Is there a way to only load child nodes when the parent node is expanded? The problem that I’m running into is that the “expand” icon doesn’t show up if a node doesn’t have any children. Since I don’t want to load the children until the icon is clicked, I’m left with a bit of a catch 22.
With tree views you usually have to load the children of each displayed node.
So if you only display the root you need to load the roots children too. Once you expand the root you need to load the children of each child if you want the expand stuff for those children.
