I'm using the following settings:

RecordLoadMode="PreloadRecords"

RecordContainerGenerationMode="PreLoad"

CellContainerGenerationMode="PreLoad"

ScrollingMode="Immediate"

AllowCellVirtualization="False" (in FieldSettings)

On a very dense grid with thousands of rows. When the user scrolls, there is a lag, which seems to indicate the datagrid is still creating the visual tree "on the fly", as opposed to preloading elements. Only once the user has fully scrolled through all data (which is chuggy), does it seem to be caching the visual tree, and subsequent scrolling is smooth as desired.

We would like to ensure that the visual tree is fully loaded at the start, so that scrolling is smooth from the outset. Is this possible?
