Question

I have a ComboBox control. When a particular item is selected, I would like to disable some RadioButton controls.

Is there any particular event that I could use to do that?

Answer 1

You can use SelectionChanged event.

private void comboBox1_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    radioButton1.IsEnabled = comboBox1.SelectedItem == x;

    // or

    radioButton1.IsEnabled = comboBox1.SelectedValue == x;
}
