<div class="markdown level1 remarks"><p>If there is no CheckBox element, this property returns -1. Setting the property to -1 removes the CheckBox element.</p>
<p>Setting this property value greater than the number of children does not throw an exception. In this case, the
maximum valid value (Children.Count) is used instead (e.g. CheckBoxIndex = 1000).</p>
