Hello Steve,

You are right, "reasonable" limit happens quite before physical limit (actually I never reached any physical limit). :)
I would say that over 1000 node to open may have unacceptable execution time, if you do also something else except just adding a node.

In my case it was from 5 to 10 lines of code to setup the node (like conditionally setup node picture, select right-click menu for each particular type of node, setup node as parent using a dummy node) in addition to just Nodes.Add(...)
The best solution here is to define the treeview structure the way it loads minimum nodes at each level. For MS treeview
I used the technique with setting up the node as parent (adding 1 dummy node into it) then remove dummy and add actual nodes on Expand(). (If you use ctTree TreeView control you can define node as parent without adding nodes to it.)
