Datagrid Overlays Controls Below

[Bruce LeMond]

When I start the browse of a web form, the datagrid would
overlay the fields and controls below it. The fields and
controls still show up inside the datagrid (It looks like
a double exposure in a photograph.). I checked the list of
properties, but I don't find anything that will allow the
control of vertical scrolling like it does in window forms
(There is no scroll bar.). How could I keep this overlay
from happing?

Thanks in advance for your help.
