Need to support Groupping view and Buffered View together Help
since data is very large in my grid ~ 5000 rows grid performance was very slow.
Pagination cannot be implemented as restrictions on pagination in our project.
i used Buffered view it works fine but i need groupingview also but dont know
how to club it together.(live grid not a solution for me now).
please tell me how to combine buffer view and grouping view together.
It is not advisable to display so many records because of browser performance. The main reason being that the rendering overhead of so many rows "hangs" most peoples browsers. It comes down to basic HTML being rendered. That has nothing to do with ExtJS and is a simple browser limitation. I know this doesn't solve your issue.
It looks like you'll need to consolidate the Ext.grid.GroupingView and the Ext.ux.grid.BufferView, but there are so many overlapping methods (eg initTemplates, etc). It looks like a lot of work and I'm really not sure if it's even possible.
