We recently upgraded a website solution from Visual Studio 2008 til Visual Studio 2010 and .NET 4.0 run time.
We are using rad controls 2.7.0.

Message: Object doesn't support this property or method
I cannot reproduce the problem on my development environment. But I can reproduce it on my test environment where I'm running an IIS site.
I looked in my bin folder and I found RadComboBox.Net2.dll (version 220.127.116.11).
I'm new to rad controls. Do we need to upgrade the rad controls? Is there a an upgrade guide?
Any help is appreciated.
I found this thread http://www.telerik.com/community/forums/aspnet-ajax/ajax/radajax-broken-in-vs-2010-beta-2-in-master-content-pages.aspx
that has workaround of setting ClientIDMode property of the Page to "AutoID". It worked on my test environments.
1st test environment: Microsoft Windows Server 2003 R2, .NET 4, IIS6
2nd test environment: Microsoft Windows Server 2008 R2, NET 4, IIS 7.5
However it is still not working on our partner test environment: Microsoft Windows Server 2008 Standard, .NET 4, IIS 7.0
It's a puzzle and any help is appreciated.
