Hi JL,

You can just pass in the tree as the Component parameter to SetStatusBarText. Control derives from Component, so you can use any Control for this. My guess is that the StatusBar only uses the component to tell when the mouse has moved outside of it, so it knows when to clear the message. So in this case, the text will show up when you move over a node and will change if you move over another node, but it won't disppear until the mouse leaves the tree. 

You could, of course, fix this by blanking it out yourself.

        private void ultraTree1_MouseMove(object sender, MouseEventArgs e)
        {
            UltraTree tree = (UltraTree)sender;
            UltraTreeNode node = tree.GetNodeFromPoint(e.X, e.Y);
            if (node != null)
                this.ultraStatusBar1.SetStatusBarText(tree, node.Text);
            else
                this.ultraStatusBar1.SetStatusBarText(tree, null);
        }
