[flexcoders] PrintDataGrid problem

[Giles Roadnight]

Hi All

I am using a PrintDataGrid to display data on 1 or more pages. I have
headers and footers that are removed on certain pages.

It all works fine except for reports where only 1 page is produced.
Here I get all the data but only the top half of the last row is visible.

I can't see what is making this happen only in this case.

Any ideas?

Thanks Giles.

Code:

<PrintDataGridReport>

<?xml version="1.0" encoding="utf-8"?>
