NullReferenceException in ListViewGroupHeader ArrangeOverride

Hello,

 

I receive often a NullReferenceException in ListViewGroupHeader ArrangeOverride method.

The error happens only in UWP.

Unfortunately, I cannot create a project to reproduce the error.

 

Best regards,

Hello Franz,  

This gives the result of the erroneous behavior - the crash, still, it does not give information on how we can reproduce the error. We need to replicate it on our side in order to test/debug and provide proper assistance.

Hi Franz,

We are not aware of such an issue in ListView on UWP, so I will need more information on the concrete scenario in order to test and research it. 

I understand it's difficult to reproduce it in an isolated project, still, would it be possible to send me at least the ListView definition with all the customizations applied? Also, since you mentioned the exception is observed often, are there any specific steps I could try?

Any additional information you can share on the matter, will be of great help.

I look forward to your reply.
