I would like to execute an action (i.e. validate the data of a field) when leaving the field as opposed to validating onSave or onDelete. I know I can make custom contexts for validation - I still cannot figure out how to specify what triggers this custom context, but I know it exists.
I looked at http://www.devexpress.com/Support/Center/e/E449.aspx as well, and it is still unclear how I can handle an event that I would get from most common controls such as a "leave" event.
