C#中 选项卡（Tabcontrol）动态添加TabPage

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）

public partial class Form1 : Form

{

private int index = 0;

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

//this.tabControl1.SelectedIndex = 1;

}

private void btnAdd_Click(object sender, EventArgs e)

{

TabPage Page = new TabPage();

Page.Name = "Page" + index.ToString();

Page.Text = "tabPage" + index.ToString();

Page.TabIndex = index;

this.tabControl1.Controls.Add(Page);

#region 三种设置某个选项卡为当前选项卡的方法

//this.tabControl1.SelectedIndex = index;

this.tabControl1.SelectedTab = Page;

//this.tabControl1.SelectTab("Page" + index.ToString());

#endregion

index++;

}

private void btnRemove_Click(object sender, EventArgs e)

{

bool first = true;

if (index > 0)

{

#region 两种删除某个选项卡的方法

this.tabControl1.Controls.RemoveAt(this.tabControl1.SelectedIndex);

//this.tabControl1.Controls.Remove(this.tabControl1.TabPages[this.tabControl1.TabPages.Count-1]);

#endregion

}

else

{

return;

}

#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

if (first)

{

this.tabControl1.SelectedIndex = --index - 1;

first = false;

}

else

{

this.tabControl1.SelectedIndex = index--;

}

#endregion

}

private void btnUpdate_Click(object sender, EventArgs e)

{

this.tabControl1.SelectedTab.Text = "xyt";//修改当前选项卡的属性

//this.tabControl1.SelectedTab.Name = "";

//this.tabControl1.SelectedTab.Tag = "";

//this.tabControl1.SelectedTab.Select();

}

}
