private void InitializeTreeViewWithToolTips()
{
    treeViewWithToolTips = new TreeView();
    TreeNode node1 = new TreeNode("Node1");
    node1.ToolTipText = "Help for Node1";
    TreeNode node2 = new TreeNode("Node2");
    node2.ToolTipText = "A Tip for Node2";
    treeViewWithToolTips.Nodes.AddRange(new TreeNode[] { node1, node2 });
    treeViewWithToolTips.ShowNodeToolTips = true;
    this.Controls.Add(treeViewWithToolTips);
