Hi Morteza,
Thank you for contacting Syncfusion support.
We would like to inform you that you can achieve your requirement of ListView in chat UI by scrolling to the end of the ListViewItems while loading initially. So, rotation of the items are not necessary. We have prepared a sample based on your requirement. Please find the sample from the following link.
Can you please check with the above sample and let us know whether the provided sample meets your requirement.
Regards,
Sangeetha Raju.
