treeview

I have a treeView with many nodes. I want that some nodes change their image when node collapsed/expanded. How can I do it ?

Unfortunately, TreeNode don't have properties like ExpandNodeImage, CollapseNodeImage \

TreeView can change very often, so nodes can be deleted/added.. i can delete child nodes and so on...

Maybe, there is a class like ExpandAndCollapseNode ?

One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
