'Declaration Public Property IsChecked As Nullable(Of Boolean)
public Nullable<bool> IsChecked {get; set;}
When the check editor is checked the IsChecked will return True. When it's unchecked the property will return False. When it's in indeterminate state the property will return null.
IsChecked, Value and Text are all synchronized. When the editor's value is modified, all three properties will reflect the current state of the check editor.
