控件的使用问题navBarControl控件,求大神关注

[超级大咸鱼]

不只有人用过navBarControl控件么..
今天试了下 导航能出来就是没内容,navBarControl里我加的treeview，显示不出来,我加其他的控件都显示不出.实在无奈了，求大神关注。
贴出代码：

public void LoadCloMenu()
        {
            if (this.navBarControl1.Groups.Count > 0) this.navBarControl1.Groups.Clear();
            //取出父节点
            DataTable table = Pro_Main_Form.GetFather_Node();
            if (table != null)
            {
                if (table.Rows.Count > 0)
                {
                    //循环添加节点
                    for (int i = 0; i < table.Rows.Count; i++)
                    {
                        NavBarGroupControlContainer groupCon = new NavBarGroupControlContainer();
                        NavBarGroup groupControl = new NavBarGroup();
                        //取出父节点名字
                        groupControl.Caption = table.Rows[i]["MenuCaption"].ToString();
                        //父节点属性
                        groupControl.Tag = table.Rows[i];
                        groupControl.Appearance.Font = new Font("微软雅黑", 12);
                        //根据父节点对应的ID取出子节点
                        DataTable tab = Pro_Main_Form.GetChild_Node(table.Rows[i]["MenuNodeIndex"].ToString());
                        TreeView treeMain = new TreeView();
                        if (tab != null)
                        {
                            if (tab.Rows.Count > 0)
                            {
                                //循环添加子节点
                                for (int j = 0; j < tab.Rows.Count; j++)
                                {
                                    TreeNode ChlidNode = new TreeNode();
                                    ChlidNode.Text = tab.Rows[j]["MenuCaption"].ToString();
                                    ChlidNode.Tag = tab.Rows[j];
                                    treeMain.Nodes.Add(ChlidNode);
                                }
                                //展开所有节点
                                treeMain.ExpandAll();
                                treeMain.Dock = DockStyle.Fill;
                                //添加子节点到控件下
                                groupCon.Controls.Add(treeMain);
                                //设置高度
                                groupCon.Height = ((TreeView)groupCon.Controls[0]).Nodes.Count * 23;
                                //展开所有节点
                                groupControl.Expanded = true;
                                groupControl.ControlContainer = groupCon;
                            }
                        }
                        navBarControl1.Groups.Add(groupControl);
                    }
                }
            }
        }

你的group是不是有个属性，设置是否可以容纳控件啊

我也怀疑是这个问题,我见过其他人加过控件, 所以我试了试, 现在正在找有没有这个属性

...好吧 解决了..
没有直接加父节点的时候把treeview 一起加上去，而是在事件中 加treeview
添加了以下代码：

public void LoadCloMenu()
        {
            if (this.navBarControl1.Groups.Count > 0) this.navBarControl1.Groups.Clear();
            //取出父节点
            DataTable table = Pro_Main_Form.GetFather_Node();
            if (table != null)
            {
                if (table.Rows.Count > 0)
                {
                    //循环添加节点
                    for (int i = 0; i < table.Rows.Count; i++)
                    {
                        NavBarGroup groupControl = new NavBarGroup();
                        //取出父节点名字
                        groupControl.Caption = table.Rows[i]["MenuCaption"].ToString();
                        //父节点属性
                        groupControl.Tag = table.Rows[i];
                        groupControl.Appearance.Font = new Font("微软雅黑", 12);
                        navBarControl1.Groups.Add(groupControl);
                    }
                }
            }
        }
        private void navBarControl1_ActiveGroupChanged(object sender, NavBarGroupEventArgs e)
        {
            NavBarGroupControlContainer groupControl = new NavBarGroupControlContainer();
            NavBarGroup groupControl2 = ((NavBarControl)sender).ActiveGroup;
            DataRow dr = (DataRow)groupControl2.Tag;
            DataTable table = Pro_Main_Form.GetChild_Node(dr["MenuNodeIndex"].ToString());
            if (table != null)
            {
                if (table.Rows.Count > 0)
                {
                    TreeView treeMain = new TreeView();
                    treeMain.Name = "mainMenuTree";
                    treeMain.Font = new System.Drawing.Font("微软雅黑", 10);
                    treeMain.NodeMouseDoubleClick += new TreeNodeMouseClickEventHandler(treeMain_NodeMouseDoubleClick);
                    //循环添加子节点
                    for (int i = 0; i < table.Rows.Count; i++)
                    {
                        TreeNode ChlidNode = new TreeNode();
                        ChlidNode.Text = table.Rows[i]["MenuCaption"].ToString();
                        ChlidNode.Tag = table.Rows[i];
                        treeMain.Nodes.Add(ChlidNode);
                    }
                    treeMain.Dock = DockStyle.Fill;
                    //添加子节点到控件下
                    groupControl.Controls.Add(treeMain);
                    //设置高度
                    groupControl.Height = ((TreeView)groupControl.Controls[0]).Nodes.Count * 23;
                    e.Group.ControlContainer = groupControl;
                    //展开所有节点
                    treeMain.ExpandAll();
                }
            }
        }
