gridview - EXT Grid hangs on reload -
using ext grid display real-time data. grid refreshed once second. scrolling top on every refresh until overrode scrolltotop function.
ext.override(ext.grid.gridview, { scrolltotop: ext.emptyfn });
however, still hangs (prevents scrolling) non-trivial amount of time. how can rid of hang?
obviously grid take some non-trivial amount of time render 400 rows of data. can try reduce rendering workload making grid markup light possible (no fancy renderers etc.), best bet may either wait extjs version 4 (which reputedly offers a huge boost grid performance), or if willing use plugins, have @ ext.ux.livegrid.
