        $.ajax({
            type: 'POST',
            url: 'YourPageNameHere.aspx',
            data: {
                'PostSentByAjax': "true",
                'CurrentColumn': CurrentColumn,
                'recNumSplited': recNumSplited,
                'value': newValue,

            },
            success: function (data) {
                //alert(data);
                if (type == "UpdateUserID") {
                    TBX.setAttribute(defaultValue, newValue);

                    refreshData();

                    window.form1.submit();
                }

                if (type == "delete") {
                    document.getElementById("row_" + rowid).style.display = "none";
                    document.getElementById("totalMins").innerHTML = "<span style='text-decoration:underline;color:#A7C942;cursor:pointer;' onclick='refreshData();'>Refresh Results</span>";
