Selecting Eraser for all InkCanvases opened in tabs

Jan 14 2018 2:23 PM
Hello!
 
I'm using below code to load inkCanvases to tabs dynamically in the same tab control 
  1. foreach (var di in DIList)  
  2.             {  
  3.                 var grid = new Grid();  
  4.                 var inkCanvas = new InkCanvas()  
  5.                 {  
  6.                     Width = grid.Width,  
  7.                     HorizontalAlignment = System.Windows.HorizontalAlignment.Left,  
  8.                     VerticalAlignment = System.Windows.VerticalAlignment.Top  
  9.                 };  
  10.   
  11.                 SourcePath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"Docs\DI\" + di + ".bmp");  
  12.                 img = GetBitmap(SourcePath);  
  13.   
  14.                 myImageBrush = new ImageBrush(img);  
  15.   
  16.                 myCanvas = new Canvas();  
  17.                 myCanvas.Width = img.Width;  
  18.                 myCanvas.Height = img.Height;  
  19.                 myCanvas.Background = myImageBrush;  
  20.   
  21.                 inkCanvas.Height = img.Height;  
  22.                 inkCanvas.Children.Add(myCanvas);  
  23.                 inkCanvas.DefaultDrawingAttributes.Color = Colors.Red;  
  24.                 grid.Children.Add(inkCanvas);  
  25.   
  26.                 var item = new TabItem();  
  27.                 item.Header = di;  
  28.                 item.Content = grid;  
  29.   
  30.                 cw.tabCanvas.Items.Add(item);  
  31.                 // cw.DI.Add(di);  
  32.             }  
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.
