Examples

The following code 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 example requires that two RadioButton controls and a ListBox have been instantiated on a form.

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

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

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
