怎么实现winform左边显示treeview，右边显示点击treeview节点点击后的窗体？

Question

各位大哥大姐，请问怎么在c#的winform中实现左边显示treeview，右边显示点击treeview树节点后的显示的新窗体？

Answer 1

// 假定左边panel1，右边panel2
this.panel2.Controls.Clear();
Form4 form4 = new Form4();
form4.TopLevel = false;
this.panel2.Controls.Add(form4);
form4.Show();

Answer 2

private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
        {
            if (e.Node.Name == "")
            {
                Form1 f= new Form1 ();
                f.TopLevel = false;
                f.FormBorderStyle = FormBorderStyle.None;
                f.WindowState = FormWindowState.Maximized;
                panel1.Controls.Add(f);
                f.Show();
            }
        }

我整个form窗体没有用splitContainer控件，IsMdiContainer设置为true，左边的treeview Dock设置为left。我该怎么来实现每个节点点击后在右边显示新的窗体，显示的窗体随节点的不同显示也不同。
小弟是刚刚开始接触winform，还望各位大哥大姐多多指点迷津，谢谢先~~

Answer 4

splitContainer1.panel1.Controls.Add(f);

Answer 5

给你说个简单的，左边是treeview，右面放个tabcontrol,树节点变化，tabcontrol的tabpage变换

Answer 6

楼上的意思是用splitContainer1控件后再添加如下代码吗？
splitContainer1.panel1.Controls.Add(f);小弟新手，还请多多指点下，方便的话可否给出完整代码，谢谢~

Answer 7

Form4 form4 = new Form4();
form4.TopLevel = false;
this.Controls.Add(form4);
form4.Dock = DockStyle.Right;
form4.Show();你的意思是 不用panel？
不用panel的话感觉比较难控制

Answer 8

那如果用panel是不是用splitContainer1是最简单的啊？

Answer 9

我一般用2个panel + 1个Splitter
代码应该都差不多吧

楼上的大哥可否给段完整的代码？
小弟初学winform...
