Hello,

Most probably you received this error because the URL is not correct. You should verify that the URL you type in the designer field is the correct one to the service. For example you can open the service in the browser and check the URL in the browser's address bar.  
The URL would be the same as the service name (e.g. EditingWCFService.svc) only in case the service and the page files are in the same folder in the project. If the service is located in a different folder it should also be a part of the URL.
Here are the settings from the online example demonstrating the markup setup in case the service and the page are in the same folder.

<DataSource>
   <WebServiceDataSourceSettings BaseUrl="EditingWcfService.svc/">
         <Select Url="GetCustomers" DataType="JSON" />
     <Update Url="UpdateCustomers" DataType="JSON" />
     <Insert Url="InsertCustomers" DataType="JSON" />
     <Delete Url="DeleteCustomers" DataType="JSON" />
   </WebServiceDataSourceSettings>
</DataSource>

[{"__type":"ServiceCustomer:#","att_typ_code":"HR_APPLI rwrwer","att_typ_id":214,"description":"APPLICATION FOR EMPLOYMENT","secure_flag":"Y","show_in_hierarchy":"N"}]

Please give your advise for this one.
