TreeGrid HierarchicalData : select folder -> select children

Hi,

I’m using a TreeGrid with AbstractBackEndHierarchicalDataProvider to a have a lazy-loading because when I’ll use my app I’ll have a lot of files so I think this a good idea

I was wondering if when I select an element which a folder (so a node) it’s possible to select automaticlly all it’s children ?
But I think there is problem because normally the appwon’t know the children yet if the node is not expanded, because now when i select a line which represent a folder, only it is selected, and not all of its children, and I’ve not fonud something similar on the forum
