I'm using the 2008.1 mingw download, hacking the HomeBudget
code, which is a very nice example, thank you very much.

I added a hidden column to add a RichEdit control as the
editor, and a RichTextView as the display, both of which
I'm bringing up in a second window. All of this also
works very well, thank you again.

RichEdit ertv;
RichTextView rtv;

money.AddColumn(NOTES, "Notes").Edit(ertv).Hidden();

(with RichEdit ertv;)

However, I ran into a problem where the accepted row data would not update the sql database if only the hidden control data
is modified. If one of the visible column entries was modified, then the entire row data was saved correctly, including the hidden row data.

I debugged this and found that GridCtrl::IsModifiedRow()
was not returning true. After several hours of trying
to figure a way to get it to recognize that the hidden
data had been modified, I finally just added

void SetModifiedRow() { row_modified++; }
to GridCtrl.h at line 1177, and then called it from a callback.

money.WhenEndEdit = THISBACK(EndEditNotes);

This seems to work now, but I'd like to know if there are
any other accepted ways of dealing with this issue.
Thanks,
Jay Norwood
