Hi!

DoScroll's speed is dependent on the speed of drawing only one row in grid (top line when scroll up or bottom when scrolld own). So, for grid with k rows displayed, when refreshing speed with all Dynamic* is T, and without is t, then speed of DoScrolls to scroll for centering active row will be T/k * k/2 = T/2, and speed of refreshing without Dynamic* will be t/2. As you see, it is just a half of the speed of complete refresh of the grid, so I think it is worth to clear up Dynamic* properties even for a few DoScrolls.

The professional level of programmer could be determined by level of stupidity of his/her bugs

It is not appropriate to say that question is "foolish". There could be only foolish answers. Everybody passed period of time when knows nothing about something.
