Scrolling refresh problem

When I scroll all the rows disappear momentarily then appear again when I stop, is this anything that can be resolved?

You can disable virtual mode:

obj.setVirtualMode(false);

but this only makes sense when you have less than 100-200 rows.

That did it thanks Alex.

I disabled the virtual mode with this:
obj.setVirtualMode(false);

but the grid don't repaint data.

The scroll do nothing!!! it's like don't exists when i'm disabled the Virtual Mode!!!!

the same problem occur when i'm active it, but the grid display the records blank.
