Working in visual studio I found a whole set of AF controls seemingly available for use but not in the documentation (AF User Interface Library Reference). These include controls like AFDataGridView, AFToolStrip, and many more seemingly inheriting standard Windows controls.
Should I ignore the ones that are not documented, or conversely should I always use the "AF" version of a control if it exists?
If a control is not documented, it is not intended/designed for reuse by customers, so the best option is to ignore. There are a number of controls that require public exposure because they are either used in multiple OSIsoft applications or because the control itself is used in dialogs that are exposed.
