Hi Roman,
Thank you for using Syncfusion Products.
We would like to let you know that when the RefreshView method is called, the entire list of items is rearranged. And if the content size of particular item is changed, then that item and below items which are visible in view gets rearranged. This is the actual behavior of SfListView. Because the extent of SfListView will not layout properly and which leads to some scrolling issue.
Regards,
Dinesh Babu Yadav
