>You seem to have done a lot with the treeview. Is there any limit on the number of nodes one can load into it? Maybe not a physical limit, but some point where the treeview begins to really bog down in performance? Just wondering.
This is mostly related to the hardware. It is also related to the way we handle the definition of the nodes. You can define them all at startup. You can also define only the headers which will speed up the startup of the form but will slow down the ongoing process.
As for me on a Pentium 200, generated a treeview with 1000 notes takes about 4 seconds. However, I would believe there is a maximum number but I don't have that value.
