1、动态添加选项卡，并加载DataGridVIew，绑定数据

private void MainForm_Load(object sender, EventArgs e)
        {
            int newsId = 0;
            dtType = News_Release.News_BLL.BLL.Cmb_Type(newsId);
            for (int i = 0; i < dtType.Rows.Count; i++)
            {
                TabPage Page = new TabPage();
                Page.Name = dtType.Rows[i]["Classification_ID"].ToString();
                Page.Text = dtType.Rows[i]["Name"].ToString();
                this.tcHomePage.Controls.Add(Page);
                if(i==0)
                {
                    Page.Controls.Add(dataGridView1);
                    this.dataGridView1.Dock = DockStyle.Fill;
                }
            }
            this.dataGridView1.AllowUserToAddRows = false;
            this.dataGridView1.ReadOnly = true;
      this.dataGridView1.DataSource = Login.BLL_Login.MainForm.selectedNews(Convert.ToInt32(dtType.Rows[0]["Classification_ID"].ToString()));
        }

        private void tcHomePage_SelectedIndexChanged(object sender, EventArgs e)
        {
            int newsClassification = Convert.ToInt32(tcHomePage.SelectedTab.Name);
            //string typeName = tcHomePage.SelectedTab.Text;
            tcHomePage.SelectedTab.Controls.Add(dataGridView1);
            this.dataGridView1.Dock = DockStyle.Fill;
            this.dataGridView1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
            this.dataGridView1.AllowUserToAddRows = false;   

            this.dataGridView1.DataSource = Login.BLL_Login.MainForm.selectedNews(newsClassification);
        }

2、新建一个WinForm程序，拖一个TabControl（在tabPages属性里面将默认的两个TabPage删除）和三个Button（增加、删除、修改） 

1. public partial class Form1 : Form  
2.     {  
3.         private int index = 0;  
4.         public Form1()  
5.         {  
6.             InitializeComponent();  
7.         }  
8.   
9.         private void Form1_Load(object sender, EventArgs e)  
10.         {  
11.             //this.tabControl1.SelectedIndex = 1;  
12.         }  
13.   
14.         private void btnAdd_Click(object sender, EventArgs e)  
15.         {  
16.             TabPage Page = new TabPage();  
17.             Page.Name = "Page" + index.ToString();  
18.             Page.Text = "tabPage" + index.ToString();  
19.             Page.TabIndex = index;  
20.             this.tabControl1.Controls.Add(Page);  
21.  
22.             #region 三种设置某个选项卡为当前选项卡的方法  
23.             //this.tabControl1.SelectedIndex = index;  
24.             this.tabControl1.SelectedTab = Page;  
25.             //this.tabControl1.SelectTab("Page" + index.ToString());  
26.             #endregion   
27.   
28.             index++;  
29.         }  
30.   
31.         private void btnRemove_Click(object sender, EventArgs e)  
32.         {  
33.             bool first = true;  
34.             if (index > 0)  
35.             {  
36.                 #region 两种删除某个选项卡的方法  
37.                 this.tabControl1.Controls.RemoveAt(this.tabControl1.SelectedIndex);  
38.                 //this.tabControl1.Controls.Remove(this.tabControl1.TabPages[this.tabControl1.TabPages.Count-1]);  
39.                 #endregion   
40.             }  
41.             else  
42.             {  
43.                 return;  
44.             }  
45.  
46.             #region 用于设置删除最后一个TabPage后，将倒数第二个设置为当前选项卡  
47.             if (first)  
48.             {  
49.                 this.tabControl1.SelectedIndex = --index - 1;  
50.                 first = false;  
51.             }  
52.             else  
53.             {  
54.                 this.tabControl1.SelectedIndex = index--;  
55.             }  
56.             #endregion   
57.         }  
58.   
59.         private void btnUpdate_Click(object sender, EventArgs e)  
60.         {  
61.             this.tabControl1.SelectedTab.Text = "xyt";//修改当前选项卡的属性  
62.             //this.tabControl1.SelectedTab.Name = "";  
63.             //this.tabControl1.SelectedTab.Tag = "";  
64.             //this.tabControl1.SelectedTab.Select();  
65.         }  
66.     }
