<p>How do I expose the <code>ActualWidth</code> property of one of the components of my user control to users?</p>

<p>I have found plenty of examples of how to expose a normal property by creating a new dependency property and binding, but none on how to expose a read-only property like <code>ActualWidth</code>.</p>

```
ActualWidth
```
is a public readonly property (coming from
```
FrameworkElement
```
) and is exposed by default. What is the case that you are trying to achieve?
