How to refresh adapter components

Data adapter components have a setting to say whether to refresh the data and how often. But if I say not to refresh, how do I manually refresh the data?

In components with data variables, I simple can remove the get record collection to stop refresh, and then run a get record collection whenever I want to refresh the data.

Also, the pagination settings say I can request to get the count in the response, but how do I access the response?
