Item Load Modes

The ASPxComboBox control supports three item load modes.

  • Default Item Load Mode - loads all items to the client side, so all data operations are executed on the client, without generating a round trip to the server.
  • On-Demand Item Load Mode - uses callbacks to load items from the server on demand.
  • Dynamic List Population - manually populate a dropdown list with the required item portions, based on the currently applied filter criteria and the scroll action performed.

Note that in data-bound mode, the control adds items to the view state. During a callback, the ASPxComboBox takes the bound items from the view state.
