Following is the solution I have used in my current project.

public class NodeSorter : IComparer
{
   public int Compare(object x, object y)
   {
      TreeNode tx = x as TreeNode;
      TreeNode ty = y as TreeNode;
      if (tx.Name== null || ty.Name== null)
         return 0;
      return (-1) * string.Compare(tx.Name.ToString(), ty.Name.ToString());
   }
} 

tvListofItems.TreeViewNodeSorter = new NodeSorter();
tvListofItems.Sort();
