Preventing a TreeView control  from collapsing other nodes when selecting new node.

I am getting increasingly frustrated by a peculiar (seemingly default) behavior of the TreeView control (Common Controls 6 version).

Say for example I create a tree with 3 nodes at the root level and 3 child nodes for each parent node. I run the project and use the + / - symbols to expand all three parent nodes. As soon as I click on one of the child nodes, the parent nodes of the other child nodes automatically collapse, leaving the minimum number of expanded nodes needed to provide a path to the selected node.

This behavior doesn't seem to exist in any program on the market which uses TreeViews, even Windows Explorer, but I can't for the life of me work out how to prevent it. Surely this must be driving other developers mad, and yet I can find nothing about it anywhere on the web. Please help!

Behaviour definitely occurs under Windows 2000 and XP using Visual Basic 6, Service Pack 5.

i think your treeview controls SingleSel property is set to true. change it to false and check.

Absolutely correct. I can't believe I didn't check what that property actually did - it just seemed so obvious... SingleSel, prevent multiple nodes from being selected at the same time, like the MultipleSelection property of the ListView control. Why they hell did Microsoft call is SingleSel anyway? Thanks a lot mate, you've put 6 months of frustration to sleep in a single sentence. Points well deserved, however easy the answer ended up being!
