treeview

I have a treeview control that functions like a folder browser. Because loading the entire folder structer from disk is taking a lot of time i'm trying to load only one level at a time. So i have a function that adds nodes for all the folders in the current node.

I thought that the best method would be to run it on the BeforeExpand event of the treeview.

UpdateTreeView(TreeView.SelectedNode);

is not working because clicking the + sign to expand is not selecting the node also.

So how to find the node that is expanding.

The dynamic type in C# 4.0 is a welcome addition to the language. 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
