public ActionResult Index(int requestid)
{
return View(db.RequestListDetails.Where(c=>c.RequestID == requestid).ToList());
}
How can I back to View(db.RequestListDetails.Where(c=>c.RequestID == requestid).ToList()); from Create action.
My Create action code like this
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "....")] RequestListDetail requestListDetail)
{
if (ModelState.IsValid)
{
db.RequestListDetails.Add(requestListDetail);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(requestListDetail);
}
After db.SaveChanges() you could use this:
return RedirectToAction("Index", new { requestid = requestListDetail.RequestId });

**Hello
I am developing an application with ASP.NET API, i created the controller entity and the MVC controllers that my generated CRUD operations in the view as follows (see picture), each operation in a file how to put it all in a single file.

Thank you in advance
I do not understand well what do you mean by "how to put it all in a single file"?
If you want to have all CRUD function in on 1 view, you can use jquery POST & GET.

I have a view named Register.cshtml and 2 partialview named _AddUser.cshtml And _UserList.cshtml.
When I run the project shows register.cshtml and _AddUser.cshtml load in view. I want to load _UserList partialview after success inserted in _AddUser partialview.
DefaultController:
public class DefaultController : Controller
{
UserRepository UR = new UserRepository();
Automation_DBEntities database = new Automation_DBEntities();
[HttpGet]
public ActionResult Register()
{
return View();
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Register(Users user, HttpPostedFileBase file)
{
UserRepository blUser = new UserRepository();
if (ModelState.IsValid)
{
///////////////////SaveImage
if (file != null)
{
if (user.UserImage != "no-photo.jpg")
{
if (System.IO.File.Exists(Server.MapPath("/image/UserImage/" + user.UserImage)))
System.IO.File.Delete(Server.MapPath("/image/UserImage/" + user.UserImage));
}
user.UserImage = Guid.NewGuid().ToString().Replace("-", "") + Path.GetExtension(file.FileName);
file.SaveAs(Server.MapPath("/image/UserImage/" + user.UserImage));
}
user.RegisterDate = DateTime.Now;
if (blUser.Add(user))
{
return PartialView("_UserList");//Inserted
}
else
{
}
}
else
{
}
}
[HttpGet]
public ActionResult AddUser()
{
return PartialView("~/Areas/Admin/Views/Shared/_AddUser.cshtml");
}
[HttpGet]
public ActionResult UserList()
{
IQueryable<AutomationSystem.Models.DomainModel.Users> list = UR.Select();
return PartialView("~/Areas/Admin/Views/Shared/_UserList.cshtml", list);
}
public class UserController : Controller
{
//
// GET: /User/
public ActionResult Register()
{
return View();
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Register(User U)
{
if (ModelState.IsValid)
{
using (MyDatabaseEntities dc = new MyDatabaseEntities())
{
dc.Users.Add(U);
dc.SaveChanges();
ModelState.Clear();
U = null;
ViewBag.Message = "Successfully register Done";
}
}
return View(U);
}
}
I suspect, but without the full error message giving us the type and location in the code it is something of a guess, that type User is protected or internal.
I have created an application in MVC 4 using Razor HTML. I have set up a model that has a few properties and my delete method which is posted below. This method works perfectly except for the fact that I don't want it to allow me to delete anything if one of the properties is not a certain number. How can i implement that in this method?
public ActionResult Delete(int id = 0)
{
Material material = db.Materials.Find(id);
if(material == null)
{
return HttpNotFound();
}
return View(material);
}
[HttpPost, ActionName("Delete")]
public ActionResult DeleteConfirmed(int id)
{
Material material = db.Materials.Find(id);
db.Materials.Remove(material);
db.SaveChanges();
return RedirecttoAction("Index");
}
In both your get and post actions, check the property and return an alternate "no delete allowed" view if the property you are checking doesn't have an allowable value.
public ActionResult Delete(int id = 0)
{
Material material = db.Materials.Find(id);
if(material == null)
{
return HttpNotFound();
}
else if (material.CheckedProperty != AllowableValue)
{
return View("DeleteNotAllowed", material);
}
return View(material);
}
[HttpPost, ActionName("Delete")]
public ActionResult DeleteConfirmed(int id)
{
Material material = db.Materials.Find(id);
if (material.CheckedProperty != AllowableValue)
{
return View("DeleteNotAllowed", material);
}
db.Materials.Remove(material);
db.SaveChanges();
return RedirecttoAction("Index");
}
Is it possible to return a string from controller upon a form submission ?
[HttpPost]
public ActionResult Index()
{
return Content("some string", "text/plain");
}
You can, as Darin suggest, return Content(string);
There are also other possibilities such as
[HttpPost]
public ActionResult Index(FormCollection form) {
/*
return Json(json);
return View;
return PartialView;
*/
}
If you return something other than an action result it will automatically be wrapped in a ContentResult.
[HttpPost]
public ContentResult Index(FormCollection form) {
/*
return Content(string);
return File(bytes, contentType);
return DateTime.Now;
return 2;
*/
}
public ActionResult Index()
{
// ...
return File(bytes, contentType);
}
