Thank you for posting in the community.
I am attaching a sample which suggest an approach for you requirement. In the DropdownClosing client-side event of the first grid, the selected item values are concatenated in a string (a comma is used as a separator) and the loadItems function is called on the second Dropdown which triggers an AJAX callback.
In the ItemsRequested server-side event of the second grid, the values string passed to loadItems is processed in order to get the list of selected items. Then it is up to you to implement item loading according to your requirements.
Please let me know if this helps.
