[dba-VB] VB2005 DatagridView with unbound calculated fields

I'm not sure I understand.  You want the subtotal to appear on the
parent form, not in the parent grid, right?  That should only take
creating a dataset (or reference the datasource of the child grid and
cast it as the appropriate object type) and then doing a compute on it
to sum the value of the column in the child.  You'd raise an event from
the child grid if the value changed and a handler in the parent form
would then recalculate the subtotal.

Hi All
I have a form with a parent and child grids. On the child grid I have 2
unbound calculated fields. And everything works fine. What I need to do
is add a subtotal field for 1 of the calculated fields. And the subtotal
to appear  in a textbox on the form for each parent.
Anyone seen this before? Any sites that may explain how to do it?
