Next Go to Model and create a class.
Give the name of the class as Employee.cs
Employees.cs
public class Employees
{
public int? Eno { get; set; }
public string Ename { get; set; }
public string Address { get; set; }
public List<Employees> GetAllEmployees()
{
DataTable objTbl = new DataTable();
List<Employees> employeeList = newSystem.Collections.Generic.List<Employees>();
SqlConnection objCon = new SqlConnection();
objCon.ConnectionString = "";
SqlDataAdapter objAdp = new SqlDataAdapter("select * from employees", objCon);
objAdp.Fill(objTbl);
foreach (DataRow dr in objTbl.Rows)
{
employeeList.Add(new Employee()
{
Eno = Convert.ToInt32(dr["ENO"]),
Ename = Convert.ToString(dr["Ename"]),
Address = Convert.ToString(dr["Address"])
});
}
return employeeList;
}
}
Now the model is ready.
Next go to controller.
Add->Controller
And write the following code
Right click on the page
Select Add View
Now the view is created.
And run the application to test the summary Page.
To create:
Write the following lines of code in Employee Controller
Again write click on the controller

And click on Create New.
And again write the following lines of code in Employee Controller
[HttpPost]
public ActionResult Create(Employees obj)
{
Employees objemp = new Employees();
objemp.SaveEmployeeDetails(obj);
return RedirectToAction("Employee");
}
And write the following code in Employees.cs
And write the following code in Employees.cs
public void SaveEmployeeDetails(Employees obj)
{
SqlConnection objCon = new SqlConnection();
objCon.ConnectionString = "";
SqlCommand cmd = new SqlCommand();
cmd.CommandText = "insert into Employees(Eno,Ename,Address) values(" + obj.Eno + ",'"+ obj.Ename + "','" + obj.Address + "')";
objCon.Open();
cmd.Connection = objCon;
cmd.CommandType = CommandType.Text;
cmd.ExecuteNonQuery();
objCon.Close();
}
Details:
Now go to Employee.cshtml (View Folder)
And modify the following lines of code.
@Html.ActionLink("Details", "Details", new { id=item.Eno })
Here Eno is the primary key of my table.
Go to Employee controller.cs
public ActionResult Details(int id)
{
Employees obj = Employees.GetEmployeesById(id);
if (obj == null)
{
return HttpNotFound();
}
return View(obj);
}
Go to Employees.cs and write the following code.
public static Employees GetEmployeesById(int Eno)
{
DataTable objTbl = new DataTable();
SqlConnection objCon = new SqlConnection();
objCon.ConnectionString = "";
SqlDataAdapter objAdp = new SqlDataAdapter("select * from employees where eno =" + Eno, objCon);
objAdp.Fill(objTbl);
Employees objEmployees = new Employees() { Eno = Convert.ToInt32(objTbl.Rows[0]["Eno"]), Ename = Convert.ToString(objTbl.Rows[0]["Ename"]), Address = Convert.ToString(objTbl.Rows[0]["Address"]) };
return objEmployees;
}
And right click on the Employee Controller and select Add View
Edit
Employee.cshtml
@Html.ActionLink("Details", "Details", new { id=item.Eno })
Go to Employee Controller and write the following Code
[HttpGet]
public ActionResult Edit(int id)
{
Employees obj = Employees.GetEmployeesById(id);
if (obj == null)
{
return HttpNotFound();
}
return View(obj);
}
Again Right Click on the Employee Controller and Add View
And click on Add Button.
And test the application.
And click on Edit Button.
Again go to Employee Controller.cs and write the following code to save the modified values.
[HttpPost]
public ActionResult Edit(Employees obj)
{
Employees objemp = new Employees();
objemp.UpdateEmployeeDetails(obj);
return RedirectToAction("Employee");
}
Employees.cs and write the following code
Now update the values and check the summary page.
Delete
Goto Employee.cshtml and modified the following code .
@Html.ActionLink("Edit", "Edit", new { id=item.Eno }) |
@Html.ActionLink("Details", "Details", new{ id=item.Eno }) |
@Html.ActionLink("Delete", "Delete", new { id=item.Eno })
Then go to EmployeeController.cs and write the following code in it.
public ActionResult Delete(int id)
{
Employees objemp = new Employees();
objemp.DeleteEmployeeDetails(id);
return RedirectToAction("Employee");
}
Go To Employee.cs and write the following code.
Points to Remember
Here int id in the parameter should be same as
@Html.ActionLink("Details", "Details", new { id=item.Eno })
Both the names should be same
