Set for the IGrouping nodes

Question

I have a node IGrouping, want to use LINQ to set non-first nodes to be checked.
Don't know what keyword to set the node to be checked.
Thank you

Group.Where(Function(f) f.Index > 0). (Function(f) f.Checked = True)

Answer 1

Try this:

Group.Skip(1).All(Function(n)
                        n.Checked = True
                        Return True
                    End Function)
