CRUD Operations using MVC scaffolding with LINQ to SQL
In this article,I will show you CRUD operations using mvc scaffolding with linq to sql.
---Table Script---
create table Employee
(
id int primary key identity(1,1),
name varchar(50),
salary decimal(18,2)
)
Here must add package in project solution :
System.Data.Linq
---Model Class---
[Table]
public class Employee
{
[Column(IsPrimaryKey = true, IsDbGenerated = true)]
public int id { get; set; }
[Column]
public string name { get; set; }
[Column]
public decimal salary { get; set; }
}
---employee controller--
DataContext dc = new DataContext("Data Source=.;Initial Catalog=TESTDB;Integrated Security=True");
public ActionResult Index()
{
IEnumerable<Employee> emp_data = dc.GetTable<Employee>();
return View(emp_data);
}
public ActionResult Create()
{
return View();
}
[HttpPost]
public ActionResult Create(Employee emp)
{
dc.GetTable<Employee>().InsertOnSubmit(emp);
dc.SubmitChanges();
return RedirectToAction("Index");
}
[HttpGet]
public ActionResult Edit(int id)
{
Employee emp = dc.GetTable<Employee>().Single(x => x.id == id);
return View(emp);
}
[HttpPost]
public ActionResult Edit(Employee empobj)
{
Employee emp = dc.GetTable<Employee>().Single(x => x.id == empobj.id);
UpdateModel(emp);
dc.SubmitChanges();
return RedirectToAction("Index");
}
[HttpGet]
public ActionResult Delete(int id)
{
Employee emp = dc.GetTable<Employee>().Single(x => x.id == id);
return View(emp);
}
[HttpPost]
public ActionResult Delete(Employee empobj)
{
Employee emp = dc.GetTable<Employee>().Single(x => x.id == empobj.id);
dc.GetTable<Employee>().DeleteOnSubmit(emp);
dc.SubmitChanges();
return RedirectToAction("Index");
}
Note: Accoding to action method you can add scaffolding templet on view.
