Question

I was trying to implement drag and drop in treeview .
I generate the root nodes first then if I drag any item over the treeview I want to put it under exact root nodes.
I need something like

private void treeView1_DragOver(object sender, DragEventArgs e)
{
TreeNode tNode = FindNodeAtPoint(e.X, e.Y); 
}

so that from tNode I can find it’s root node and can populate it under that parent node.

can anybody help me out with findNodeAtPoint() functionality.

private TreeNode FindNodeAtPoint(int x, int y)
        {            
            Point p = new Point(x, y);
            p = PointToClient(p);
            ................
            ................
            ................
        }

I think it’s what you need. especially the part of GetNodeAt method.
