Hi,
I use RadGridView with EnableRowVirtualization="True". ItemsSource is VirtualQueryableCollectionView. GridView contains rows with details(RowDetailsVisibilityMode="Visible"). When VerticalScrollBar from GridView scrolled down(dragging the thumb by mouse), the size of the thumb is decreased.
I investigated that ScrollableHeightPropertyKey calculated without adding detail height at first time then ScrollableHeightPropertyKey is increased by details height(from visible area). ScrollableHeightPropertyKey is private property so i can't affect on it.
The ScrollableHeightPropertyKey growing when i dragging the thumb down(details from visible area). When i arrived to the end of the GridView the thumb size stabilized.
I tried to use ScrollMode="Deferred" but the issue is the same.
Xaml:
When i don't use row virtualization the thumb size stay the same.
Or if i use RowDetailsVisibilityMode="VisibleWhenSelected" also the thumb size staying the same.
Is it possible to overcome this situation?
Thanks to all,
Roman Denysenko
