[Aussie John]

Anyone know if it is possible to page down a portal window? thanks

Not sure what you mean by that. You can always issue a Go to Portal Row[] command. Or perhaps you are looking for something like this:

Thanks Comment.

I wanted the user to be able to quickly scroll through a portal as the arrows tend to be slow.

Your scroll portal file is basically what i am looking for (although i need to try to understand it!!).

Based on your file, what I need to be able to work out is how many rows are being displayed in the portal. Is that possible?

The calculation on which the relationship is based needs to know the number of rows in the portal. In versions before 9, you would just hardcode this into the calc (the demo uses a global field gGroupSize instead). In version 9, where a portal can be stretched to fit window size, this can be more problematic.

I didnt know it could be stretched. Is that a preference?

It's part of the auto-resize layout objects feature.

Some may not be aware that, if you click the portal's scroll bar, you can then use your mouse scroll to quickly move up and down the portal. At least this works in Windows with several types of scroll mice I've used. You can also grab the block within the scroll and drag it downwards quickly. It probably won't replace the functionality you are seeking but I've had it satisfy in some circumstances and it is surprising how some Users don't know this stuff.
