Hi ramco1917,

Check the example.

Database

For this example I have used of Northwind database that you can download using the link given below.

Download Northwind Database

HTML

<asp:DropDownList ID="ddlCountries" runat="server">
    <asp:ListItem Text="Please select"></asp:ListItem>
    <asp:ListItem Text="France"></asp:ListItem>
    <asp:ListItem Text="Germany"></asp:ListItem>
    <asp:ListItem Text="Canada"></asp:ListItem>
</asp:DropDownList>
<hr />
<asp:ListBox ID="lstCustomers" runat="server"></asp:ListBox>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
    $('#ddlCountries').change(function () {
        $.ajax({
            type: "POST",
            url: "Default.aspx/GetCustomers",
            data: '{country:"' + $(this).val() + '"}',
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (r) {
                var lstCustomers = $("[id*=lstCustomers]");
                lstCustomers.empty();
                $.each(r.d, function () {
                    lstCustomers.append($("<option></option>").val(this['Value']).html(this['Text']));
                });
            }
        });
    });
</script>

Namespaces

using System.Data;
using System.Data.SqlClient;
using System.Configuration;
using System.Web.Services;

Code

[WebMethod]
public static List<ListItem> GetCustomers(string country)
{
    List<ListItem> items = new List<ListItem>();
    string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
    using (SqlConnection con = new SqlConnection(constr))
    {
        using (SqlCommand cmd = new SqlCommand("SELECT * FROM Customers WHERE Country = @Country"))
        {
            cmd.CommandType = CommandType.Text;
            cmd.Parameters.AddWithValue("@Country", country);
            cmd.Connection = con;
            con.Open();
            SqlDataReader sdr = cmd.ExecuteReader();
            while (sdr.Read())
            {
                items.Add(new ListItem { Text = sdr["ContactName"].ToString(), Value = sdr["CustomerID"].ToString() });
            }
            con.Close();
        }
    }

    return items;
}
