MultiRow for ASP.NET MVC supports a transposed view, which is another way to show tabular data and especially useful when there are few data items. The transposed multi-row aspect repeats the records horizontally instead of vertically like in a traditional grid.

The TransposedMultiRow control extends the FlexGrid control to display data using a transposed layout, where columns represent data items and rows represent item properties, similar to the TransposedGrid control. But in contrast to the TransposedGrid control, the TransposedMultiRow control uses multiple columns to represent each data item. This allows you to create form-like interfaces that can display a large number of rows with minimal vertical scrolling.

The TransposedMultiRow control is represented by the TransposedMultiRow class. The TransposedMultiRow class allows you to customize the grid layout using the LayoutDefinition property, just like the MultiRow control. This property specifies the layout of the cells in the grid, just like the MultiRow control but the resulting view looks different because of transposing. It contains an array of cell group objects. Each cell group specifies how many columns the group should span, and the cells that make up each group.

The following example demonstrates the use of a TransposeMultiRow control for displaying data using a transposed layout. This view uses two rows per record and the layout is divided into three groups: order, customer, and shipper.

Create a Data Source for TransposedMultiRow

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 on MultiRow control.

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;
    private static IList<Shipper> _shippers;

    public class Shipper
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Email { get; set; }
        public string Phone { get; set; }
        public bool Express { get; set; }
    }

    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 Zip { get; set; }
        public string Email { get; set; }
        public string Phone { get; set; }
    }

    public class Order
    {
        public int Id { get; set; }
        public DateTime Date { get; set; }
        public DateTime ShippedDate { get; set; }

Add the TransposedMultiRow Control

To add the TransposedMultiRow control to the application, add the following references and follow the steps below:

• C1.Web.Mvc
• C1.Web.Mvc.MultiRow
• C1.Web.Mvc.TransposedMultiRow

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 MVC 5 Controller - Empty template.
   2. Set name of the controller (for example: TransposedMultiRowController).
   3. Click Add.
4. Replace the method Index() with the following method.

   Index.cshtml	コードのコピー
   public ActionResult Index() { var model = Orders.GetOrders(); return View(model); }

1. From the Solution Explorer, expand the folder Controllers and double click the TransposedMultiRowController.
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
