Hi Hola,

Thank you for contacting Syncfusion support.

Based on the provided video, we have prepared the sample and checked the issue “Performance issue on scrolling in SfDataGrid” and we couldn’t able to replicate the issue in our end. We have also checked the application in Samsung Galaxy Tab A as well in Mi A1 Android 9 Pie with enabled horizontal scrolling then also it is working fine as we expected. Please provide the details about the tested device and configuration, it will help us to provide the solution earlier.

Please refer the following sample,

Sample Link: https://www.syncfusion.com/downloads/support/directtrac/general/ze/SupportAndroid-2058818458

Note: Syncfusion NuGet version 17.1.0.51

Please check the sample and let us know if you still facing the same issue? If not, please modify the sample based on your scenario and revert us with the more details, so that it will be helpful for us to check on it and provide you the solution at the earliest.

Hi paul,

Thanks for the update.

Based on the provided details we have checked the issue “Performance issue on scrolling in SfDataGrid” we could able to replicate the issue in our end with using the Samsung galaxy tab A. We suspect that the performance will be based on the RAM of the device, due to low RAM there will some performance issue in SfDataGrid too. Please let use known whether you're using the ScrollingMode as a line or set the LoadUIView property in your application and please share the exact version of android device and “RAM” details. It will help us to provide the solution earlier.

Regards,

Balasubramani Sundaram.

Hi Paul,

Thank you for your patience

Currently, we are checking the feasibility of improving the scrolling performance in “SfDataGrid” on a lower-end device with lower configure. We suspect that its case due to the memory consuming high when using a large amount of paint object. So, we are currently working on that feasibility of improving our scrolling performance in a lower-end device and we need some time to check the feasibility and will update you the further details on or before September 26th, 2019.

We appreciate your patience until then.

Hello.

Sorry for posting here after a long time, but I'm having the same problem. The scrolling is unsmooth on my Android device. Are there any news on this?
