Adding those two lines for IIS 7 breaks my site. I have a button that shows an tool tip and if I add those, the pop up error goes away, but when I try to show the tool tip, it gives me this error. If I remove those lines, then the pops up come back, but the site works. Any ideas?

Hello,

Unfortunately the provided errors does not give enough information so we could isolate the root cause of the issue. Therefore I would suggest you to open a regular support ticket and send us runnable version of your ablactation as well as detailed steps for replicating the issue on our end. Thus we will be able to debug the project locally and do our best to provide proper solution.

Regards,

So this page is really complicated and it would take me a long time to get something you could use. However, I can provide you with the code here, and access to my dev site so you can reproduce it. Just go here http://parts.intellicomweb.com/admin/products/product.aspx?id=-163 login with testadmin t3st@dm1n and click the add drawing button towards the bottom. Here is the code running on that page

Hi,

I watched the video and I can see it shows the same error as illustrated in the screenshot from your first post.
To solve it, you need to register the handlers for RadUpload as suggested from my colleague Maria.

If afterwards other errors come up, you need to work on resolving them as well. Reviewing the conversation I can see you where receiving two server-side errors (NullReferenceException: Object reference not set to an instance of an object). You should be able to easily locate and resolve them if you run the page in debug mode, with F5. If you can share the method and specify on which line the error is thrown, we might be able to help you finding a solution.
