I just hit this bug while working on Windows Terminal. That was not the most pleasant surprise for sure! As a workaround I'm using a ListView
inside my ScrollView
now, which obviously is not a great alternative, but it does work (until this issue is fixed).
Describe the bug
I use the Expander control and encapsulate an itemsRepeater in Content to display a large amount of data (about a few hundred items). When I first expand the Expander control, the content can be displayed correctly, but when I fold it up and expand it again, it becomes a blank space that requires a mouse click or scroll to display. I guess it may be a virtualization issue that caused the rendering to fail. Is there a solution to this problem?
Steps to reproduce the bug
1、Create an Expander Control,And the content contains an ItemsRepeater 2、Fill a large amount datas in this ItemsRepeater 3、Expand the Control -> Collapsed Control -> Expand the Control
Expected behavior
ItemsRepeater can show data correctly
