Hey I did some testing with datagrid that has a lot of data.
If I make a new 2D view and put the datagrid there, the scrolling in datagrid works.
If there is 3D view behind the 2D GUI then the scrolling doesn't work in datagrid.
I tried putting the datagrid into panel, card, popup and straight to the root of 2D Overlay but the scrolling did not work in any of these test cases.
I assume the 3D view captures the scrolling event?
I set the 3D Container visibilty to hidden but that did not change anything.
The scrolling didn't work with list either.
I tested with Vuforia Studio 9.0.3.
This is true. Scroll widgets cant be scrolled on 3d Layout. You can fix this by placing this scroll widget inside Popup widget 🙂
