Hi
Toanpham,From you
query, we understood that you need to clear the checked records of the checkbox
column. clearselection
method is used to deselect the selected rows alone not for checked rows. There
is no separate method to clear the checked records. So we suggest to use the
below workaround solution to clear the checked rows.Refer
to the code below:-

App.Component.ts:-
   
  clearSelectedRows()
  {
         
  (document.getElementsByClassName('e-treeselectall')[0] as HTMLElement
  ).click(); //clear
  the checked rows
      }

Also we would like to know that we don’t have virtualization support for
AutocheckHierarchy feature.Please
get back to us if you need any further assistance.Regards,Farveen
