Datagrid performance on laptop with touchscreen
Dear Apache Flex community,
I am reaching out to inquire about a performance issue I have
encountered with the DataGrid component when running my application on
touchscreen laptops. Specifically, when scrolling the DataGrid (i.e.,
scrolling down to search for a row), the performance is very slow. In
comparison, when running the application on a laptop without a
touchscreen, scrolling is very fast and smooth.
The issue seems to be consistent across different touchscreen laptops,
including the Asus ZenBook Duo 14 (UX482) and older Lenovo Yoga models.
I was wondering if anyone else in the community has encountered similar
performance issues with DataGrid on touchscreen laptops.
Any insights, suggestions, or experiences related to this issue would be
greatly appreciated. Thank you for your time and assistance.
Best regards,
Julien

Unfortunately, this feature is only implemented for the Spark scroller
component used by the Spark Datagrid.
Is it possible for you to switch to the Spark Datagrid ?

Hello Vincent, thank you for your suggestion.
Actually, I'm currently using the mx.controls.DataGrid component in my
application, which doesn't have a maxDragRate property like the Scroller
component.
Best regards,
Julien

Hi,
You can try setting the maxDragRate static property of the Scroller to
its maximum (60 fps)
Scroller.maxDragRate = 60; Vincent.
