Answer 1

该法典将进入用户控制所居住的母窗:

FrameworkElement parent = (FrameworkElement)this.Parent;
        while (true)
        {
            if (parent == null)
                break;
            if (parent is Page)
            {
                //Do your stuff here. MessageBox is for demo only
                MessageBox.Show(((Window)parent).Title);
                break;
            }
            parent = (FrameworkElement)parent.Parent;
        }

为什么你把母窗的所有权与你的控制财产联系起来?
