Rendering Grid

I have many rows in a grid (more than load buffering will load by default) and start deleting them for example 3 every time, load buffering will not load the additional rows. If I delete all of them eventually I will have no visible rows but actually there are more. Load buffering seems only to be triggered by the scroll bar. Can we programically load on demand when deleting?

You can  force loading from buffer by next command
