Cannot Load Saved Diagram sfDiagram

[Muhammad Ahsan saddique]

Hi,

I am trying to load the previously saved sfDiagram data using the serialization example provided in the documentation: https://help.syncfusion.com/wpf/diagram/serialization

But each time it throws the exception System.NullReferenceException as shown below

I am using .Net6.0 with syncfusion.SfDiagram.Wpf library version 27.2.5 along with Syncfusion.Shared.WPF 27.2.5

Hi Muhammad,

 

Reported issue: An Exception occurs while loading the saved diagram file.

 

We tried to reproduce the reported issue using our serialization sample with your mentioned version NuGet package. However, we were not able to reproduce the issue. The saved file loaded without any exception.

 

Could you please share your saved diagram file? This will help us check the issue more accurately and provide you with the right solution.

 

Regards,

Hi Muhammad,

 

Reported issue: An Exception occurs while loading the saved diagram file.

 

We have validated the reported issue using the provided details. Upon review, we noticed that the file is in .txt format, but its content is actually in XML format. To address this, we created an XML file and loaded it using the SfDiagram.Load method. The loading process worked correctly, and we have attached the output for your reference.

 

Based on this, we suspect that the issue may be due to the file being saved with a .txt extension instead of .xml. To assist you further, we have shared both the tested sample file and the converted XML file for your reference.
