Grid SmartRendering

Is it possible to limit the number of rows kept in the browser during server side smart rendering?

IE 7 slows down having large number of rows in the browser.

I don’t mind, if the grid asks the server for rows having already visited.

There is no built in settings, but you can call next command at any time

grid._reset_view();

It will clear all already rendered rows and start rendering from the scratch ( loaded data still stored on client side, but just as row data, not as html element )
