How do I enable "full" preloading of grid records? I.e. No virtualization.
posted

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?

    Hello Gaurav,

     

    I have been looking into your description and these are the properties needed for turning off the Virtualization. I did test this out and I it seems I am able to reproduce the reported behavior, this is why I am going to contact our development team to double-check if there is anything they can suggest in this matter. I was wondering if you could please give me your test sample so that I am sure we are working on the exact same thing.

     

    Thanks in advance. Looking forward to hearing from you.
