在C#中如何实现点击左边的treeview的节点，右边显示相应的界面？
在C#中如何实现点击左边的treeview的节点，右边显示相应的界面？
右边的界面应该用什么东西做呢？
很多人说用panel，可是如果节点很多的话，那不是会有很多panel?
我本意是想，每个节点的界面都是单独的winform,然后加载到右边的panel里面，可是运行之后根本不显示加载的窗体啊。
请高手帮忙。。

用父窗口来做。

[解决办法]
不显示，是因为你没有调用窗体的Show方法：
- C# code
private void treeView1_AfterSelect(object sender, TreeViewEventArgs e) { if (e.Node.Name == "节点0") { SettingForm1 stfrm1 = new SettingForm1(); stfrm1.TopLevel = false; stfrm1.FormBorderStyle = FormBorderStyle.None; stfrm1.WindowState = FormWindowState.Maximized; panel1.Controls.Add(stfrm1); stfrm1.Show(); } }
[解决办法]
我做过，就用panel，所有的窗口都在panel中切换
- C# code
Form1 form1 = new Form1form1.TopLevel = false;panel1.Controls.Add(form1);form1.Show();
[解决办法]
跟TreeView放在哪里没有关系的，关键是你不能用splitContainer1.Panel2.Controls.Add(stfrm1);
必须在splitContainer1.Panel2上放一个独立的Panel才行！
splitContainer1.Panel2的类型是：SplitterPanel不是Panel！
[解决办法]
为什么每个界面都要用Form弹出呢，只用一个Form不行吗？
Form的左边是TreeView，右边是Panel，而把每个界面定义一个UserControl，TreeView节点点击之后，动态设置UserControl到Panel不就完了。弹那么多Form用户体验很差的，所有的东西在一个Form当中搞定。
[解决办法]
我的意思是你不要在Panel里面加载form，而是加载一个userControl，将form当中的逻辑移动到userControl当中。将一个form加到一个penel当中，这不符合微软的设计规范。
[解决办法]
用webBrowser.Navigate(url);
url是你treeview被选中节点的属性值
TreeNode tn = this.treeView1.SelectedNode;
string url = "";
if (tn.Tag != null)
{
url = tn.Tag.ToString();
webBrowser1.Navigate(url);
}
Tag存储url

不知道我做的是不是你想要的，比较粗糙，欢迎拍砖。

就是使用UserControl来完成功能。
每一个功能块都是一个UserControl，点击Tree的时候，就可以实例化一个UserControl了。
[解决办法]
从一个Parent的Form当中构造一个孩子Form1，然后Show这个Form1，就会产生线程安全方面的风险，这个Form1上面的某个功能有可能无法使用。如果需求不是很变态，建议一个Form能搞定就使用一个Form，不要在父Form里面创建子Form。并且如果父与子直接有很多的交换，风险就更大了。
