Form1.BackColor = vbRed
radioButton1.BackColor = vbRed
radioButton2.BackColor = vbRed
End If
End Sub
Private Sub radioButton2_Click()
If radioButton2 = True Then
Form1.BackColor = vbBlue
radioButton1.BackColor = vbBlue
radioButton2.BackColor = vbBlue
End If
End Sub

{
if (radioButton1.getChecked() == true)
this.setBackColor(Color.RED);
}
