Hello!

I downloaded the lastest telerik for asp.net (Evaluation version for developer). and used VS 2010 for my project.

My project developed and tested in solution works fine (my computer use IIS5.1)

But it throw javascript error: 'get_postBackElement().id' is null or not an object Telerik.Web.UI.WebResource.axd when we move to dev server.

What cause the problem? Is there anything which we didn't install on dev server or anything not in config file?

Please help to save my energy.

Thanks in advance.

I think it may be something wrong on the config file which is not suitable to IIS 7.0

Please help me to figure it out. Thanks! I use telerik.web.ui.dll Version:2011.2.712.40
