Selecting Eraser for all InkCanvases opened in tabs

Question

Hello!

 

I'm using below code to load inkCanvases to tabs dynamically in the same tab control 

foreach (var di in DIList)
            {
                var grid = new Grid();
                var inkCanvas = new InkCanvas()
                {
                    Width = grid.Width,
                    HorizontalAlignment = System.Windows.HorizontalAlignment.Left,
                    VerticalAlignment = System.Windows.VerticalAlignment.Top
                };

                SourcePath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"Docs\DI\" + di + ".bmp");
                img = GetBitmap(SourcePath);

                myImageBrush = new ImageBrush(img);

                myCanvas = new Canvas();
                myCanvas.Width = img.Width;
                myCanvas.Height = img.Height;
                myCanvas.Background = myImageBrush;

                inkCanvas.Height = img.Height;
                inkCanvas.Children.Add(myCanvas);
                inkCanvas.DefaultDrawingAttributes.Color = Colors.Red;
                grid.Children.Add(inkCanvas);

                var item = new TabItem();
                item.Header = di;
                item.Content = grid;

                cw.tabCanvas.Items.Add(item);
                // cw.DI.Add(di);
            }

So i want to change the Editing mode InkCanvasEditingMode.EraseByStroke of the Canvases when i click a button. I want it to apply for the all the canvases present. How can i do it.

 

when i do like this inkcanvas1.EditingMode = InkCanvasEditingMode.EraseByStroke it works but i want it to recognize the canvases in present in the tabs and apply erase mode to all. Please help. Much thanks.
