How to insert,updat and delete data for WCF RIA JSON endpoint

[Ricky]

    Do you have the sample file to demo how to insert, update and delete data for WCF RIA JSON endpoint ?

[Alexander Valchev]

Hello Ricky,

The only available example which shows KendoUI DataSource integration with WCF service could be downloaded from here.

Generally speaking, the DataSource works with Json, Jsonp and XML data. If you are able to send and receive data in one of the aforementioned formats you should be able to perform CRUD operations with Kendo Grid.
In case you need to convert the request parameters to a format suitable for the remote service, you may use the parameterMap function.

In addition, I believe that you may find the following blog post useful:

Hi,Alexander
               Sorry, I didn't make my question clearly, I just used Silverlight WCF RIA webservice, and I also know how to make the JSON end point.
For the Grid page, sort and filter I know how to do.

               But my question is how to make the insert, update and delete data through parameterMap?

Hi Ricky,

I am afraid that your question is a bit unclear. If I understood correctly, you are able to read and display the data, however the create, update and delete operations are not working. Could you please specify what exactly is the problem, do you receive any JavaScript errors?

parameterMap function is intended to provide opportunity for the developer to customize the request parameters according to the specification of the service. It is responsibility of the developer to convert the parameters into a format suitable for the remote service.
