I have this event to check/uncheck all child nodes when a node is checked/unchecked. The problem is, that the UltraTree scrolls to the top (The TopNode have not changed).

Or is there a better solution for check/uncheck child nodes when the parent node has changed his checkstate?

        private void ultraTree_AfterCheck(object sender, Infragistics.Win.UltraWinTree.NodeEventArgs e)
        {
            foreach (UltraTreeNode node in e.TreeNode.Nodes)
            {
                node.CheckedState = e.TreeNode.CheckedState;
            }
        }
