model MyMVCApp.Person
@using(Html.BeginForm())
{
@Html.EditorForModel()
// or Html.TextBoxFor(m => m.FirstName) .. and do this for all of the properties.
<input type="submit" value="Submit" />
}
Then you'd have an action that would handle the form:
[HttpPost]
public ActionResult Edit(Person model)
{
// do stuff with model here.
}
MVC uses what are called ModelBinders to take that form collection and map it to a model.
To answer your second question, you can refresh a page with the following JavaScript:
<script type="text/javascript">
// Reload after 1 minute.
setTimeout(function ()
{
window.location.reload();
}, 60000);
</script>
