That should happen automatically. The grid raises a RowNumChanged
event that the form should respond to. If not, you can create an
onRowNumChanged method that will handle that event, and call the
form's update() method.

Paul is probably a better source for this info, as he recently added
this feature and I haven't had a chance to play around with it. The
bizobj property is 'VirtualFields', and you can use it to define
mapping of these derived fields and the functions that generate their
values.
You then need to edit the grid to add a column whose DataField is
this virtual field.

You could do this with a little Dabo magic. The datasets themselves
understand SQL, so you could do something like this:
allData = biz.getDataSet()
reschedData = allData.execute("select * from dataset where reschedule
= 1")
...assuming that 'biz' is your main bizobj. You can then call the new
grid's buildFromDataSet(), passing the 'reschedData' dataset.

This is hard to say without knowing more about the app. But keep in
mind that datasets are tuples, so you could get all the rescheduled
records in a dataset by using a query like the one above, or simply:
[rec for rec in biz.getDataSet()
where rec["rescheduled"] == 1]
I hope this give you enough to get started...
