I am afraid that the problem is still not fixed. Currently we cannot offer a solution that works well and does not break other parts of the framework logic. The problem comes from the fact that the virtual scroller is not aware of the height of the detail template which is the main obstacle for us to solve the issue.
Please accept my apology for the inconvenience caused.
As a workaround you may try to:
- reset the virtual scroller at detailCollapse / detailExpand events. As an example:
- reset the _rowHeight of the Grid
Please note that there are many cases in which the workaround will not work. Resetting the scroller may force read of the DataSource, which will rebind the grid and collapse the detail row.
