[Solved] 'get_postBackElement().id' is null or not an object

[Amy Liu]

Hello!

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

My project has been

    </SLSCommunicationPortal.Properties.Settings>
  </applicationSettings>
</configuration>

developed and tested in solution works fine.

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 which use IIS7.

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.

Hello Amy,

I reviewed your web config and I can confirm it is proper. Though based on the error message, I believe that this is an issue related with a specific page. Can you elaborate on your scenario a bit more? if applicable, you can share the code of the page for further check.

All the best,
Iana
