还是关于dev的treelist问题。

我记得在哪里看过这样一个例子，
点击一个combo，就弹出一个treelist供用户选择，忘了是哪个例子了。
各位大佬有实现这个功能的，告诉我一下怎么做，
代码越简单越好。

你是指上面这种吗？
如果是上面这种效果，是用PopupContainerControl来作为下拉框的控件，如下绑定树控件到PopupContainerControl

fTreeContainer = new PopupContainerControl();

            this.Properties.PopupControl = fTreeContainer;



            //添加树

            fTree = new TreeList();

            fTreeContainer.Controls.Add(fTree);

            fTree.Dock = DockStyle.Fill;



            //设置树的属性

            TreeHelper.SetTreeListCommonProperty(fTree); //设置树的公共属性

            fTree.OptionsBehavior.Editable = false; //不允许编辑

            fTree.OptionsMenu.EnableColumnMenu = false; //禁用列菜单



            //设置主键列与父列

            fTree.KeyFieldName = fDataField.TreeKeyFieldName;

            fTree.ParentFieldName = fDataField.TreeParentFieldName;

通过QueryPopUp事件给处理树控件的DataSource数据源，
通过树的AfterExpand，MouseMove处理你要做的事情，
可能有些树的属性你要设置，比如



tree.Font = ResourceService.DefaultFont;

            tree.OptionsView.EnableAppearanceEvenRow = true;

            tree.OptionsView.EnableAppearanceOddRow = true;

            tree.OptionsBehavior.UseTabKey = true;



            tree.Appearance.OddRow.BackColor = Color.White;

            tree.Appearance.OddRow.Options.UseBackColor = true;

            tree.Appearance.EvenRow.BackColor = Color.Linen;

            tree.Appearance.EvenRow.Options.UseBackColor = true;



            tree.OptionsView.AutoWidth = false;



            tree.AfterExpand += new NodeEventHandler(tree_AfterExpand);

            tree.CustomDrawNodeCell += new CustomDrawNodeCellEventHandler(TreeList_CustomDrawNodeCell);



            

            tree.CustomDrawColumnHeader += new CustomDrawColumnHeaderEventHandler(tree_CustomDrawColumnHeader);



            TreeListRowNumberHelper.Do(tree);



            //设置控件的字体

            tree.Appearance.Row.Font = MenuToolService.SystemFont;

            tree.Appearance.SelectedRow.Font = MenuToolService.SystemFont;

            tree.Appearance.OddRow.Font = MenuToolService.SystemFont;

            tree.Appearance.FocusedCell.Font = MenuToolService.SystemFont;

            tree.Appearance.FocusedRow.Font = MenuToolService.SystemFont;

            tree.Appearance.GroupButton.Font = MenuToolService.SystemFont;

            tree.Appearance.GroupFooter.Font = MenuToolService.SystemFont;

            tree.Appearance.HeaderPanel.Font = MenuToolService.SystemFont;

            tree.Appearance.Preview.Font = MenuToolService.SystemFont;

            tree.Appearance.TreeLine.Font = MenuToolService.SystemFont;
