    //else
    //{
    //    sortdir = dir.Substring(0, 3).Trim().ToUpper();
    //}

    string SortExpression = sortfield + " " + (!String.IsNullOrEmpty(dir) ? dir : String.Empty);

I am getting an error saying:

{"Message":"Invalid JSON primitive: DESC.","StackTrace":" at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializePrimitiveObject()\r\n at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth)\r\n at System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize(String input, Int32 depthLimit, JavaScriptSerializer serializer)\r\n at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize(JavaScriptSerializer serializer, String input, Type type, Int32 depthLimit)\r\n at System.Web.Script.Services.RestHandler.GetRawParamsFromGetRequest(HttpContext context, JavaScriptSerializer serializer, WebServiceMethodData methodData)\r\n at System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData, HttpContext context)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.ArgumentException"}

Can anyone help me in this issue?

Sure Here is the JSON store

Ext.ns("FMP");

    FMP.AspNetJsonReader = Ext.extend(Ext.data.JsonReader, {

        read: function(response) {
            // Assuming ASP.NET encoding - Data is stored as 
            var json = response.responseText;
            var o = Ext.decode(json);
            if (!o) {
                throw { message: "AspNetJsonReader.read: Json object not found" };
            }
            if (!o.d) {
                throw { message: "AspNetJsonReader.read: Root element d not found" };
            }
            return this.readRecords(o.d);

        }

    });

    FMP.AspNetJsonStore = Ext.extend(Ext.data.GroupingStore, {
        /**
        * @cfg {Ext.data.DataReader} reader @hide
        */
        constructor: function(config) {
            FMP.AspNetJsonStore.superclass.constructor.call(this, Ext.apply(config, {
                reader: new FMP.AspNetJsonReader(config)
            }));
        }
    });

This is a duplicate question that you already asked. You should have simply re-tagged the original rather than posting a new question with different tags. Now you have people answering the same question in two places (I will not repeat my other answer here).
