Item Loading Modes

The ASPxComboBox control supports a three item loading modes.

  • Default Item Loading Mode - all items are loaded to the client side, so all data operations are performed on the client, without generating a round trip to the server.
  • On-Demand Item Loading - items are loaded from the server on demand, via callbacks.
  • Dynamic List Population - you can manually populate a dropdown list with the required item portions, based on the currently applied filter criteria and the performed list scrolling.

Note that when ASPxComboBox is bound (in whole or in part), bound items are added to the view state. When processing a round-trip to the server, ASPxComboBox takes the items that have already been bound, from the view state.
