This topic describes how to add a MultiRow control to your MVC application and populate data in it. The below example demonstrates how to achieve local model binding in MultiRow control. You can also perform remote data binding in MultiRow control, for more information, see Remote Data Binding.

This topic comprises following three steps:

• Step 1: Create a Datasource for MultiRow
• Step 2: Add a MultiRow Control
• Step 3: Build and Run the Project

The following image shows how MultiRow control appears after completing the steps:

Step 1: Create a Datasource for MultiRow

1. Add a new class to the Models folder (for example: Orders.cs). For more information on how to add a new model, see Adding Controls.
2. Add the following code to Orders.cs model. We are using Orders class to represent sales order data in the database. Each instance of Orders object will correspond to a record in MultiRow control.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace MultiRow.Models
{
    public class Orders
    {
        private static object _lockObj = new object();
        private static Random Rand = new Random();
        private static IList<Order> _orders;
        private static IList<string> _cities;
        private static IList<Customer> _customers;
        public class Customer
        {
            public int Id { get; set; }
            public string Name { get; set; }
            public string Address { get; set; }
            public string City { get; set; }
            public string State { get; set; }
            public string Email { get; set; }
        }
        public class Order
        {
            public int Id { get; set; }
            public DateTime Date { get; set; }
            public DateTime ShippedDate { get; set; }
            public double Amount { get; set; }
            public Customer Customer { get; set; }
        }

        public static IList<Order> GetOrders()
        {
               if (_orders == null)
                    {
                        var today = DateTime.Now.Date;
                        var customers = GetCustomers();
                        _orders = new List<Order>();
                        for (int i = 0; i < 8; i++)
                        {
                            var shipped = today.AddDays(-Rand.Next(-1, 3000));
                            var order = new Order
                            {
                                Id = i,
                                Date = shipped.AddDays(-Rand.Next(1, 5)),
                                ShippedDate = shipped,
                                Amount = Rand.Next(10000, 500000) / 100,
                                Customer = customers[Rand.Next(0, customers.Count - 1)],
                            };
                            _orders.Add(order);       }
            }
            return _orders;
        }
        public static IList<Customer> GetCustomers()
        {
            if (_customers == null)
                    {
                        var firstNames = new[] { "Aaron", "Paul", "John", "Mark", "Sue", "Tom", "Bill", "Joe", "Tony", "Brad", "Frank", "Chris", "Pat" };
                        var lastNames = new[] { "Smith", "Johnson", "Richards", "Bannon", "Wong", "Peters", "White", "Brown", "Adams", "Jennings" };
                        var cities = GetCities();
                        var states = new[] { "SP", "RS", "RN", "SC", "CS", "RT", "BC" };

                        _customers = new List<Customer>();
                        for (int i = 0; i < 50; i++)
                        {
                            var first = firstNames[Rand.Next(0, firstNames.Length - 1)];
                            var last = lastNames[Rand.Next(0, lastNames.Length - 1)];
                            var customer = new Customer
                            {
                                Id = i,
                                Name = first + " " + last,
                                Address = Rand.Next(100, 10000) + " " + lastNames[Rand.Next(0, lastNames.Length - 1)] + " St.",
                                City = cities[Rand.Next(0, cities.Count - 1)],
                                State = states[Rand.Next(0, states.Length - 1)],
                                Email = first + "." + last + "@gmail.com",
                                                            };
                            _customers.Add(customer);
                        }               
            }
            return _customers;
        }
        public static IList<string> GetCities()
        {
          {
                if (_cities == null)
                    {
                        _cities = new[] { "York", "Paris", "Rome", "Cairo", "Florence", "Sidney", "Hamburg", "Vancouver" };
                    }
                }      
            return _cities;
        }    }
}

Step 2: Add a MultiRow Control

To add a MultiRow control to the application, follow these steps:

Add a new Controller

1. In the Solution Explorer, right click the folder Controllers.
2. From the context menu, select Add | Controller. The Add Scaffold dialog appears.
3. In the Add Scaffold dialog, follow these steps:
   1. Select the Empty MVC Controller template.
   2. Set name of the controller (for example: MultiRowController).
   3. Click Add.
      
4. Include the MVC references as shown below.

   C#	Copy Code
   using MultiRow.Models; using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc;

   
   
5. Replace the method Index() with the following method.
   • C#

   MultiRowController.cs	Copy Code
   public ActionResult Index() { var model = Orders.GetOrders(); return View(model); }

Add a View for the Controller

In the view, we create an instance of MultiRow control and bind it to a data source using .Bind property. The layout definition property helps us to define the column and row layout of the control.

1. From the Solution Explorer, expand the folder Controllers and double click the MultiRowController.
2. Place the cursor inside the method Index().
3. Right click and select Add View. The Add View dialog appears.
4. In the Add View dialog, verify that the View name is Index and View engine is Razor (CSHTML).
5. Click Add to add a view for the controller. Copy the following code and paste it inside Index.cshtml.
   

   Index.cshtml

   Copy Code

   @using MultiRowNetCore.Models @model IEnumerable<Orders.Order> <c1-multi-row id="ovMultiRowCompact" class="multirow"> <c1-items-source source-collection="Model"></c1-items-source> <c1-multi-row-cell-group header="Order" colspan="2"> <c1-multi-row-cell binding="Id" header="ID" width="150" class="id" /> <c1-multi-row-cell binding="Date" header="Ordered" width="150" /> <c1-multi-row-cell binding="Amount" header="Amount" format="c" class="amount" /> <c1-multi-row-cell binding="ShippedDate" header="Shipped" /> </c1-multi-row-cell-group> <c1-multi-row-cell-group header="Customer" colspan="3"> <c1-multi-row-cell binding="Customer.Name" name="CustomerName" header="Cutomer" width="200" /> <c1-multi-row-cell binding="Customer.Email" name="CustomerEmail" header="Customer Email" class="email" colspan="2" /> <c1-multi-row-cell binding="Customer.Address" name="CustomerAddress" header="Address" /> <c1-multi-row-cell binding="Customer.City" name="CustomerCity" header="City"> </c1-multi-row-cell> <c1-multi-row-cell binding="Customer.State" name="CustomerState" header="State" /> </c1-multi-row-cell-group> </c1-multi-row>

Step 3: Build and Run the Project

1. Click Build | Build Solution to build the project.
2. Press F5 to run the project.
   Append the folder name and view name to the generated URL (for example: http://localhost:1234/MultiRow/Index) in the address bar of the browser to see the view.
