Grouping at 1000 rows

[andll]

Hello

I have large data source(more then 1000 rowns) with listgrid and want to use grouping on it(and yes i understand it can be slow)

How can i disable 'auto turn off grouping' feature?

What do you mean auto turn off? You mean the grouping option in the header menu? You can simply call ListGrid.setCanGroupBy(false)
