In main window I have mindfusion canvas, so it contains few Nodes(shape) each of this Node properties different to each other,

Ex: I have 4 Rectangles each of these, colors are different.

Main Window




Question 1:

How to redraw(populate) same design on another window once I click button on Main Window

Question 2:

how to populate each of above node's properties in separate section, on second window like following picture

Sorry I unable to mentioned it, Actually I want to clone main window to second window

with all nodes X, Y coordinates and parent diagram canvas all properties (width, height, )

so I tried following

// this is button click on Main window
 

      private void Button_Click(object sender, EventArgs e)
{

var popupDialog = new childWindowPopUp(this);
popupDialog.ShowDialog();
}


// bind diagram to 2nd diagram
// child window code behind file

public partial class childWindowPopUp : Window
{
private readonly MainMindfusionDiragram _mw;
           
public childWindowPopUp()
{
InitializeComponent();

}

public childWindowPopUp(MainMindfusionDiragram mw)
{
InitializeComponent();
_mw = mw;
diagram2.LoadFromString(_mw.diagram1.ToString());
}
}

but this is not bind the digram1 with digram2

getting this error with above

The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters.
