In the example I am showing data from the following table:

Data from table
Figure 1

The following is the script of my Employee table:

CREATE TABLE [dbo].[Employee](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Name] [varchar](50) NULL,
[Email] [varchar](500) NULL,
[Country] [varchar](50) NULL,
[ProjectID] [int] NULL,
[ManagerName] [varchar](50) NULL,
CONSTRAINT [PK_Employee] PRIMARY KEY CLUSTERED
(
[ID] 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

The following is the data in my Employee table:

I am making a join with the Project table when showing records from this table.

The following is the Project table:

Figure 3

The following is the script of my Project table:

CREATE TABLE [dbo].[Project](
[ProjectID] [int] IDENTITY(1,1) NOT NULL,
[ProjectName] [varchar](50) NULL,
[ProjectLeader] [varchar](50) NULL,
CONSTRAINT [PK_Project] PRIMARY KEY CLUSTERED
(
[ProjectID] 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

The following is the data in my Project table:

The following is the aspx code:

Now my aspx.cs code is:

using System;
using System.Collections.Generic;
using System.Data;
using System.Data.SqlClient;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace Contains_In_jQuery
{
public partial class Default3 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
BindGridWithDummyRow();
}
}
public void BindGridWithDummyRow()
{
DataTable dt = new DataTable();
dt.Columns.Add("ID");
dt.Columns.Add("Name");
dt.Columns.Add("Email");
dt.Columns.Add("Country");
dt.Columns.Add("ProjectID");
dt.Columns.Add("ManagerName");
gvData.DataSource = dt;
gvData.DataBind();
}
[WebMethod]
public static Employee[] BindEmployees()
{
string connectionString = @"Data Source=INDIA\MSSQLServer2k8; Initial Catalog= TestDB; Integrated Security=true;";
DataTable dt = new DataTable();
List<Employee> employeeList = new List<Employee>();
using (SqlConnection con = new SqlConnection(connectionString))
{
using (SqlCommand command = new SqlCommand("select e.ID, e.Name,e.Email,e.Country,ProjectName,e.ManagerName from Employee as e Inner join project as p on e.ProjectID=p.ProjectID ORDER BY e.Name", con))
{
con.Open();
SqlDataAdapter da = new SqlDataAdapter(command);
da.Fill(dt);
foreach (DataRow dtrow in dt.Rows)
{
Employee employee = new Employee();
employee.ID = Convert.ToInt32(dtrow["ID"].ToString());
employee.Name = dtrow["Name"].ToString();
employee.Email = dtrow["Email"].ToString();
employee.Country = dtrow["Country"].ToString();
employee.ProjectID = dtrow["ProjectName"].ToString();
employee.ManagerName = dtrow["ManagerName"].ToString();
employeeList.Add(employee);
}
}
}
return employeeList.ToArray();
}
}
}

Here when showing records I am setting the row background color where the Country value is India:

If you want to set Column background color then use the following changes:

$(document).ready(function() {
$('#gvData').empty();
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "Default3.aspx/BindEmployees",
data: "{}",
dataType: "json",
success: function(result) {
$("#gvData").append("<tr style='background-color:red; color:white; font-weight:bold;'><td style='text-align:left;'>ID</td><td style='text-align:left;'>Name</td><td style='text-align:left;'>Email</td><td style='text-align:left;'>Country</td><td style='text-align:left;'>Project name</td><td style='text-align:left;'>Manager Name</td></tr>");
for (var i = 0; i < result.d.length; i++) {
var Country = result.d[i].Country;
if (Country.indexOf('India') != -1) {
$("#gvData").append("<tr style='background-color:#DC143C; font-family:Verdana; font-size:10pt;color:White;'><td style='text-align:left;'>" + result.d[i].ID + "</td><td style='text-align:left;'>" + result.d[i].Name + "</td><td style='text-align:left;'>" + result.d[i].Email + "</td><td style='text-align:left; background-color:green;'>" + result.d[i].Country + "</td><td style='text-align:left;'>" + result.d[i].ProjectID + "</td><td style='text-align:left;'>" + result.d[i].ManagerName + "</td></tr>");
} else {
$("#gvData").append("<tr style='background-color:skyblue; font-family:Verdana; font-size:10pt ;'><td style='text-align:left;'>" + result.d[i].ID + "</td><td style='text-align:left;'>" + result.d[i].Name + "</td><td style='text-align:left;'>" + result.d[i].Email + "</td><td style='text-align:left;'>" + result.d[i].Country + "</td><td style='text-align:left;'>" + result.d[i].ProjectID + "</td><td style='text-align:left;'>" + result.d[i].ManagerName + "</td></tr>");
}
}
},
error: function(result) {
alert("Error");
}
});
