Is there a way to determine visible rows in portal?

Or to scroll a specific row into the visible row 1 position?

Here is the issue, I have sets of data in a portal and as the user selects the master record in the above portal, the child portal below scrolls that set into view showing 1st row of that data in first row.

I had the scrolling working by scrolling downward far enough that the first row set of data would appear in first row. But this all broke when the portal auto-sizes for larger screen resolution.

So if I can get an answer to one of the first 2 questions then I should be able to do what is needed.

It's sort of possible, but it would be clumsy at best. You cannot control the scrolling precisely, and if the portal has more rows than the last master has records, there is no way you can shift them up to begin at the first row - see also:

A better way is to put the master record's ID in a global field, and base the relationship to the child on that - so that the portal to child shows ONLY selected master's children.

Yes to the first question...
