Plant a Tree in your Member List!

Thanks for this useful post!

Just wanted to comment here that it seems to me like this doesn't actually create a tree but rather an indented list. The difference here is:

1. If I put this memberlist on a cube view, it is not expandable; all the rows of the list are visible all the time
2. If I use this as the member filter in a member selector button, it shows a flat list even though the indent values are there in the MemberInfos

Looks like getting an expandable tree that also works in a button member filter requires using the .Tree option. Apparently the .Tree member filter only returns the MemberInfo for the top member of the hierarchy with the following properties:

1. DisplayUsingExpandableTree = True
2. SupportsChildren = True

Since it creates the tree only using this one MemberInfo, there doesn't seem to be any way to e.g. filter the descendants in a member rule. This is probably also why things like E#Parent.Tree.Where(...) don't seem to work.

Let me know if I'm mistaken. It would be very useful to be able to filter actual trees that could be used in e.g. member selector buttons.
