Hi Yahya,
Thanks
for sharing the video demonstration. We have checked your video and prepared a
sample with empty data source on initial load and update the date source on
button click. However, we were unable to replicate the
reported issue. We have attached the sample and video demonstration for your
reference, and we request you to share below details, which will
be useful for us to provide you with a better solution.
1.
How have you used the dropdown list to update
the data source?
2.
Modify the attached sample as issue replicable, if possible.
Sample: https://stackblitz.com/edit/react-myhbmp?file=index.js
Video Demonstration: https://www.syncfusion.com/downloads/support/forum/177508/ze/GridLines-1296952427.zip
Note: If you are not
able to modify the attached sample, then we can schedule a call to check
with this issue.
Regards,
Gopinath.
