When you set the Dynamic* properties, the value you set them to should
be a callable, which is then called every time an update() is received. In the
code above, it should simply be:
self.Form.regIdOfGrid.DyanmicDataSource=functionthatreturnsdataset
Note that the parens have been left off; in your code, though, you are
setting the dynamic prop to a dataset, which is not callable, and won't change.

This builds from the complete dataset, so it will include all columns
in that dataset unless you include the optional 'includeFields' parameter,
which should be a list of just the fields in the dataset which you want
displayed in the grid.
I should note that while both approaches will work, the first will be
much, much faster, since it isn't creating the grid each and every time the
form updates.
