copied!<p>You can programatically test the Visiblity and the <code>HitTestVisible</code> property of an element, however beyond this <strong>you can't actually test</strong> if a click event will be forwarded to the element or swallowed by elements on top of it - because blocking or forwarding clicks can happen in event handler methods which you simply can't determine in a generic way.</p> <p>Take the following example:</p> <ul> <li>You want to test if the <code>ParentElement</code> panel is clickable that has a <code>ChildElement</code> on it</li> <li><code>ChildElement</code> has an event handler attached to it that handles the click event, it's visible and its <code>HitTestVisible</code> property is set to true. </li> <li>Based on this you can't yet decide if the event will be forwarded to <code>ParentElement</code>: in the click event handler of <code>ChildElement</code> it can set the event's <code>Handled</code> property to true that would stop the ParentPanel receiving the event or it could leave it at false, making the ParentPanel receive the event.</li> </ul> <p>Thus if there are custom EventHandlers involved, you won't be able to tell for certain whether an element is clickable or not. The most you can do is check the <code>Visiblity</code> and <code>IsHitTestVisible</code> properties on child and parent elements and check where the children / parents are rendered relative to each other using the <a href="http://forums.silverlight.net/forums/p/38825/111580.aspx" rel="nofollow"><code>TransformToVisual</code></a> method.</p>
