Hi Fakhru,

If you want to cancel  the editing of RadtreeViewItem all you have to do is just to handle PreviewEdited event and call  CancelEdit()  as demonstrated in the following sample code:

private void tree_PreviewEdited(object sender, RadTreeViewItemEditedEventArgs e)
        {
            //cancel the edit and return the old value
            if (e.NewText == "123")
            {
                e.Handled = true;
                RadTreeViewItem item = tree.SelectedContainer;
                if (item != null)
                {
                    item.CancelEdit();
                }
            }
....
        }

I hope that this answers your question.
