Example

[Visual Basic, C#, C++] The following example evaluates a ListBox selection and the Checked property of a RadioButton. When a specified item is selected from the list box, the PerformClick method of another RadioButton is called. This code assumes that two RadioButton controls and a ListBox have been instantiated on a form.

[Visual Basic] 
Private Sub ClickMyRadioButton()
    ' If Item1 is selected and radioButton2 
    ' is checked, click radioButton1.
    If (listBox1.Text = "Item1") And radioButton2.Checked Then
        radioButton1.PerformClick()
    End If
End Sub


[C#] 
private void ClickMyRadioButton()
{
   // If Item1 is selected and radioButton2 
   // is checked, click radioButton1.
   if (listBox1.Text == "Item1" && radioButton2.Checked)
   {
      radioButton1.PerformClick();
   }
}


[C++] 
private:
void ClickMyRadioButton() {
   // If Item1 is selected and radioButton2 
   // is checked, click radioButton1.
   if (listBox1->Text->Equals("Item1") && radioButton2->Checked)
   {
      radioButton1->PerformClick();
   }
}
