TreeNode[] nodes = this.treeview.Nodes.Find(node.Text, true);
      if (nodes.Length > 0)
      {
        int i = nodes[0].Index;
        if (nodes.Length > 0)
          this.treeview.Nodes.Remove(nodes[0]);
        this.treeview.Nodes.Insert(i, nodes[0]);
      }

i tried this code,

but the node nodes[0] is not inserting into the particular index.

instead it is adding at the last.

but yes i use treeviewsorter.

Any idea how to insert node without using insert

or using insert effectively with treeviewsorter??
