If the ASPxEditBase.EnableClientSideAPI property is set to true, you are allowed to manipulate the editor's list items on the client side by using specific client methods (such as ASPxClientComboBox.AddItem, ASPxClientComboBox.RemoveItem, etc). The EnableSynchronization property controls whether such client item manipulations should be synchronized with the server ASPxAutoCompleteBoxBase.Items collection of the editor.

If ASPxAutoCompleteBoxBase.EnableCallbackMode is set to DefaultBoolean.False, the item synchronization is available; otherwise,
