What I need to do is, increase the colunm sizes to match that of the table column sizes.

If I have a table Test.dbf can I write something similar to this:

if used("Test")
select Test
use
endif
use Test

thisform.datagrid.recordsource="test"

n=test.column.count

for i=1 to n
thisform.datagrid.column1.with=test.column(i).width
endfor
