I've given specific height to my grid, i've lots of records
in the grid. Say, my given height to the grid display 5 records at
a time. The problem is the partial of six record has also coming
beneth the grid! Even I use grid.invalidateDisplayList method, it
also coming at the beneath of the grid! and when i'm scrolling the
grid, that last record of the present display list, still making
some very visual disturbment!
