I've been using telerik grids for a long time now and been facing an issue lately or lack of my knowledge when it comes to grouping by the collection (not a property). Here's my scenario, I'm showing list of employees in the grid, each employee can have multiple roles and I want to group the data by roles and each group will list all the employees under that role.
I am binding my employees collection to a collectionviewsource and adding the groupdescriptions (collection of employee roles) but it ain't showing anything. I wanted to ask if it is possible to group by the collection in such a scenario? Thank you team telerik
