Hi Bhaweshdeepak,

Thanks for using Syncfusion Products.

Based on your requirement we have created a sample using ASP.NET Web Services and performed the CRUD operation using UrlAdaptor in Grid.

Please refer the sample and code snippet below:
Sample: Sample

public class WebService1 : System.Web.Services.WebService


        static string cons = ConfigurationManager.ConnectionStrings["SQLConnectionString"].ConnectionString;

        static SqlConnection con = new SqlConnection(cons);


        public DataTable Get()     


            SqlCommand getData = new SqlCommand();

            getData.CommandText = "usp_DEV_ChangeLog_Select"; // Stored procedure for retrieve data from suppliers table

            getData.CommandType = CommandType.StoredProcedure;

            getData.Connection = con;

            if (con.State != ConnectionState.Open)


            DataTable sqldata = new DataTable();

            SqlDataAdapter sqladapter = new SqlDataAdapter(getData);

            sqldata.TableName = "Suppliers";


            return sqldata;



In the above code snippet, we have created webservices by using the ASP.NET web service and bound dataSource to Grid, in code behind GetDataSource method.

<ej:Grid ID="Grid" runat="server" AllowPaging="true">

        <DataManager Adaptor="UrlAdaptor" URL="Default.aspx/GetDataSource" UpdateURL="Default.aspx/Update" InsertURL="Default.aspx/Insert" RemoveURL="Default.aspx/Remove" />

           . . . . . . .



        [ScriptMethod(ResponseFormat = ResponseFormat.Json)] // Return the JSON formatted result

        public static object GetDataSource(int skip, int take)


            CRUD_Service.WebService1 service = new CRUD_Service.WebService1();

            var sqldata = service.Get();   // Get data from webservices

            DataResult result = new DataResult();

            List<EditableCustomer> data = (from ord in sqldata.AsEnumerable().Skip(skip).Take(take) // Perform skip take for on demand load paging

                                           select new EditableCustomer


                                               SupplierID = ord.ItemArray[0].ToString(),

                                               CompanyName = ord.ItemArray[1].ToString(),

                                               City = ord.ItemArray[5].ToString(),

                                               PostalCode = ord.ItemArray[7].ToString(),

                                               Country = ord.ItemArray[8].ToString()


            result.result = data;

            result.count = sqldata.Rows.Count;


            return result;


        public class DataResult


            public IEnumerable result { get; set; }

            public int count { get; set; }


By using the following code snippet, we can perform the Add, Edit, Delete actions in Grid. Please refer the below code snippet:


        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]

        public static void Update(EditableCustomer value)


            ExecuteToSQL("usp_DEV_ChangeLog_Update", 0, value, "update"); // perform Update action    



        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]

        public static void Insert(EditableCustomer value)


            ExecuteToSQL("usp_DEV_ChangeLog_InsertUpdate", 0, value, "insert"); // perform add action




        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]

        public static void Remove(int key)


            ExecuteToSQL("usp_DEV_ChangeLog_Delete", key, null, "remove"); // perform delete action


Please refer the documentation for more details using UrlAdaptor:
