>I dynamically fill a TreeView control at run-time. After loading though, if I click on a Node it opens up a different node or quickly just expands then collapses again. This is only on the first time the node is clicked. After the first click it works totally fine. I have tried using the EnsureVisible method with little success. I don't want anything expanded after the nodes are loaded, but I also don't want the user to have to go through an incorrect expand on the first click. Anyone else ran into this problem?
