Hi,
I've a Ajax xombo box (Ajax toolkit 3.5) on my login form when i load the form all goes well the combox is loaded nice..bud when i login to the application i get When i run my website from vs2010 "Object reference not set to a instance" of an object error.
When i remove the control out of the page all goes wel..login goes well..
I've reinstalled the Ajax dll`s removed and reinstalled the references to the dll...I've even delete the temporary web in C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files.
What I'm I missing in this?
