How do I update the values of the shape on the property editor

Ok..
i creating a wpf application in which if i dragged shapes to the canvas, they are added to the canvas.


But i have a selectshape button which i am using to select shape after which if i select a particular shape it should display the properties of that shape on the property editor.

this is my code for the xaml...

<Border BorderThickness="2" BorderBrush="LightBlue" Margin="106,41,208,0" Width="390">
          <Canvas Name="canvas1" Background="Transparent" MouseLeftButtonDown="OnMouseLeftButtonDown" MouseMove="OnMouseMove" MouseLeftButtonUp="OnMouseLeftButtonUp" Height="366" Width="386">

          </Canvas>
      </Border>

this the method that addshapes...this works well..

private void AddShape(Point pt1, Point pt2,  string s) 
        {
            path = new Path();
            path.Fill = fillBrush;
            path.Width = canvas1.Width;
            
            path.Height = canvas1.Height;
            path.Stroke = strokeBrush; 
            
            path.StrokeThickness = originalStrokeThickness; 
            if (s == "rectangle") 
            { 
                RectangleGeometry geometry = new RectangleGeometry(); 
                //double width = Math.Abs(pt1.X - pt2.X); 
                //double height = Math.Abs(pt1.Y - pt2.Y); 
                shapename = "Rectangle";
                normalizepoints();
                left = Math.Min(startPoint.X, currentPoint.X); 
                top = Math.Min(startPoint.Y, currentPoint.Y); 
                geometry.Rect = new Rect(left, top, width, height); 
                path.Data = geometry;
                path.Name=shapename;
                savedShape.Add(path);
            }
            else if (s == "ellipse")
            {
                EllipseGeometry geometry = new EllipseGeometry();
                //double width = Math.Abs(pt1.X - pt2.X);
                //double height = Math.Abs(pt1.Y - pt2.Y);
                shapename = "Ellipse";
                normalizepoints();
                 left = Math.Min(startPoint.X, currentPoint.X);
                 top = Math.Min(startPoint.Y, currentPoint.Y);
               
                geometry.Center = new Point(left + width / 2, top + height / 2);
                geometry.RadiusX = width / 2;
                geometry.RadiusY = height / 2;
               
                path.Data = geometry;
                path.Name = shapename;
                savedShape.Add(path);
            }
            else if (s == "hexagon")
            {

                    PathGeometry pg = new PathGeometry(new PathFigure[] { pa });
                    path.Name = shapename;
                    path.Data = pg;
                    savedShape.Add(path);
                
                }
                else
                {
                    PolyLineSegment hexd = new PolyLineSegment(new Point[]

            }
            
            canvas1.Children.Add(path);
            showproperty();
            Canvas.SetTop(path, 0);
            Canvas.SetLeft(path, 0);
            
        }

.



But if i select a shape on the canvas it doesnot update the property editor,,,although i created a propertyclass with properties of width, height, and name..

this is my code for the selection...

if (!canvas1.IsMouseCaptured)
           {
              startPoint = e.GetPosition(canvas1);
           //   selectedPoint = e.GetPosition(canvas1);

               canvas1.CaptureMouse();
               if (rbSelect.IsChecked == true)
               {
                   hitArea = new PointHitTestParameters(startPoint);


                   // Call HitTest method:
                   VisualTreeHelper.HitTest(canvas1, null,
                       new HitTestResultCallback(HitTestCallback),
                       new PointHitTestParameters(startPoint));




               Breakloops:
                   selectedShape = (Path)e.Source;
               foreach (PropertyClass datareal in classdata)
               {

                   foreach (Path path in savedShape)
                   {
                      // MessageBox.Show(path.GeometryTransform.DependencyObjectType.Name);
                       path.StrokeThickness = originalStrokeThickness;
                       if ((path.Name == "Rectangle") && (datareal.Name == "Rectangle"))
                       {
                           var dst = new PropertyClass();
                           dst.Height = datareal.Height;
                           dst.Width = datareal.Width;
                           dst.Name = datareal.Name;
                           xpropertyGrid.DataObject = dst;
                           break;

                       }
                       if ((path.Name == "Ellipse") && (datareal.Name == "Ellipse"))
                       {
                           var dst = new PropertyClass();
                           dst.Height = datareal.Height;
                           dst.Width = datareal.Width;
                           dst.Name = datareal.Name;
                           MessageBox.Show(dst.Name.ToString());
                           xpropertyGrid.DataObject = dst;
                           break;

                       }

                       if ((path.Name == "Hexagon") && (datareal.Name == "Hexagon"))
                       {
                           var dst = new PropertyClass();
                           dst.Height = datareal.Height;
                           dst.Width = datareal.Width;
                           dst.Name = datareal.Name;
                           // MessageBox.Show(dst.Name.ToString());
                           xpropertyGrid.DataObject = dst;
                           break;

                       }

                       // MessageBox.Show(path.Name);

                   }
                   break;
               }

                   selectedShape.StrokeThickness = selectedStrokeThickness;
                   fillBrush = (SolidColorBrush)selectedShape.Fill;
                   e.Handled = true;
                   //pst.Height=






               }

What I have tried:

I have tried using the hittest, but the point is my selectedshape does not tell me what shape i am selecting..

i also collected the shapes to a list, and using a foreach statement to go throught, but all I want is that while looping through, just get me the selected shape so that i can update its properties in the property window
