This article will illustrate how to insert record in SQL Server database using ADO.Net in ASP.Net MVC 5


In this article I will explain a tutorial with example, how to use ADO.Net in ASP.Net MVC 5.
This article will illustrate how to insert record in SQL Server database using ADO.Net in ASP.Net MVC 5.

Namespaces
You will need to import the following namespaces.
using System.Configuration;
using System.Data.SqlClient;
 
 
Model
Following is a Model class named CustomerModel with three properties i.e. CustomerId, Name and Country.
public class CustomerModel
{
    ///<summary>
    /// Gets or sets CustomerId.
    ///</summary>
    public int CustomerId { get; set; }
 
    ///<summary>
    /// Gets or sets Name.
    ///</summary>
    public string Name { get; set; }
 
    ///<summary>
    /// Gets or sets Country.
    ///</summary>
    public string Country { get; set; }
}
 
 
Controller
Then you will need to add a Controller class to your project. There are two Action methods with the name Index, one for handling the GET operation while other for handling the POST operation.
The Action method for POST operation accepts an object of the CustomerModel class as parameter. The values posted from the Form inside the View are received through this parameter.
The received values are then inserted into the SQL Server database table using ADO.Net. The CustomerId of the inserted record is fetched and assigned to the CustomerModelclass object which is then returned back to the View.
public class HomeController : Controller
{
    // GET: Home
    public ActionResult Index()
    {
        return View();
    }
 
    [HttpPost]
    public ActionResult Index(CustomerModel customer)
    {
        string constr = ConfigurationManager.ConnectionStrings["Constring"].ConnectionString;
        using (SqlConnection con = new SqlConnection(constr))
        {
            string query = "INSERT INTO Customers(Name, Country) VALUES(@Name, @Country)";
            query += " SELECT SCOPE_IDENTITY()";
            using (SqlCommand cmd = new SqlCommand(query))
            {
                cmd.Connection = con;
                con.Open();
                cmd.Parameters.AddWithValue("@Name", customer.Name);
                cmd.Parameters.AddWithValue("@Country", customer.Country);
                customer.CustomerId = Convert.ToInt32(cmd.ExecuteScalar());
                con.Close();
            }
        }
 
        return View(customer);
    }
}
 
Inside the View, in the very first line the CustomerModel class is declared as Model for the View.
The View consists of an HTML Form which has been created using the Html.BeginForm method with the following parameters.
ActionName – Name of the Action. In this case the name is Index.
ControllerName – Name of the Controller. In this case the name is Home.
FormMethod – It specifies the Form Method i.e. GET or POST. In this case it will be set to POST.
There is one TextBox field created for capturing value for Name using the Html.TextBoxFor method. While for capturing the Country value, a DropDownList with Country options is created using the Html.DropDownListFor function.
There’s also a Submit Button at the end of the Form and when the Button is clicked, the Form is submitted.
After the Form is submitted, the Model returned from the Controller is checked for NULL and if it is not NULL then the newly inserted CustomerId is displayed using JavaScript Alert MessageBox.
@model ADO_Net_MVC.Models.CustomerModel

    Layout = null;

Difference between each and map in jquery

Image
$.map $.each map method can be used as an iterator. each method is an immutable iterator Returns a new array Returns the original array The order of callback arguments - element, index. $.map(elems,  function  () { element, index }, arg) The order of callback arguments - index, element. $.each(elems,  function  () { index, element }, arg) Does not have a way to terminate the iteration Return false to terminate the iteration Example :  Notice that the callback arguments in the each method are the reverse of the callback arguments in the map function. Also notice that map returns a new array where as each method returns the original array. This proves the point that each method is an immutable iterator where as map is not. $(document).ready( function  () {      var  intArray = [1, 2, 3, 4, 5];      function  functionA(index, element) {          return ...
