New Post: Grouping and virtualization

Hi,

i am looking for a simple example on how to use Grouping in virtualized datagrid in code

i have setup a virtualized datagrid with entity framework and a DataGridVirtualizingCollectionViewSource by handling the QueryItems and the QueryItemCount events, and it work like a charm .


now i want to add groups at runtime by code, but i didn't find any sample .
is the QueryGroups event is what i have to implmement ? , if yes how ?

any help is welcome .

thanks and good day.
