Reorder Aspose.Diagram pages

Hi team,

I am using Aspose.Diagram for Python via .Net with a temporary license. aspose-diagram-python==26.1
I am reading a vsdx file which has multiple pages. There is a particular page which I need to move towards end of the document. I tried updating the page.id to diagram.pages.count+1 but the page still shows up at the front instead of back.
Kindly advise

You’re trying to move a specific page to the end of a VSDX file, and changing the Page.Id alone does not change the page’s position in the document.

Possible way to reorder pages

# diagram is an Aspose.Diagram.Diagram instance
page_to_move = diagram.Pages[page_index]   # zero‑based index of the page you want to move

# Remove it from its current location
diagram.Pages.Remove(page_to_move)

# Append it as the last page (or insert at the desired index)
diagram.Pages.Add(page_to_move)            # adds to the end
# or
# diagram.Pages.Insert(diagram.Pages.Count, page_to_move)

After re‑adding the page, save the diagram:

diagram.Save("output.vsdx", Aspose.Diagram.SaveFileFormat.VSDX)

Why this may work

The visual order of pages in a Visio document is generally determined by the order of objects in the Diagram.Pages collection rather than by the Page.Id value. Removing a page and inserting it at a different index changes its position in that collection, which should be reflected when the file is saved.

If this approach does not give the expected result, please share a minimal code snippet that shows how you load the diagram and identify the page you want to move, so we can look into the behavior with Aspose.Diagram v26.1.

Please try this sample code for python,thanks:

  diagram = Diagram(os.path.join(sourceDir, 1.vsdx))

  temp = diagram.pages[0]|
  diagram.pages.remove(temp)
  diagram.pages.add(temp)
  #Save diagram in the VSDX format|
  diagram.save(os.path.join(outputDir, out.vsdx), SaveFileFormat.VSDX)
