Configuration for DataSourceTransport for update (PUT) against REST API

[Alex]

I am trying to see how to configure the update transport when the remote script is a REST service

Via curl I can perform an update :

curl -X PUT -d "room=1&notes=test test&desc=18 to 25 years" http://myapisite.com/api/room/1

This works fine and updates the remote database.

But I cannot see an example of how to append the parameters via the update transport config; I get this error when attemping to send an edit :

1. Uncaught TypeError: Cannot read property 'data' of undefined kendo.web.min.js:11
   1. ct.extend.setupkendo.web.min.js:11
   2. ct.extend.updatekendo.web.min.js:11
   3. (anonymous function)kendo.web.min.js:11
   4. b.extend.Deferredjquery-1.9.1.js:7541
   5. dt.extend._promisekendo.web.min.js:11
   6. dt.extend._sendkendo.web.min.js:11
   7. dt.extend.synckendo.web.min.js:11
   8. T.extend.saveRowkendo.web.min.js:18
   9. (anonymous function)kendo.web.min.js:18
   10. b.event.dispatchjquery-1.9.1.js:9593
   11. v.handle

I do see when I look @ the grid object while in developer tools that the dataSource data property for the grid is  undefined.   Which makes sense of the error above.  I guess my question is where to define/bind that data property ....

 

grid.options

Object {prefix: "", name: "Grid", columns: Array[4], toolbar: Array[1], autoBind: true…}
