Major Datagrid Issues

[Peter Haworth]

Hi Glen,
Thanks for the suggestions.  In this case, the thumb is firmly anchord at
the bottom of the crollbar, seemingly indictaing that there are no more
rows.

Unfortunatly, references to the dgText have no effect in this environmentt.
 Using the dgNumberOfRecofrds and GetDataOfLine means that I'm taking over
responsibility for the content of the datagrid,  so many of the normal dg
functions and properties have no effect since the dg no longer maintains
it's own internal storage array.

I have found a workaround and that is to call RefreshList right after I've
relaoded the dg with new data.  I hate doing that though because it cause
the whole cycle of calls to GetDataOfLine to happen one more time when
nothing changed.
