[Arnstein]

We are using the SfChart control in out solution and after we implemented dark mode in our app we are facing a crash when changing between dark and light mode. See output:

Greetings from Syncfusion.   

  

We have checked the reported problem with usage of ChartStripLine in android, but it has been worked fine even with page navigation. But we have validated this based on the stack trace, we are in the planning to share possible condition fix on November 10, 2020.  

 

We appreciate your patience until then.

Hi. Thank you for the fast response. I tried the new nuget, but the problem seem to persist. This is what I got after the update

Hi Arnstein, 

 

Thanks for your confirmation.  

 

As we updated earlier, the reported problem is not reproduced at our end. Based on the stack trace updates only we put the possible fix and update to you.  

 

We suspect it may not reflect due to the cache reference from your old packages. So, could you please remove the cache and then use the provided patch again.  

 

To remove the cache in windows: 

   

Delete the Syncfusion packages from C:\Users\Username\.nuget\packages.   

   

In MAC:   

  

•            In Finder, open up your Macintosh HD folder.   

•            Press Command+Shift+Dot to unhide the folder.   

•            Get the. nuget folder from it.  Delete the Syncfusion Packages. 

 

Delete all bin& obj and then install the provided patch. 

 

And to replicate at our end to proceed this further, could you please share the use case to replicate or else share the reproducing sample if possible? 

 

Regards,
Hemalatha M.

Hi again.

After following your steps to clear the nuget cache, I was able to successfully confirm that I no longer get the ObjectDisposedException. Thanks again for the help and fast response.
