I'm currently testing KendoUI in order to adopt it for new developments and I have two big problems with the ajax request. You can download a complete solution from https://github.com/ragare62/AriUserManagement
in order to test this behaviour. If you load AriUMSolution and start AriUMWebApi and AriUMWebHtml (UserGroupGrid.shtml) you'll access to a Kendo grid page and try to create, update or delete registers.
PUT and DELETE http verbs don't work:
When I specify the "type" attribute in "transport.create" to "POST", "transport.update" to "PUT" and "transport.destroy" to "DELETE" the result is always a request with the "OPTIONS" verb. Reading the JQuery documentation about ajax request I realize that "PUT" and "DELETE" could be problematic. Well, I said to myself I'll work only with "POST" so far, and then it came the second problem.
When change "contentType" the request doesn't work:
In my example when you create a new register a "POST" request is issued but webapi can't deserialize the JSON object in the request body. When I debugged that problem with Fiddler I realized that the Content-Type was "Content-Type: application/x-www-form-urlencoded; charset=UTF-8", if I changed "application/x-www-form-urlencoded" to "application/json" with Fiddler everything worked fine. I tried to fix the content type in "transport.create" with the "contentType" attribute to "application/json". But if I did that, the http verb changes from "POST" to "OPTIONS".
I tested these issues with "html" pages instead of "shtml" pages and with different browsers with the same result.
Any help would be appreciate.
Thanks in advance.
