If you need to process the value in a box every time the user changes this value, you need to
set the CommitChanges property of the box to True to enable callbacks
for the box.
If callback is enabled for a box in a container on a page, the user has changed the box value,
and focus is no longer on the box on the page, the container immediately collects all the
modified data and a callback is created to pass the data to the PXDataSource
control of the page (see the diagram below).
The PXDataSource control creates a remote procedure call to the application
server to execute the Update operation with the modified data on the data view that is
specified as the DataMember property for the container. The data view executes
the sequence of events for update of a data record (for details, see Sequence of Events: Update of a Data Record) on the data in the cache object of
the business logic controller. The cache object raises the events that you can handle to process
the modified data.Figure 1. Usage of the CommitChanges property to process a modified data
