View Full Version : Grid buffered view and grouping view ?

19 Jul 2010, 12:14 AM
Hi, i begin with the extjs lib and i have a question.
It's possible to use bufferedView for performance problem and it's possible to use groupingView to make a group by in the grid.

Is it possible to have the two possibility working in the same time ?

No, these two extensions can't work together.

You would have to create a single extension that supports both features (which is going to be very hard, because buffered view relies on a fixed row height and grouping view breaks this by inserting groups).

Would using grouping with paging be an option?
Or perhaps the TreeGrid user extension (groups at top level, records at second level)?

Yes and no.
If i use grouping with paging, it's to display 1500 lines in the grid and the performance isn't good.

Thank you for your response.
