Hi i want to save data which is enterd in partial view pop up window in Db.

Partial view Popup window

My controller

{

ViewBag.CityID = new SelectList(db.Cities, "CityID", "DisplayName");

return PartialView("ShowPartailView");

}

[HttpPost]

public ActionResult AddAreaInfo(Area area)

{

ViewBag.CityID = new SelectList(db.Cities, "CityID", "DisplayName");

bool isSuccess = false;

if (ModelState.IsValid)

{

area.DisplayName = area.DisplayName;

area.AreaID = Guid.NewGuid();

area.IsActive = true;

area. IsDeleted = false;

area.CreatedDate = DateTime.Now;

area.EditedDate = DateTime.Now;

area.LastActiveOn = DateTime.Now;

area.RowID = Guid.NewGuid();

area.CreatedSessionID = Guid.NewGuid();

area. EditedSessionID = Guid.NewGuid();

area.OfflineMode = false;

area.OfflineID = Guid.NewGuid();

db.Areas.Add(area);

db.SaveChanges();

}

return Json(new { result = isSuccess, responseText = "Something wrong!" });

}

My View

@Html.LabelFor(model => model.Area)

@Html.DropDownList("AreaID", null, "Select", new { @class = "form-control" })

My j queryCode

@using (Html.BeginForm("ShowPartailView", "Customer", "POST"))
