C# tabpage控件上添加东西

1.继承TABPAGE，并把该添加的控件添加上，然后点击按钮添加继承的那个子控件，

2.往容器里添加控件代码：

Burron

b

=

new

Burron()

b.Location

=

new

Point(10,10)

b.Size

=

new

Size(100,100)

TABPAGE1.Controls.Add(b)

你得指定CheckBox的初始位置,向下面一样

private void button1_Click(object sender, EventArgs e)

{

CheckBox checkBox1 = new CheckBox()

CheckBox checkBox2 = new CheckBox()

CheckBox checkBox3 = new CheckBox()

checkBox1.Text = "AA"

checkBox2.Text = "BB"

checkBox3.Text = "CC"

tabControl1.TabPages[0].Controls.Add(checkBox1)

tabControl1.TabPages[0].Controls.Add(checkBox2)

tabControl1.TabPages[0].Controls.Add(checkBox3)

checkBox1.Location = new Point(50, 20)

checkBox2.Location = new Point(50, 50)

checkBox3.Location = new Point(50, 80)

}

C#重绘TabControl的Tabpage标签，添加图片及关闭按钮

C#重绘TabControl的Tabpage标签，添加图片及关闭按钮就像你介绍到这里了，希望对你有所帮助。
