Hi Rajiv Jain,
Unfortunately currently the TreeView does not support grouping sorting or filtering out of the box - they need to be implemented on data level.
The next version of the TreeListView will support sorting and maybe filtering and may be a good replacement of the TreeView in this case.
Since we are currently working on the TreeListView it would be great to know how you expect hierarchical grouping to work.
- Do you expect just the root items to be grouped?
- Should the grouping work in each and every item (level) as well - what if the hierarchy is made up of different type of items?
- Roughly, what is the total number of items that you intend to display?
- What is the maximum depth of the hierarchy of the data?
