Hi DigitalMan,

Thanks for your interests in Syncfusion products.

From your updated stack trace i suspect that your trying to host our updown control inside the Docking Manager element. Anyhow we could not able to reproduce your mentioned issue, as a reference we are sending you a simple sample to demonstrate it. Kindly download the sample from the below mentioned location and try reproducing the issue.

Please let us know are we missing anything.

Regards,
Bala.

Hi,

Thanks for the code snippet and bringing this issue to our attention. We are able to reproduce this issue and it has been fixed internally. This fix would be available in our upcoming development build. If you need our custom assembly urgently, please create a separate Direct-Trac incident [https://www.syncfusion.com/Support/DirectTrac/logon.aspx] about this issue with assembly request.

Please let me know if you have any other queries.

Regards,
Prabu
