How to Insert and Update two tables using Entity Framework with ASP.NET MVC4
I am create a demo application with ASP.NET MVC4 with these two tables:
Table tblCustomerInformation :
CREATE TABLE [dbo].[tblCustomerInformation]
(
[CustomerID] [int] NOT NULL,
[CustomerName] [varchar](200) NULL,
[CustomerFatherName] [varchar](200) NULL,
[CustomerMotherName] [varchar](200) NULL,
[CustomerAge] [int] NULL,
CONSTRAINT [PK_tblCustomerInformation] PRIMARY KEY CLUSTERED ([CustomerID] ASC)
)
Table tblCustomerContact :
CREATE TABLE [dbo].[tblCustomerContact]
(
[CustomerId] [int] NOT NULL,
[CustomerContactId] [int] NOT NULL,
[CustomerAddress] [varchar](100) NULL,
[CustomerContactNumber] [varchar](20) NULL,
[CustomerPinCode] [varchar](10) NULL,
CONSTRAINT [PK_tblCustomerContact] PRIMARY KEY CLUSTERED ([CustomerContactId] ASC)
)
ALTER TABLE [dbo].[tblCustomerContact] WITH CHECK
ADD CONSTRAINT [FK_tblCustomerContact_tblCustomerInformation]
FOREIGN KEY([CustomerId]) REFERENCES [dbo].[tblCustomerInformation] ([CustomerID])
Note : these tables have a one-to-many relationship
And I have views for Details, Edit and Insert and have also a partial view which is use for helping me insert the second table data ( tblCustomerContact ) (This partial view is use in Index page)
After that create a MVC project and then add an ADO.Net Entity Data Model with named NewCustomerInformation.edmx and map the stored procedure.
Controller Code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using MvcStoredProcedureApp.Models;
using System.Data;
using System.Data.Entity.Infrastructure;
namespace MvcStoredProcedureApp.Controllers
{
public class HomeController : Controller
{
//
// GET: /Home/
NewCutomerInformationEntities _custmerInformationEntities = new NewCutomerInformationEntities();
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult Index(tblCustomerInformation tblCustomerInfo, tblCustomerContact tblCustomerCon)
{
tblCustomerInformation tblCustomerQuery = _custmerInformationEntities.tblCustomerInformations.Find(tblCustomerInfo.CustomerID);
if (tblCustomerQuery == null)
{
_custmerInformationEntities.tblCustomerInformations.Add(tblCustomerInfo);
_custmerInformationEntities.SaveChanges();
_custmerInformationEntities.tblCustomerContacts.Add(tblCustomerCon);
_custmerInformationEntities.SaveChanges();
}
else
{
_custmerInformationEntities.Entry(tblCustomerQuery).CurrentValues.SetValues(tblCustomerInfo); _custmerInformationEntities.SaveChanges(); _custmerInformationEntities.Entry(tblCustomerInfo).State = EntityState.Modified; _custmerInformationEntities.SaveChanges(); tblCustomerContact tblCust = new tblCustomerContact(); } return View(); }
public ActionResult getList()
{
return View(_custmerInformationEntities.tblCustomerInformations);
}
public ActionResult Edit(int id = 0)
{
tblCustomerInformation _tblCustomerInformation = _custmerInformationEntities.tblCustomerInformations.Find(id);
tblCustomerContact tblCont = _custmerInformationEntities.tblCustomerContacts.Single(p => p.CustomerId == id);
return View(_tblCustomerInformation);
}
}
}
Index
@model MvcStoredProcedureApp.Models.tblCustomerInformation
@{
ViewBag.Title = "Index";
}
<h2>Index</h2>
@using (Html.BeginForm("Index", "Home", null, FormMethod.Post, new { @id = "EntryForm" }))
{
<table>
<tr>
<td>@Html.Label("Customer Id::")</td>
<td>@Html.TextBoxFor(m=>m.CustomerID)</td>

}

}
Partial View _CustomerContact
@model MvcStoredProcedureApp.Models.tblCustomerContact
<table>
<tr>
<td>@Html.Label("Contact ID")</td>
<td>@Html.TextBoxFor(m => m.CustomerContactId)</td>

<tr>
<td>@Html.Label("Contact Number")</td>

<tr>
<td>@Html.Label("Customer Address")</td>
<td>@Html.TextBoxFor(m => m.CustomerAddress)</td>
</tr>
<tr>
<td>@Html.Label("Pin-Code")</td>
<td>@Html.TextBoxFor(m => m.CustomerPinCode)</td>
</tr>
</table>
My problem is that when I am trying to insert it will work fine but when trying to update my table it will not update. Please help I am new to ASP.NET MVC.
Thanks!
如果要更新数据库中的记录，则必须在编辑视图中将contractid作为隐藏键传递。
