The following example shows how to retrieve the HitTestResult return value from the HitTest method.
' Respond to the left mouse button down event by initiating the hit test. Private Overloads Sub OnMouseLeftButtonDown(ByVal sender As Object, ByVal e As MouseButtonEventArgs) ' Retrieve the coordinate of the mouse position. Dim pt As Point = e.GetPosition(CType(sender, UIElement)) ' Perform the hit test against a given portion of the visual object tree. Dim result As HitTestResult = VisualTreeHelper.HitTest(myCanvas, pt) If result IsNot Nothing Then ' Perform action on hit visual object. End If End Sub
