DotNetNuke function FindControlRecursive -not clear name.

DotNetNuke has function FindControlRecursive. Initially I assumed that it search down hierarchy, but it doesn’t work as I expected.
After reading code it seems that it searched siblings or parens siblings up to the top of hierarchy.
So the name is misleading.


Fortunately  there is a separate function FindControlRecursiveDown, that does what I needed.
