Double click the portal while in layout mode to bring up portal setup. You'll find an option towards the bottom where you can choose the number of rows your portal displays.
Go to layout mode, double-click the portal, set the number of rows to 10.
Is that what you mean?
Thank you both for your reply.
It works well in the first portal showing the first 10 records.
Now I need show #11 to # 20 records. What to do?
Set the initial row to 11 for your second portal.
You are so smart, or I am so stupid. :-)
It helps a lot!
Thank you very much!
Have a good weekend!
