Thanks for writing and for your question.
Currently the Pull-to-refresh user experience can be activated only by interacting with DataBoundListBox
, i.e. no API is available for showing the loading animation on top of the list. The point of this feature is to visually guide the user through a pull-to-refresh process which can be started by manipulating the list's contents.
We can consider extending the API to make it possible for the developer to also activate the feature programmatically.
Let me know if you have further questions or need assistance.
