We have a page that will be passed in a User's Id to it, and it will have one DropDownList reflecting the User's role, while also allowing them to change their role.
We are looking at leveraging the "change" event for a kendoDropDownList. And inside that event, making a $.ajax call.
We know we can work our way to getting this approach to work, but we were wondering if there was a more straight-forward or recommended approach to take.
For example, should or could we define an "update" action inside the dataSource.transport definition for the dropdownlist, that would somehow be triggered?
Another perspective, is that we have lots of Grids that have dataSource.transport.update definitions, and they are processed with a clean controller method that is passed a DataSourceRequest and an instance of a data object that is being updated. Can we do something similar with a DropDownList?

As far as I can understand, in the described scenario there is a DropDownLists on the page, which allows the user to change its role. According to the selected role, the DataSource of the same DropDownList may vary. If this is the case, using the change event of the widget with an AJAX call is a viable approach.
The DropDownList HTML helper, unlike the Grid, does not allow an Update action to be configured for its DataSource.
