How to search parents?

I have construction:

Grid a = ((((usercontrol.Parent as DockPanel).Parent as ScrollViewer).Parent as Grid)

Is it possible to find a tree or a parent element?

example: Grid a = GetFirstParent(userc开发者_Python百科ontrol,"Grid") Grid - is Type element

---

    Grid a = userControl.FindParent<Grid>();

    public static T FindParent<T>(this DependencyObject startElement)
        where T : DependencyObject
    {
        DependencyObject parent = GetParentObject(startElement);
        if (parent == null)
            return null;

        T typedParent = parent as T;
        if (typedParent != null)
        {
            return typedParent;
        }

        return FindParent<T>(parent);
    }

Use the VisualTreeHelper class.

It has a method, GetParent, that returns the parent of a control (a DependencyObject really).
