I am new to vaadin-10/12 versions and previously we used vaadin-7/8 versions, Now we planning to upgrade vaadin-12 version of all our applications. But we facing following problems with vaadin 12 version Grid :
I have created application with using vaadin 12 grid and no.of records i added in the grid 100/1000/10000/100000.
1) Basic grid and lazy loading grid without renderers is working perfectly ( which takes very less then 1 sec of all cases like 100/1000/10000/100000 ) , But i have problem with componentrenederer with 100/1000/10000/100000 records:
Three TextBox columns and it takes around 1 second .
Three CheckBox columns and it takes around 1 second.
Three ComoboBox columns and it takes around 2 second.
columns : Three TextBox + Three CheckBox + Three ComoboBox = it takes around 3 second.
Actual my requirement is i want to show more then 10000 records with using componentrenederer with in second.
It is any possibility to show 10000 records with in second?
2) Basic grid (without renderers) problem with selectAll feature:
I added 1000 records and apply selectall it takes 9 secs.
Any problems with same above features ?
Note : Same functionality tested lazy grid and it takes same time and we checked dom elements only visible elements rendered on the browser.
Thanks,
Amar Bogari
