Property Value

true if the check box is checked; otherwise, false.

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();
   }
}
