Diagram and Page "Shape Data" properties are cleared


I am using Aspose.Diagram for .Net v.21.4.0. There is an issue with Document and Page “Shape Data” properties.
I am trying to access it with Page.PageSheet.Props, but a collection is always empty.
Also after just initializing a new Diagram object and saving a document, all of the mentioned properties are cleared.

Best Regards,


Can you please share your sample Diagram file along with sample code snippet? Also, please try using Shape.InheritProps and let us know in case issue still persists.

Hi Asad,

I’ve sent you Visio examples in a private note.
In “Before” example you will be able to see that “Document” and “Page” shapesheets contain “Shape Data” section.
In “After” example there is no such section in “Document” and “Page” shapesheets.
I used a simple code to generate “After” example:
var diagram = new Diagram(filePath);
diagram.Save(filePath, SaveFileFormat.VSDX);

Note: I have an issue with just “Document” and “Page” properties, not Shapes.


Thanks for sharing the sample files.

Hi Philip,

I’ve tested this version and it has just a partial fix :

  1. Document “Shape Data” properties are still cleared
  2. Page “Shape Data” properties are present, but the values are cleared.


Thanks for your feedback. We have re-opened the ticket and will surely look into it according to your feedback. We will let you know once it is completely fixed.


This issue has been fixed in next hotfix 21.7.2.

We could not find this issue. The values of props are present.


Please provide a screenshot of the second issue how values are cleared so that we can further proceed with it.

Hi Asad,

I’ve send you two diagram examples with “Before” and “After” result.
In my application I just used a following code to get values by name:
public static string GetPropertyValueByName(this PropCollection properties, string propertyName)
return properties.Cast().FirstOrDefault(p => p.Name == propertyName)?.Value?.Val;
There was no further edit of values as empty values were returned - except just one property that you will be able to see in “After” diagram.


Alright. We will get back to you soon after analyzing the provided details.


Please use 21.7.2 hotfix in which we have resolved the issue.

Hi Asad,

Thanks for this, but one issue still remains.
“Shape Data” prop value returns an empty value during runtime.
This can be reproduced only when SortIndex of a property has a value:
