今天在论坛上看到有人问到，如果在点击TRVEVIEW时动态生成tabcontrol的选项卡，并在选项卡中添加窗体，于是写了一个DEMO,供大家参考

demo下载：http://download.csdn.net/source/2920757

public partial class Form5 : Form
{
public Form5()
{
InitializeComponent();
}

private void Form5_Load(object sender, EventArgs e)
{
TreeNode root = new TreeNode("电话缴费");
root.Name = "root";
treeView1.Nodes.Add(root);

TreeNode tnMobile = new TreeNode("中国移动");
tnMobile.Name = "mobile";
root.Nodes.Add(tnMobile);

TreeNode tnUnion = new TreeNode("中国联通");
tnUnion.Name = "union";
root.Nodes.Add(tnUnion);
root.Expand();

}

private TabPage tbMobile = null;
private TabPage tbUnion = null;
private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{

if (treeView1.SelectedNode.Name=="mobile")
{

if (ErgodicModiForm("tbmobile", tabControl1))
{
tbMobile = new TabPage("中国移动");

tbMobile.Name = "tbmobile";
tabControl1.Controls.Add(tbMobile);

Form6 form = new Form6();
form.TopLevel = false;
form.BackColor = Color.White;
form.Anchor = AnchorStyles.Top | AnchorStyles.Left | AnchorStyles.Right;

form.FormBorderStyle = FormBorderStyle.None;
form.Show();
tbMobile.Controls.Add(form);

}

tabControl1.SelectedTab = tbMobile;
}
else if (treeView1.SelectedNode.Name=="union")
{

if (ErgodicModiForm("tbunion", tabControl1))
{
tbUnion = new TabPage("中国联通");
tbUnion.Name = "tbunion";
tabControl1.Controls.Add(tbUnion);

Form2 form = new Form2();
form.TopLevel = false;
form.BackColor = Color.White;
form.Anchor = AnchorStyles.Top | AnchorStyles.Left | AnchorStyles.Right;

form.FormBorderStyle = FormBorderStyle.None;
form.Show();
tbUnion.Controls.Add(form);

}
tabControl1.SelectedTab = tbUnion;
}
}

/// </summary>
/// <param name="MainTabControlKey">选项卡的键值</param>
/// <param name="objTabControl">要添加到的TabControl对象</param>
/// <returns></returns>
private Boolean ErgodicModiForm(string MainTabControlKey, TabControl objTabControl)
{
//遍历选项卡判断是否存在该子窗体
foreach (Control con in objTabControl.Controls)
{
TabPage tab = (TabPage)con;
if (tab.Name == MainTabControlKey)
{
return false;//存在
}
}
return true;//不存在
}
}
