I am afraid that we do not have such example. Since there is no getchanges or applychanges methods that come out of the box with the Kendo UI DataSource I would suggest the following:
1. To use the hasChanges method of the Kendo UI DataSource in order to determine whether there is a change in the DataSource.
2. If yes - you can iterate through the data items returned by the data method of the Kendo UI DataSource and check if the dirty field of the data item is true.
3. Each item that has true for dirty field can be pushed in array to contain all modified items.
There is no way to submit the entire grid along with the form since only items for the current page are rendered (therefore hidden inputs will be made only for the current page).
