tabcontrol动态生成选项卡，并且在选项卡中添加窗体

  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

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 } }
