สงสัยเกี่ยวกับ RadioButton คือว่าตอนนี้ผมมีตัวRadioอยู่หลายตัวอ่ะ ซึ่งจะติดปัญาหาตอนที่จะเช็คว่าผู้ใช้เลือกตัวไหนอ่ะ

public void AddRadioButtons()
{
  RadioButton rBut1 = new RadioButton();
  rBut1.Location = new Point(50, 50);
 
  rBut1.AutoCheck = true;
  rBut1.Text = "Checked";
  rBut1.Checked = true;
 
  rBut1.CheckedChanged += new EventHandler(rBut_CheckedChanged);
 
  Controls.Add(rBut1);
 
  RadioButton rBut2 = new RadioButton();
  rBut2.Location = new Point(50, 80);
 
  rBut2.AutoCheck = true;
  rBut2.Text = "UnChecked";
  rBut2.Checked = false;
 
  rBut2.CheckedChanged += new EventHandler(rBut_CheckedChanged);
 
  Controls.Add(rBut2);
}
 
private void rBut_CheckedChanged(object sender, System.EventArgs e)
{
  if (sender is RadioButton)
  {
    RadioButton radiobutton = sender as RadioButton;
    if (radiobutton.Checked)
    {
      radiobutton.Text = "Checked";
    }
    else
    {
      radiobutton.Text = "UnChecked";
    }
  }
}

Public Sub AddRadioButtons()
	Dim rBut1 As New RadioButton()
	rBut1.Location = New Point(50, 50)

	rBut1.AutoCheck = True
	rBut1.Text = "Checked"
	rBut1.Checked = True

	rBut1.CheckedChanged += New EventHandler(AddressOf rBut_CheckedChanged)

	Controls.Add(rBut1)

	Dim rBut2 As New RadioButton()
	rBut2.Location = New Point(50, 80)

	rBut2.AutoCheck = True
	rBut2.Text = "UnChecked"
	rBut2.Checked = False

	rBut2.CheckedChanged += New EventHandler(AddressOf rBut_CheckedChanged)

	Controls.Add(rBut2)
End Sub

Private Sub rBut_CheckedChanged(sender As Object, e As System.EventArgs)
	If TypeOf sender Is RadioButton Then
		Dim radiobutton As RadioButton = TryCast(sender, RadioButton)
		If radiobutton.Checked Then
			radiobutton.Text = "Checked"
		Else
			radiobutton.Text = "UnChecked"
		End If
	End If
End Sub
