treeviewdocxml is a treeview object, from System.Windows.Forms
        treeViewDocXml.BeginUpdate();
        TreeNode sourceNode = treeViewDocXml.SelectedNode;
        if (sourceNode.Parent == null)
        {
            return;
        }
        if (sourceNode.Index > 0)
        {
            sourceNode.Parent.Nodes.Remove(sourceNode);
            sourceNode.Parent.Nodes.Insert(sourceNode.Index - 1, sourceNode); //HERE CRASH
        }
        treeViewDocXml.EndUpdate();
