I have seen the syncfusion datagrid demo. In the Data Vitualization Example ,we can use enabldatavirtualization to realize the data virtualization in the sfdatagird. And if I have not impoerted the syncfunsion dlls,then how to realize the data virtualization in original datagird (misscorsoft DataGird)? I get same examples at github,but those are not my desired effect ( like sfdatagrid datavirtualization )
