Hi,

i've got exactly the same problem.

it is simalar as explained in http://forums.infragistics.com/forums/p/16036/58390.aspx

Is there allready a solution for it?

Hello Rvdv,

In the link you are pointing the original issue was solved after installing the all .NET service packs. Also I am suggesting you to get the latest service release of NetAdvantage. Which version are you using?
Are you getting this only in a UltraComboEditor? Can you please explain a little more about your scenario and when you got this error?
Thank you.

Sincerely,

Hi Shawn,

Are you able to reproduce the exception in a small sample project and post is here? If so, we could check it out.

I believe I am getting the same error.  It only happens when I'm in the debugger and it happens when I try to Dispose of the UltraComboEditor.  As far as I know, there isn't any threading in my application.

Did you figure anything out?

I am on version 13.1.20131.2079.

Thank you.

Hi All,

I am also not using threading in my Excel Application Level Add-in(at least not intentionally), but I receive the following error message. I am using Visual Studio 2013, update 1, with Infragistics 2013.1. Any help would be greatly appreciated. Cheers.
