Hi
Toanpham,Thanks for contacting syncfusion forum.Query: I would enable autoCheckHierarchy with virtualization but
it's has an errorBased on your
query, we understand you are facing the script error while using the
autoCheckHierarchy with virtualization feature. Before proceeding with this, we would like to let you
know that we don’t have Virtualization support for autoCheckHierarchy feature.
So, it won’t satisfy the autoCheckHierarchy behavior.Kindly get back to us for further assistanceRegards,  Pon
