Dynamic Smart Rendering - calling the "load URL" before the end of buffer row is reached

Hi,

In dynamic smart rendering mode i am able to load the grid in chunks but the problem is my query is taking long time to execute So user has to wait with blank page once they reach end of the buffered rows . Is there any option in grid to trigger the "load URL" even before the end ? i.e something like if my buffer size is 100, I want to trigger the "load URL" once the user has scrolled past 50th row.

Thanks!

To pre load 50 rows just add following line to the grid initialization:
mygrid.enablePreRendering(50);
