Send data to server using Data Adapter

[DeeCanMember]

Hi all,

I have a CRUD application built using jqxgrid that is functional. I want to modify my code such that I can send a parameter from the aspx page to server using the source object. I tried changing request type to POST, but it does not reach the webmethod in the asmx file. Can you please help me with this ?

Thanks

ASPX code:

           var db = {
                param: "abc"
            };
            var PostObj = { 'db': db };
            var source = {
                datatype: "json",
                datafields: [
                { name: 'JOBID' },
                { name: 'PRIORITY' },
                { name: 'LOT' },
                { name: 'PART' },
                ],
                type: 'POST',
                url: 'Service.asmx/GetLH',,
                data: JSON.stringify(PostObj),
                
                updaterow: function (rowid, rowdata){} ,
                deleterow: function (rowid, commit) {}
                }
               var dataAdapter = new $.jqx.dataAdapter(source, {
                contentType: 'application/json; charset=utf-8',
                loadError: function (xhr, status, error) {
                    alert(error);
                },
                downloadComplete: function (data) {
                    var returnData = {};
                    returnData.records = data.d;
                    return returnData;
                }
            });

The code behind in Webservice :

        [WebMethod]
        [ScriptMethod(UseHttpGet = false, ResponseFormat = ResponseFormat.Json)]
        public object GetLH(DieBlock db)
        {
            string part = db.param;
            OracleConnection myOracleConn = OpenDB();
            DataTableReader myDBReader;
            string json;
            myDBReader = ReadLHDB(myOracleConn);
            using (myDBReader)
            {
                json = this.ReadToJsonLH(myDBReader);
            }
            return new JavaScriptSerializer().DeserializeObject(json);
        }
