I've walked through the following code in the debugger and it is indeed marking the nodes as expanded=true. However, on the page the nodes do not expand. Does anyone have any suggestions?
private void findAndExpand(RadTreeNode selectedNode)
{
RadTreeNode parentNode = selectedNode.ParentNode;
while (parentNode != null)
{
parentNode.Expanded = true;
parentNode = parentNode.ParentNode;
}
}
