Hi Julia,

Thanks for your reply.

I copied all the required ISNet.* DLLs from the Intersoft WebUI 2008 R2 SP2 Installation and placed them in a folder in my project. Then I uninstalled the Intersoft Package so that no reference is taken from GAC for any Intersoft DLL. Then I deleted and added all ISNet references from this foolder to the Web Project again.

And after recompilation and execution, it is the same issue.

I'd like to add that after upgradation to .Net 3.5, I started getting " 'IS_ReleaseType' is undefined" JS error on WebCombo. So issue is not only on WebGrid (Image attached too).

May be this helps you pointing out where could be the issue, that WebUI components in the whole application have become problematic all of a sudden. :(

Thanks again for your effort.

Best Regards,

Veenu Munjal
