Visible records

Is there a way to tell whether a certain record is being displayed in a
grid? I meant not just the recno(grid.recordsource) because it's always
in sight.

Hi Man-wai Chang,

If order is set to 0 and no filter is set (not even DELETED) and the active row
is in the visible part, you could do some calculations with .height, .rowheight,
.headerheight, .activerow, .relativerow and others to find it. But if a filter
is set or an order, then I don't see a reasonable way.
The grid does not disclose such secrets.

If you scrolled vertically with the mouse, the active row can get out of the
visible part of the grid!

I would expect a method to do this... Basically, a way to access each
visible cell's controlsource by actual rows and columns of the grid.

Foxpro 10? :)

On the other hand, why hi-light a row that's out of sight?

I meant from a user perspective, not a programmer.

Maybe it's merely a philosophical question: if a row is out of sight, does it
have a hi-light or not?

take a dynamic-property and let it call a function.
In that function log the Recno() and you have the
visible recnos, as this always is called, if a record
is painted.

But unfortunately there is no event if a reocrd goes
out of sight.

You might zap the recno list, then call grid.refresh()
and get the actively seen records. I didn't try so.

Bye, Olaf.
