Hi John,

Thanks for writing and for reporting this issue.

As in the ticket you've submitted regarding another issue in RadDataBoundListBox, I would like to ask you for a sample project reproducing the case which will help us investigate it and fix it. You can use one of both threads to upload a project reproduces both issues.

Thanks for your time.

Regards,
Deyan
