# Transposed Grid

## Content



In regular grids, each item is represented by a row with columns that represent the item properties. Whereas, in transposed grids, each item is represented by a column with rows that represent the item properties. TransposedGrid is a FlexGrid extension that supports a grid where the rows and columns are transposed.

MVC allows you to work with the transposed grids by using the [TransposedGrid](/componentone/api/mvc/online-mvc-core/dotnet-api/C1.AspNetCore.Mvc.TransposedGrid/C1.Web.Mvc.TransposedGrid.TransposedGrid-1.html) class. This class allows the grid control to display data using a transposed layout, where columns represent data items and rows represent item properties. In such transposed grids, the column headers appear on the left side of the grid. each item is represented by a column with rows that represent the item properties.

To create an application using a TransposeGrid control for displaying products on the grid columns and their properties on the grid rows, follow these steps:

### Create an MVC Application

Create a new MVC application using the ComponentOne or VisualStudio templates. For more information about creating an MVC application, see [Configuring your MVC Application](/componentone/docs/mvc/online-mvc-core/Configuring-your-MVC-Application) topic.

### Create a Data Source for TransposeGrid

2.  Add a new class to the folder **Models** (for example: `Sale.cs`). See [Adding controls](/componentone/docs/mvc/online-mvc-core/Adding-Controls) to know how to add a new model.
3.  Replace the following code in the new model to define the class that serve as a data source for the TransposeGrid control.
    
    ```csharp
    public class ProductSheet
    {
        public string Name { get; set; }
        public string Image { get; set; }

### Add a TransposeGrid control

Complete the following steps to initialize a TransposeGrid control.

**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.  Complete the following steps in the **Add Scaffold** dialog:
    1.  Select **Empty MVC Controller** template.
    2.  Set name of the controller (for example: `TransposeGridController`).
    3.  Click **Add**.
4.  Include the following MVC references:
    *   using Microsoft.AspNetCore.Mvc;
    *   using MVC\_TransposedGrid.Models;
	> type=note
	> **Note**: Replace **MVC\_TransposeGrid.Models;** with **_\<YourMVCApplicationName>._Models;**<br /> in the references.
5.  Replace the method Index() with the following method.
    
    ```csharp
    public IActionResult Index()
    {
        return View(ProductSheet.GetData());
    }
    ```
    

**Add a View for the controller**:

1.  From the **Solution Explorer**, expand the folder **Controllers** and double click the controller (for example: TransposeGrid`Controller`) to open it.
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**. A view has been added for the controller.
6.  In the Solution Explorer, double click `Index.cshtml` to open it.
7.  Replace the default code of the **Views\\Index.cshtml** file with the one given below to initialize a **TransposeGrid** control.
    
    ```razor
    @model IEnumerable<ProductSheet>
        <script>
            const { url } = require("inspector");
            function loadedRows(grid) {
                let g = grid;
                g.columns.defaultSize = 210;
                setTimeout(function () {
                    g.autoSizeColumn(0, true, 30);
                    g.autoSizeRows();
                    g.rows[0].height = 170;
                });
            }
            function formatItem(panel, r, c, cell) {
                if (panel.cellType == 1) {
                    let binding = panel.rows[r].binding || panel.columns[c].binding;
                    switch (binding) {
                        case 'Image':
                            console.log('<img src="' + cell.textContent + '" draggable="false"/>');
                            cell.innerHTML = '<img src="' + cell.textContent + '" draggable="false"/>';
                            break;
                        case 'Name':
                            cell.innerHTML = '<b>' + cell.innerHTML + '</b>';
                            break;
                        case 'Price':
                            cell.innerHTML = '<span class="price">' + cell.innerHTML + '</span>';
                            break;
                        // rating as stars
                        case 'Rating':
                            let rating = panel.getCellData(r, c, false) * 1,
                                stars = Math.floor(rating),
                                html = new Array(stars + 1).join('&#x2605;');
                            html = '<span class="rating">' + html + '</span>';
                            if (rating > stars) {
                                html += '<span class="star half">&#9734;</span>';
                            }
                            cell.innerHTML = html;
                            break;
                        case 'RAM':
                        case 'ROM':
                            cell.textContent += "GB";
                            break;
                        case 'Battery':
                            cell.textContent += "mAh";
                            break;
