How to get the DependencyObject under the mouse cursor

Introduction

With help of VisualTreeHelper and its HitTest() methods, we can easily find the DependencyObject under the mouse cursor.

Use the following code snippet to achieve this.

List<DependencyObject> hitTestList = null;//Raised When Mouse is entered inside Panelprivate void Panel_MouseEnter(object sender, MouseEventArgs e)
    {
        hitTestList = new List<DependencyObject>();       

        Point pt = e.GetPosition(sender as IInputElement);       

        VisualTreeHelper.HitTest(
            sender as Visual, null,
            CollectAllVisuals_Callback,new PointHitTestParameters(pt));       

        hitTestList.Reverse();

        DependencyObject elementToFind = null;foreach (DependencyObject element in hitTestList)
        {if (element.GetType().Name.Equals("ElementToFind"))
            {
                elementToFind = element;// ...// ...}
        }
    }

    HitTestResultBehavior CollectAllVisuals_Callback(HitTestResult result)
    {if (result == null || result.VisualHit == null)return HitTestResultBehavior.Stop;

        hitTestList.Add(result.VisualHit);return HitTestResultBehavior.Continue;
    }
