Null Reference Exception #47

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago

In DragDrop.cs

static bool HitTestScrollBar(object sender, MouseButtonEventArgs e)
{
HitTestResult hit = VisualTreeHelper.HitTest((Visual)sender, 
e.GetPosition((IInputElement)sender));
            return hit != null && hit.VisualHit.GetVisualAncestor<System.Windows.Controls.Primitives.ScrollBar>() != null;
}

The HitTestResult was null.  I added the 'hit != null &&' to the condition in 
the return value.
