Create (Add) ActionLink Column to WebGrid in ASP.Net MVC


The ActionLink Column will be created in WebGrid using Html.ActionLink Helper method in ASP.Net MVC Razor.

The ActionLink Column in WebGrid when clicked, will send the details of the WebGrid row to another View in ASP.Net MVC Razor


Controller
The Controller consists of two Action methods.
Action method for handling GET operation of Index View
The Entity Framework is now configured and hence now we can create a Controller and write code to fetch the records from the Customers Table of the Northwind Database.
Inside the Index Action method, the Customer records are fetched using Entity Framework and returned to the View.
 
Action method for handling GET operation of Details View
Inside this Action method, the value of the CustomerId is fetched from the RouteData collection and is used to fetch the Customer’s record using Entity Framework.
Finally the Customer’s record is returned to the View.
public class HomeController : Controller
{
    // GET: Home
    public ActionResult Index()
    {
        NorthwindEntities entities = new NorthwindEntities();
        return View(entities.Customers.ToList());
    }
 
    public ActionResult Details()
    {
        string customerId = RouteData.Values["id"].ToString();
        NorthwindEntities entities = new NorthwindEntities();
        return View(entities.Customers.Find(customerId));
    }
}
 
 
Index View
Inside the Index View, in the very first line the Customer Entity is declared as IEnumerable which specifies that the Model will be available as a Collection.
The WebGrid is initialized with the Model i.e. IEnumerable collection of Customer Entity class objects as source.
The WebGrid is created using the GetHtml method with the following parameters.
HtmlAttributes – It is used to set the HTML attributes to the HTML Table generated by WebGrid such as ID, Name, Class, etc.
Columns – It is used to specify the columns to be displayed in WebGrid and also allows to set specific Header Text for the columns.
The first column of the WebGrid consists of an ActionLink created using Html.ActionLink Helper method.
When the ActionLink is clicked redirects to the Details View.
@model IEnumerable<WebGrid_ActionLink_MVC.Customer>
 
@{
    Layout = null;
    WebGrid webGrid = new WebGrid(source: Model, canSort: false);
}
 
<!DOCTYPE html>
 
<html>
<head>
    <meta name="viewport" content="width=device-width"/>
    <title>Index</title>
    <style type="text/css">
        body
        {
            font-family: Arial;
            font-size: 10pt;
        }
 
        .Grid
        {
            border: 1px solid #ccc;
            border-collapse: collapse;
        }
 
        .Grid th
        {
            background-color: #F7F7F7;
            font-weight: bold;
        }
 
        .Grid th, .Grid td
        {
            padding: 5px;
            border: 1px solid #ccc;
        }
 
        .Grid, .Grid table td
        {
            border: 0px solid #ccc;
        }
 
        .Grid th a, .Grid th a:visited
        {
            color: #333;
        }
    </style>
</head>
<body>
    @webGrid.GetHtml(
        htmlAttributes: new { @id = "WebGrid", @class = "Grid" },
        columns: webGrid.Columns(
                 webGrid.Column("CustomerID", "Customer Id", format: @<text> @Html.ActionLink(linkText: (string)@item.CustomerID, actionName: "Details", routeValues: new { id = item.CustomerID })</text>),
                 webGrid.Column("ContactName", "Customer Name"),
                 webGrid.Column("City", "City"),
                 webGrid.Column("Country", "Country")
      ))
</body>
</html>
 
 
Details View
Inside the Details View, in the very first line the Customer Entity is declared as Model for the View. The details of the Customer is displayed using the Html.DisplayFor helper method.
@model WebGrid_ActionLink_MVC.Customer
 
@{
    Layout = null;
}
 
<!DOCTYPE html>
<html>
<head>
    <meta name="viewport" content="width=device-width"/>
    <title>Details</title>
    <style type="text/css">
        body
        {
            font-family: Arial;
            font-size: 10pt;
        }
    </style>
</head>
<body>
    <table cellpadding="0" cellspacing="0" border="0">
        <tr>
            <td valign="top" style="width:65px"><b>@Html.DisplayNameFor(model => model.Address):</b></td>
            <td>
                @Html.DisplayFor(model => model.Address)
                <br/>
                @Html.DisplayFor(model => model.City),
                @Html.DisplayFor(model => model.PostalCode)
                <br/>
                @Html.DisplayFor(model => model.Country)
            </td>
        </tr>
    </table>
</body>
</html>
 
 
Mapping Routes for the Details View
You will need to map a route for the Details View by making use of the MapRoute function as shown below.
This is necessary as otherwise the Routing won’t work for the Details View when the ActionLink in WebGrid is clicked.
public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
 
        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
 
        routes.MapRoute(
            name: "Details",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Details", id = UrlParameter.Optional }
        );
    }
}

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 ...
