Dharmraj Thakur thanks for helping me .

this is my getcountry code

[WebMethod]

public static string GetCountry()

{

List countryList = new List();

string cs = ConfigurationManager.ConnectionStrings["myConnection"].ConnectionString;

using (SqlConnection con = new SqlConnection(cs))

{

con.Open();

SqlCommand cmd = new SqlCommand("select VCOUNTRYCODE,CountryName from visual_countrymaster order by countryName asc", con);

cmd.CommandType = CommandType.Text;

SqlDataReader dr = cmd.ExecuteReader();

while (dr.Read())

{

Country objCountry = new Country();

objCountry.VCOUNTRYCODE = dr["VCOUNTRYCODE"].ToString();

objCountry.CountryName = dr["CountryName"].ToString();

countryList.Add(objCountry);

}

con.Close();

}

JavaScriptSerializer js = new JavaScriptSerializer();

return js.Serialize(countryList);

}

public class Country

{

public string VCOUNTRYCODE { get; set; }

public string CountryName { get; set; }

}

Hi Ashish,

1. Make sure your C# method GetCountry() is static

2. pass array like this...

var postArr = {
   "ddlCountry" : $('#ddlCountry').val(),
"ddlport" : $('#ddlport').val()
};

$.ajax({
   ...
data: JSON.stringify(postArr),
   ...
});

3. If GetCountry() returns json than Make
          contentType: 'application/json'
    If GetCountry() return something else or not fixed then and remove dataType:'json' and change
         contentType: false

4. I suggest you to show us your GetCountry()

Thanks.

You can use like this :
var $FormData = $(this);
            $FormData .submit(function (e) {
                e.preventDefault();

                $.ajax({
                    type: $FormData.attr('method'),
                    url: $FormData.attr('action'),
                    data:  $FormData.serialize(),
                    success: function (msg) {
                        alert("Request Success  !!!");
                    }
                });
            });
Thanks
