Introduction

Angular UI Grid is a data grid for AngularJS without JQuery that can perform with large data, which is part of the Angular UI suite.

Background

Recently I was searching for a data table that have component like sorting, filtering, pagination, inline editor, responsive and other advance facilities. I have tried to integrate & use Jquery datatable(Angular), but the problem arise while I was trying to pass entire row passing while row click/row selected button click.

It fails to pass angular object (only can pass int, string, boolean) while render, this was a big issue to me as I was using angularJS in application frontend.

I decided to change the entire table, I found Angular UI Grid. Let’s Get Into It:

As we know Angular UI Grid is a part of Angular UI, so we have some facilities. We need to download/install package before we are going to use in our application.

To download the package, go to URL: http://ui-grid.info

SQL Database:

CREATE TABLE [dbo].[tblProducts](
	[ProductID] [int] NOT NULL,
	[ProductTitle] [nvarchar](256) NULL,
	[Type] [nvarchar](50) NULL,
	[Price] [numeric](18, 2) NULL,
	[CreatedOn] [datetime] NULL,
 CONSTRAINT [PK_tblProducts] PRIMARY KEY CLUSTERED 
(
	[ProductID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

Demo Data:

INSERT INTO [tblProducts]
SELECT 1,'Ape Lifestyle Cotton Casual T-Shirt - Gray','Clothing',270.00,getdate()
Union All
SELECT 2,'Cotton Casual Short Sleeve Polo - White','Clothing',790.50,getdate()

MVC Application:

Let’s create a new demo application with visual studio 2015. Select MVC and Web API below. Click OK.

Fig: 2

After loading the initial application template, we need to install the script packages. We need to install two package using NuGet Package installer. First we will install AngularJS and after that we need to add Angular-Ui-Grid. In package manager console write Install-Package angularjs. After successfully installation write Install-Package angular-ui-grid.

Fig: 3

Or we can install packages using NuGet package manager

AngularJS

Fig: 4

AngularJS-uigrid

Fig: 5

Our packages are installed, now we need to add a new controller and generate view to the application. In our master layout we need to add reference of script library.

Fig: 6

In the head section add the ui style reference

Fig: 7

AngularJS

Let’s add folder’s to create angular script.

Ui-Grid

In index.cshtml page add ui-grid directive  

Fig: 9

The loader which will show a loading messaging while data is loading from server.

At bottom end, add angular reference to the page

Model: Our Ui is ready Let’s create a new model in our demo application.  

Fig: 12

I have used api controller to get data from server, which will get called while pagination operate. Api-Controller:

[RoutePrefix("api/Product")]
public class ProductController : ApiController
{
private dbUIGrid_Entities _ctx = null;

[HttpGet, ResponseType(typeof(tblProduct)), Route("GetProducts/{pageNumber:int}/{pageSize:int}")]
public IHttpActionResult GetProducts(int pageNumber, int pageSize)
{
    List<tblProduct> productList = null; int recordsTotal = 0;
    try
    {
        using (_ctx = new dbUIGrid_Entities())
        {
            recordsTotal = _ctx.tblProducts.Count();
            productList = _ctx.tblProducts.OrderBy(x => x.ProductID)
                                    .Skip(pageNumber)
                                    .Take(pageSize)
