Datagrid Scrolling

Bob Sneidar via use-livecode
Scrolling the Datagrid on mobile is "terrible" (jerky, pixel by pixel)

I thought this was fixed in Datagrid2?

Maybe that hasn't been released?

There were deeper engine changes to finish the accelerated rendering updates required to fully support DG2. I think that is scheduled for 9.1 now.

Thanks,
Brian

I agree. There has been a very significant deterioration in datagrid
scrolling performance since DG2 and LC9 were introduced. Based on feedback
from user testing we have delayed release of an important iOS app update
because DG scrolling was perceived to be unacceptably slow and visually
jerky. The currently released version of the app uses LC8, DG1 and Monte's
mergDatagridScroller code and it scrolls very smoothly.

DG2 is a wonderful update with many exciting new features. I do hope that
the scrolling performance issue can be addressed soon, so that we can take
advantage of the update.

I'm in a similar bind. Going back to 8 will up unacceptable. So many
problems with Android.
I have to stay with 9.01.RC2...But now i invested time  learing in DG...
so I can't release?

[He pounds his head on the desk.

"Oh Wow is me...after 2 years STILL can't release a decent Android app!"]

I guess I have abandon DG and go for with a manually built,
all-controls-on-the-same-front group,  method.

Unless HQ can give us a head up as to when 9.1 will be released?

I agree, and my clients have confirmed, that scrolling with dg2 is  
jerky compared to dg1. This isn't as noticeable when scrolling at a  
fast rate, but very evident at slower speeds.

As Sannyasin mentioned, I can't go back to LC8 due to lack of iOS12  
compatibility (smooth scrolling is important, but not at the cost of  
the app not even launching).
