Server-side Sorting & Filtering
Delegates sorting and filtering to a backend via the sortExternal and filterExternal sentinels, loads records a page at a time via the load event, and shows the built-in loading/no-data states via the loading prop (see <DfGrid> props). See Delegating sorting, filtering, and pagination to a server in the Cookbook for the full wiring.
The demo below starts empty. Click Load data to fetch the first page from the server; subsequent pages arrive automatically as you scroll to the bottom. Clear resets to the empty state. Sort and filter changes always restart from page one.
