Hello all,

I've got a UltraWinTree with about 3200 nodes in it. I need to hide some nodes if a condition is met. What I do is:

BeginUpdate();

Start recursion;

if (conditionMet){ ultraTreeNode.visible = false; }

End recursion;

EndUpdate();

What I've found is that it takes ~3.2 seconds to peform this operation if the tree is expanded and ~1.6 seconds if the tree is collapsed. The code has been optimized to set modify only the nodes that are necessary; if a node is hidden, I don't check its child nodes.

Am I doing something wrong, or is this performance typical? Thanks.
