e.handled的用法

        void gl_MouseLeftButtonDownCompleted(object sender, GraphicMouseButtonEventArgs e)
        {
            Graphic clickedGraphic = e.Graphic;
            if (clickedGraphic != null)
            {
                DZInfoWindow.Anchor = clickedGraphic.Geometry.Extent.GetCenter();
                DZInfoWindow.IsOpen = true;
                //Since a ContentTemplate is defined, Content will define the DataContext for the ContentTemplate
                DZInfoWindow.Content = clickedGraphic.Attributes;
                myMap.PanTo(clickedGraphic.Geometry);
            }
            e.Handled = true;
            return;
        }


        private void myMap_MouseClick(object sender, Map.MouseEventArgs e)
        {
            DZInfoWindow.IsOpen = false;
            
        }
