Is it possible to comply all these requirements ?
- the height of the grid shall be fixed whatever the number of records;
- the right space after the last columns shall be never displayed;
- if the number of records is greater than the height of the grid then a vertical scrollbar shall be displayed;
- an horizontal scrollbar shall be never displayed;
- when possible, the height could be adapted in order to not have an "half" displayed record in the bottom of the grid.
- with scroll = true
... and whatever the number of grids on screen OUF !
PS: Oleg has surely the answer ...
