                if (checked) {
                    if ($(this).closest('tr:not(:has(th))').prev().find('th').length == 0) {
                        if ($(this).closest('tr').prev().find($('[id*=checkOrders]'))[0].checked == false) {
                            alert('Please select previous row');
                            return false;
                        }
                    }
                    else {
                        $(this).closest('tr').find('[id*=checkOrders]').attr('checked');
                    }
                }
                else {
                    if ($('[id*=gvOrders] tr:not(:has(th))').length != $(this).closest('tr')[0].rowIndex) {
                        if ($(this).closest('tr').next().find($('[id*=checkOrders]'))[0].checked == true) {
                            alert('Please UnCheck below row');
                            return false;
                        }

                }
            });
        });

</div>

C#

private string constr = ConfigurationManager.ConnectionStrings["ConString"].ToString();
protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        this.GetOrders();
    }
}

private void GetOrders()
{
    using (SqlConnection con = new SqlConnection(constr))
    {
        using (SqlCommand cmd = new SqlCommand("SELECT * FROM Orders ORDER BY [AddCheck] DESC,[purchase_Date] DESC", con))
        {
            DataTable dt = new DataTable();
            using (SqlDataAdapter sda = new SqlDataAdapter(cmd))
            {
                sda.Fill(dt);
                gvOrders.DataSource = dt;
                gvOrders.DataBind();
            }
        }
    }
}
