I have loaded a PDF successfully in the control. But when I close the application or try to unload the PDF document using "Unload" function, I get this error:

An unhandled exception of type 'System.ArgumentNullException' occurred in Syncfusion.Pdf.Base.dll
Additional information: Der Wert darf nicht NULL sein.

Any idea how to solve that?

Version: 15.1451.0.37

Hi Christoph, 

Thank you for using Syncfusion product. 

We are afraid that we are unable to reproduce “System.ArgumentNullException” thrown while unloading the PDF document from the PDF viewer control in Windows forms platform. We have created a simple sample to reproduce the reported exception and the sample can be downloaded from the following link, 


Can you please modify the above sample or provide us the sample with which the issue could be reproduced. Also provide the following details which will help us to analyze more and assist you better on the issue.
