Hi,

How can I go to another page using QuickReport when one field value changes.
eg.

f1     f2     f3
aaa  bbb  ccc
aaa  bbb  ccc
aaa  bbb  ccc
-----------------
When f3 changes(from ccc to ddd),
it's printed in another page.

f1     f2     f3
aaa  bbb  ddd
aaa  bbb  ddd
aaa  bbb  ddd

Hope to be clear

thanks
Paulo

Hi Paulo,

You could use a GroupBand

The components on the QuickReport are as follows:

GroupHeader
DetailBand

The GroupHeader is a TQRGroup

Set the QRGroup1.Expression to Query1.f3

Set QRGroup1.ForceNewPage to True
